Cuba's New Policy Framework: Opportunities for Growth and Investment

Rodrigo Malmierca, Minister for Foreign Trade and Investment, Cuba
Chair: Dr Christopher Sabatini, Senior Research Fellow for Latin America, Chatham House; Lecturer, Columbia University, School of International and Public Affairs

Since 2010-11, Cuba has engaged in legal and constitutional reform intended to provide a greater role for private enterprise and foreign investment in the country's state-run economy. New rules have been introduced to provide greater scope and guarantees for foreign investment and adjustments have been made to allow private ownership of land – and in a handful of cases 100 per cent share in ownership of investments.

At the same time, Cuba remains subject to US sanctions and an embargo regime that has left foreign investors weary when deciding whether or not to invest in the country. To what extent have these changes provided the security and confidence for foreign investors to seize on Cuba’s efforts to engage internationally around a range of industries including infrastructure, hospitality, hydrocarbons and small and medium enterprise.

Rodrigo Malmierca, Cuba's minister for trade and investment since 2009, will discuss the most recent changes in Cuba, their implications for development and investors and the viability of the official Economic Development Zone situated at Mariel.

The Morass of Central American Migration: Dynamics, Dilemmas and Policy Alternatives

Chair: Amy Pope, Associate Fellow, Chatham House; US Deputy Homeland Security Adviser for the Obama Administration (2015-17)

2019 has seen a record number of people migrating from Central America’s Northern Triangle – an area that covers El Salvador, Guatemala and Honduras. Estimates from June 2019 have placed the number of migrants at nearly double of what they were in 2018 with the increase in numbers stemming from a lack of economic opportunity combined with a rise in crime and insecurity in the region. The impacts of migration can already be felt within the affected states as the exodus has played a significant role in weakening labour markets and contributing to a ‘brain drain’ in the region. It has also played an increasingly active role in the upcoming US presidential election with some calling for more security on the border to curb immigration while others argue that a more effective strategy is needed to address the sources of migration. 

What are the core causes of Central American migration and how have the US, Central American and now also Mexican governments facilitated and deterred migration from the region? Can institutions be strengthened to alleviate the causes of migration? And what possible policy alternatives and solutions are there that could alleviate the pressures individuals and communities feel to migrate?   

Anita Isaacs, professor of Political Science at Haverford College and co-director of the Migration Encounters Project, and Juan Ricard Ortega, principal advisor for Central America at the Inter-American Development Bank, will join us for a discussion on the core drivers of migration within and across Central America.

Attendance at this event is by invitation only.

The UK, US and Mauritius: Decolonization, Security, Chagos and the ICJ

Chair: Dr Leslie Vinjamuri, Director, US and Americas Programme; Dean, Queen Elizabeth II Academy, Chatham House

The Chagos archipelago in the Indian Ocean has garnered media attention recently after the UK failed to abide by a UN deadline to return the islands to Mauritius. The US has landed in the middle of the dispute as a 1965 agreement with the UK has allowed the US to establish a military base on one of the islands, Diego Garcia, which has since become instrumental in US missions in the Asia-Pacific and the Middle East. 

In February 2019, an Advisory Opinion of the International Court of Justice (ICJ) found that the Chagos archipelago was unlawfully dismembered from Mauritius, in violation of the right to self-determination and that the United Kingdom is under an obligation to end its administration of the Chagos archipelago ‘as rapidly as possible’. The UN General Assembly subsequently voted overwhelmingly in favour of the UK leaving the islands by the end of November 2019 and the right of the former residents who were removed by the UK to return. The UK does not accept the ICJ and UN rulings and argues that the islands are needed to protect Britain from security threats while Mauritius has made clear the base can remain.

Professor Philippe Sands QC, professor of law at University College London and lead counsel for Mauritius on the ICJ case on Legal Consequences of the Separation of the Chagos archipelago from Mauritius in 1965, will be joining Ambassador Richard Burt, US chief negotiator in the Strategic Arms Reduction Talks with the former Soviet Union for a discussion on the fate of the archipelago including the future of the military base and the right of return of former residents.

US 2020: America’s National Security Strategy and Middle East Policy

Invitation Only Research Event

10 February 2020 - 10:30am to 11:30am

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

Dr Kori Schake, Resident Scholar and Director of Foreign and Defense Policy Studies, American Enterprise Institute 
Chair: Dr Leslie Vinjamuri, Director, US and Americas Programme

In the run-up to the 2016 US presidential election, then-candidate Donald Trump made a series of campaign promises concerning US foreign policy towards the Middle East. Since assuming office, President Trump has withdrawn the US from the Joint Comprehensive Plan of Action, withdrawn troops from Syria, relocated the US embassy in Israel to Jerusalem and orchestrated the strike against ISIS leader Abu Bakr al-Baghdadi.

Against a backdrop of Trump's inclination towards withdrawing from the region, countries across the Middle East are being rocked by protests, Turkey’s purchase of Russia’s S-400 missile has threatened to undermine cohesion within NATO and the much hoped for ceasefire in Libya between UN-backed government leader, Fayez al-Sarraj, and opposition leader, Khalifa Haftar, failed to materialize.

In light of the upcoming US elections in November 2020, the future of US national security policy promises to be a prominent issue for the next administration. In this vein, the US and Americas Programme at Chatham House plans a yearlong focus on the pivotal US 2020 elections.

At this event, Dr Kori Schake, director of foreign and defense policy studies at the American Enterprise Institute will discuss the future of US foreign policy towards the Middle East. How have domestic and party politics in the US – and the unfolding presidential campaign – shaped recent policy decisions by the Trump administration? Should we expect policy objectives in the Middle East to remain consistent or shift under a second Trump term? And what direction could US foreign policy towards the region take under a Democratic administration?

Attendance at this event is by invitation only.

Trade, Technology and National Security: Will Europe Be Trapped Between the US and China?

Event participants

Sir Simon Fraser, Managing Partner of Flint Global; Deputy Chairman, Chatham House
Chair: Marianne Schneider-Petsinger, Senior Research Fellow, US and the Americas Programme, Chatham House

The US and China have entered into an increasingly confrontational relationship over trade and technology. This may force Europe to make difficult choices between the two economic superpowers – or perform a balancing act. Although the recent US-China phase-1 trade deal has eased the relationship for now, the trade and technology tensions are a structural issue and are likely to persist.

The debate over Huawei’s participation in 5G networks is an example of how the UK and other countries may face competing priorities in economic, security and foreign policy. Can Europe avoid a binary choice between the US and China? Is it possible for the EU to position itself as a third global power in trade, technology and standard-setting? What strategies should Europeans adopt to keep the US and China engaged in the rules-based international order and what does the future hold for trade multilateralism?

Sir Simon Fraser will join us for a discussion on Europe’s future role between the US and China. Sir Simon is Managing Partner of Flint Global and Deputy Chairman of Chatham House. He previously served as Permanent Secretary at the Foreign and Commonwealth Office (FCO) and Head of the UK Diplomatic Service from 2010 to 2015. Prior to that he was Permanent Secretary at the UK Department for Business, Innovation and Skills. He has also served as Director General for Europe in the FCO and Chief of Staff to European Trade Commissioner Peter Mandelson.

Implications of AMLO and Bolsonaro for Mexican and Brazilian Foreign Policy

Chair: Dr Christopher Sabatini, Senior Research Fellow for Latin America, US and the Americas Programme, Chatham House

The end of 2018 was a monumental year for Latin America’s two biggest economies. In December 2018, Andrés Manuel López Obrador (AMLO) was inaugurated as Mexico’s 58th president. The following month saw another political shift further south, as Jair Bolsonaro became Brazil’s 38th president. While sitting on opposite ends of the political spectrum, both AMLO and Bolsonaro were considered to be political outsiders and have upended the status quo through their election to office. 

To what extent does the election of AMLO in Mexico and Bolsonaro in Brazil represent a shift in those countries’ definitions of national interest and foreign policy priorities? How will this affect these states’ policies regarding international commitments and cooperation on issues such as human rights, environment and climate change, migration, and trade? To what extent do possible shifts reflect changing domestic opinions?  Will any changes represent a long-term shift in state priorities and policies past these administrations?

US 2020: Super Tuesday and Implications for the General Election

Chair: Dr Leslie Vinjamuri, Director, US and the Americas Programme, Chatham House

The US 2020 election season enters a potentially decisive next phase with the Super Tuesday primaries on 3 March. With these fifteen, simultaneously-held state elections, the Democrats hope to have greater clarity about their party’s likely nominee for the general race against President Donald Trump in November. Concerns around intraparty divisions in the Democratic party between progressives (represented by Senators Elizabeth Warren and Bernie Sanders) and moderates (represented by former Vice President Joe Biden and former mayor Pete Buttigieg) have surrounded the primary races so far, and are unlikely to dissipate even if one candidate emerges from the field on 3 March.

Against this backdrop, Chatham House brings together a panel of experts to discuss the state of the Democratic primary race, implications for the general election, and the Trump campaign’s priorities ahead of its re-election bid. Will the Democratic party resolve its divisions and unite behind a progressive or moderate in light of the Super Tuesday election results? How is Trump positioned to fair against the Democratic candidates left in the race? Did Former Mayor of New York Michael Bloomberg’s primary gamble to focus on Super Tuesday pay off? And what policy priorities are likely to be pursued under either a Trump 2.0 or a Democratic administration?

The US is eight months out from consequential presidential and congressional elections. Since his election in 2016, US President Donald Trump has presided over economic expansion and record unemployment rates following a 2017 tax overhaul and deregulation policies. Trump’s approval rating is at the highest level of his presidency, while on the Democratic side, the once-wide field is in a process of narrowing as intra-party ideological differences persist.
 
As we look ahead to the presidential elections in November 2020, Dr Lindsay Newman will reflect on Donald Trump’s presidency, the state of the 2020 election and preview the potential directions of travel ahead under a Trump 2.0 or a Democratic administration. How can we understand the health of Trump’s presidency post-impeachment and post-State of the Union address? What will Trump’s likely foreign policy priorities be ahead of his re-election bid including prospects for a US-UK or a US-Europe trade deal? And, across the aisle, how can we understand the Democratic primary so far and how are the Democrats positioned going into the general election?

Exploring the Obstacles and Opportunities for Expanded UK-Latin American Trade and Investment

Invitation Only Research Event

14 January 2020 - 8:30am to 11:00am

Chatham House | 10 St James's Square | London | SW1Y 4LE

Trade and investment between the UK and Latin America is woefully underdeveloped. Latin America’s agricultural powerhouses Brazil and Argentina only accounted for a total of 1.6% of the UK’s agricultural market across eight sectors in 2018, all of those areas in which Argentina and Brazil have substantial comparative advantages. 

Conversely, UK exports to the large Latin American economies remain far below their potential.  To cite a few examples, in 2018 in the electrical equipment sector, the UK only exported $95.7 million of those products to Brazil, making the ninth largest economy in the world only the 42nd export market for those goods from the UK; Mexico only imported $91.4 million of UK-made electrical goods, placing it directly behind Brazil as UK’s market for those goods.

As we look to the future, any improvement to the relationship will depend on two factors: 1) how the UK leaves the EU and 2) whether Latin American agricultural producers can improve their environmental practices and can meet the production standards established by the EU and likely maintained by a potential post-Brexit Britain.

In the first meeting of the working group,  Chatham House convened a range of policymakers, practitioners and academics to explore this topic in depth, identify the key issues driving this trend, and begin to consider how improvements might best be made. Subsequent meetings will focus on specific sectors in commerce and investment.

Immature leadership: Donald Trump and the American presidency

4 March 2020 , Volume 96, Number 2

Daniel W. Drezner

There has been a renaissance in the study of how the backgrounds of individual leaders affect foreign policy outcomes. Donald Trump's presidency highlights the limits of this approach. Trump's psychology is so unique, and so akin to that of a small child, that studying his background alone is insufficient to explain his decision-making. The evidence for this characterization of Trump's leadership comes not from his political opponents, but his allies, staffers and subordinates. Trump's lack of impulse control, short attention span and frequent temper tantrums have all undercut his effectiveness as president as compared to his predecessors. Nonetheless, the 45th president helps to clarify ongoing debates in American politics about the relative strength of the presidency as an institution. In particular, the powers of the presidency have become so enhanced that even comparatively weak and inexperienced leaders can execute dramatic policy shifts. The formal checks on presidential power, from the legislative, judicial and executive branches have all eroded. Similarly, the informal checks on the presidency had also degraded before Trump's inauguration. This article uses Trump's presidency—and his severe limitations as a decision-maker—to highlight the ways in which even a weak leader can affect change by holding a powerful office.

Civil society perspectives on sexual violence in conflict: patriarchy and war strategy in Colombia

4 March 2020 , Volume 96, Number 2

Anne-Kathrin Kreft

In international policy circles, conflict-related sexual violence (CRSV) is commonly viewed as a weapon of war, a framing that researchers have criticized as overly simplistic. Feminist scholars in particular caution that the ‘weapon of war’ framing decontextualizes sexual violence in conflict from the structural factors of gender inequality that underpin its perpetration. In light of these tensions, how do politically relevant local actors perceive the nature and the origins of conflict-related sexual violence? Civil society organizations often actively confront conflict-related sexual violence on the ground. A better understanding of how their perceptions of this violence align or clash with the globally dominant ‘weapon of war’ narratives therefore has important policy implications. Interviews with representatives of Colombian women's organizations and victims' associations reveal that these civil society activists predominantly view conflict-related sexual violence as the result of patriarchal structures. The mobilized women perceive sexual violence as a very gendered violence that exists on a continuum extending through peace, the everyday and war, and which the presence of arms exacerbates. Strategic sexual violence, too, is understood to ultimately have its basis in patriarchal structures. The findings expose a disconnect between the globally dominant ‘weapon of war’ understanding that is decontextualized from structural factors and a local approach to CRSV that establishes clear linkages to societal gender inequality.

Reimagining Trade Rules to Address Climate Change in a Post-Pandemic World

Event participants

Chair: Creon Butler, Director, Global Economy and Finance Programme, Chatham House

This event is part of the Chatham House Global Trade Policy Forum and will take place virtually only.

International trade has a crucial role to play in tackling climate change. The production and transport of goods is a major contributor to green-house gas emissions, as is the delivery of certain cross-border services. At the same time, it looks inevitable that the COVID-19 pandemic will lead to a radical re-think of global supply chains as companies and governments seek to build in greater resilience while at the same time preserving as far as possible the efficiency gains and lower costs that global supply chains generate when operating normally.

Future international trade rules will have a crucial role to play in addressing both challenges; they represent both an opportunity and a risk. If designed well, they could play a very important role in re-enforcing moves towards a more sustainable use of resources, greater overall alignment of economies with the Paris Agreement, and greater economic resilience. But they could also, if poorly designed and implemented, or overly influenced by strategic political considerations, have significant unintended and negative implications. These include: reduced economic efficiency, increased poverty, unnecessary economic decoupling and reduced consensus on the broader mitigation and adaptation measures required to meet the challenge of climate change.

Against this background, a number of key questions arise: In what areas, if any, do we need to modify or adapt key principles underlying the system of global trade rules in order to respond to the twin challenges of responding to climate change and building greater economic resilience?  Which are the most promising/practical areas on which trade policy experts should focus now to re-launch/re-energize discussions on WTO reform, including, for example, dispute settlement? What national economic policies will be needed to complement the development of new/reformed trade disciplines in these areas? How might future political changes, such as a change in the US administration, affect the prospects for and political momentum behind such deliberations? What in any eventuality is the best way to build the required political momentum?
 
This roundtable is convened by the Global Economy and Finance Programme and the US and the Americas Programme and it is part of the Chatham House Global Trade Policy Forum. The event will take place virtually only.

We would like to take this opportunity to thank founding partner AIG and supporting partners Clifford Chance LLP, Diageo plc, and EY for their generous support of the Chatham House Global Trade Policy Forum.

Differing approaches across the hemisphere have had different impacts on presidential popularity and, at least in one case, on democratic institutions and human rights. Yet, even within that diversity, South America’s Southern Cone countries (Argentina, Chile, Paraguay and Uruguay) have shown a sign of solidarity: protecting and facilitating trade flows, sponsoring cross-border research and ensuring citizens’ return to their home countries.    

The response from populist leaders

On the extreme have been the responses of presidents of Brazil, Nicaragua and Mexico, all of whom have ignored the science of the virus and of experts and refused to implement isolation policies.  President Jair Bolsonaro of Brazil fired his health minister, Luis Henrique Mandetta on 16 April for contradicting him and earlier had claimed that the pandemic was a hoax or little more than a ‘measly cold.' 

Meanwhile, Nicaraguan president Daniel Ortega has resisted closing businesses and schools.  After a mysterious 34-day absence, Ortega appeared on television on 15 April reinforcing his refusal to close businesses saying that Nicaraguans must work or they will die and claiming that the virus was ‘imported.’ 

Mexico’s Andres Manuel Lopez Obrador (AMLO) has also resisted the call for strict stay-at-home policies, though with his Deputy Health Minister, Hugo López-Gatell, has closed schools – recently extending the closure to the 1st of June and urging non-essential businesses to close – but focusing primarily on social distancing. 

In contrast to his deputy health minister and Foreign Minister Marcelo Ebrard – who had declared the situation a health emergency on 30th March, later than many neighbouring countries – AMLO has largely attempted to avoid discussion of the pandemic, claiming that in his case he has lucky charms that prevent him from contracting the virus. 

And both Bolsonaro and AMLO have participated in large public rallies, doing all the things that politicians love, shaking hands and hugging babies, and in the case of the former even wiping his nose before embracing an elderly woman.

The Nicaraguan, Brazilian and Mexican presidents make an odd grouping since one (Bosonaro) is considered of the extreme populist right and the others (Ortega and AMLO) of the populist left. What unites them is good old-fashioned populism, a belief in a leader who represents the amorphous popular will and should be unfettered by checks and balances on his power, including something like… science.  

An eclectic group

At the other extreme have been the quick responses by governments in Peru, Argentina, Chile, El Salvador and Colombia which put quarantine measures in place in mid-March. In these cases, governments have even banned outdoor activities and in the case of Peru and Colombia (in the large cities) have imposed alternating days for when women and men can leave the house so as to better control outside movement.  

This too, though, is an eclectic group. It includes a Peronist president Alberto Fernández in Argentina, conservative presidents Sebastian Piñera in Chile and Ivan Duque in Colombia, interim president and relative political neophyte Martin Vizcarra in Peru and outsider president Nayib Bukele in El Salvador. 

El Salvador’s strict quarantine measures have led to rising concerns that Bukele is using the crisis to consolidate personal power, using the national police and the armed forces to enforce the quarantine and ignoring three rulings by the Supreme Court urging the president to end the abuses. In Argentina, Peronist Fernández has shown a surprising commitment to containment even as it hurts his party’s working-class base, not something typically expected of the populist Peronist Party.   

In all of these cases, the quick, strong responses by the presidents shored up their popularity. Peru’s Vizcarra saw his popularity shoot up 35 points in a week to 82 per cent according to surveys taken in March. In late March 2020, Fernández in Argentina saw his approval ratings swell to 79.2 per cent with 94.7 percent of citizens approving of the government’s strict shelter-at-home policies.   Even presidents Piñera and Duque who had struggled with low approval ratings throughout 2019 and saw those numbers sink even lower after the social protests that ended the year have seen their numbers rise.  

According to an 20th April poll, Piñera’s popular approval rating swelled from 13 percent in March 18th at the start of the crisis to 25 per cent by 20th April; while hardly a sweeping popular mandate, even that level was unthinkable only a few months ago when administration was battered by social protests. 

In Colombia, after a series of political missteps and the popular protests, Duque’s popular approval rating had slumped to 26 per cent; by April 2nd, 62 percent of Colombians supported the once-beleaguered president.   (No recent surveys were available for Bukele in El Salvador.)

In contrast, Bolsonaro’s in Brazil has only nudged up.  Before the crisis hit, the president’s popularity had been in steady decline from a high of 49 per cent in January 2019 to 30 per cent by early December 2019. But by the first week in April, in the midst of a crisis in which other presidents saw their approval ratings increase by double digits, after his public disagreements with the health minister, Bolsonaro’s had sunk to 33 per cent while the soon-to-be-fired Mandetta’s stood at 76 per cent.  

AMLO in Mexico has fared no better. The populist leftist scored a high 86 per cent approval rating in February 1, 2019. By March 28, 2020 with concerns over his weak and flippant COVID-19 response and a severe contraction in economic growth, AMLO’s approval rating had sunk 26 points to 60 per cent and his disapproval stood at 37 per cent.    

In the midst of disharmony, coordination

Despite these differences, many countries in the region have shown the solidarity they often speak of but rarely follow in policy or practice. Peru, Chile and other countries have collaborated in repatriating citizens back to their home countries in the midst of the crisis.  

Even the countries of the Southern Cone common market, MERCOSUR, have pulled together on a number of fronts.  The trade bloc had effectively been ruled a dead-man-walking after its failed efforts to integrate Venezuela into the bloc, lowering its standards to let in the petroleum dependent semi-authoritarian government of then President Hugo Chávez. 

Even on the basics of internal cooperation, the block was struggling, unable to coordinate monetary policies and non-tariff trade barriers between the original founding member states, Argentina, Brazil, Paraguay and Uruguay.

The 35-year-old customs union seemed to get a breath a new life with the announcement that it had concluded 20-year-long negotiations with the EU for a free trade deal. Ratification of that deal, however, ran aground on the political differences between the recently elected governments of Bolsonaro in Brazil and the Peronist Fernández in Argentina. 

Bolsonaro refused to attend the Fernández December 2019 inauguration, in protest of the newly elected president’s leftist leanings.  And this was well before their sharply divergent reactions to the COVID-19 virus. 

How surprising then that Mercosur has served as an effective coordination mechanism for these different and once opposed governments. The trade body is collaborating among member states to ensure the repatriation of citizens and has agreed to coordinate to ensure that trade flows, especially of medical supplies, are not interrupted by shutdown measures

Mercosur has even gone one step further than several other bodies have failed to take.  In early April the bloc’s governing body, based in Montevideo, Uruguay created a $16 million (12 million pound) fund to augment country research and assist in the purchase of supplies needed to combat the virus.  

Now if Brazil, Argentina and the others could only coordinate their domestic coronavirus responses and economic policy. In late March Fernández announced he was pulling Argentina out of a possible Mercosur-EU trade deal.

Professor Anita Isaacs, Benjamin R. Collins Professor of Social Sciences, Haverford College
Chair: Dr Christopher Sabatini, Senior Research Fellow for Latin America, US and the Americas Programme, Chatham House

The US government recently announced restrictions on immigration, stating the new measures were necessary due to COVID-19 and the effect the pandemic has had on the US economy. But what is the role of immigrants in the essential official and unofficial services in the COVID-19 stay-at-home era? How is COVID-19 affecting immigration from Central America and Mexico? 

Separately, there have also been instances of outbreaks among detainees in US Immigration and Customs Enforcement centers and claims that immigrants who are returning to Guatemala are spreading the virus. How have US immigration policies affected infection rates in Central America and Mexico and among its citizens?

Arturo Sarukhan, Mexican Ambassador to the US from 2007 - 13, and Anita Isaacs, Benjamin R. Collins Professor of Social Sciences, Haverford College, will join us to discuss the impact COVID-19 is having on migrants.

Dopamine transporter trafficking and Rit2 GTPase: Mechanism of action and in vivo impact [Neurobiology]

Following its evoked release, dopamine (DA) signaling is rapidly terminated by presynaptic reuptake, mediated by the cocaine-sensitive DA transporter (DAT). DAT surface availability is dynamically regulated by endocytic trafficking, and direct protein kinase C (PKC) activation acutely diminishes DAT surface expression by accelerating DAT internalization. Previous cell line studies demonstrated that PKC-stimulated DAT endocytosis requires both Ack1 inactivation, which releases a DAT-specific endocytic brake, and the neuronal GTPase, Rit2, which binds DAT. However, it is unknown whether Rit2 is required for PKC-stimulated DAT endocytosis in DAergic terminals or whether there are region- and/or sex-dependent differences in PKC-stimulated DAT trafficking. Moreover, the mechanisms by which Rit2 controls PKC-stimulated DAT endocytosis are unknown. Here, we directly examined these important questions. Ex vivo studies revealed that PKC activation acutely decreased DAT surface expression selectively in ventral, but not dorsal, striatum. AAV-mediated, conditional Rit2 knockdown in DAergic neurons impacted baseline DAT surface:intracellular distribution in DAergic terminals from female ventral, but not dorsal, striatum. Further, Rit2 was required for PKC-stimulated DAT internalization in both male and female ventral striatum. FRET and surface pulldown studies in cell lines revealed that PKC activation drives DAT-Rit2 surface dissociation and that the DAT N terminus is required for both PKC-mediated DAT-Rit2 dissociation and DAT internalization. Finally, we found that Rit2 and Ack1 independently converge on DAT to facilitate PKC-stimulated DAT endocytosis. Together, our data provide greater insight into mechanisms that mediate PKC-regulated DAT internalization and reveal unexpected region-specific differences in PKC-stimulated DAT trafficking in bona fide DAergic terminals.

G{alpha}q splice variants mediate phototransduction, rhodopsin synthesis, and retinal integrity in Drosophila [Signal Transduction]

Heterotrimeric G proteins mediate a variety of signaling processes by coupling G protein–coupled receptors to intracellular effector molecules. In Drosophila, the Gαq gene encodes several Gαq splice variants, with the Gαq1 isoform protein playing a major role in fly phototransduction. However, Gαq1 null mutant flies still exhibit a residual light response, indicating that other Gαq splice variants or additional Gq α subunits are involved in phototransduction. Here, we isolated a mutant fly with no detectable light responses, decreased rhodopsin (Rh) levels, and rapid retinal degeneration. Using electrophysiological and genetic studies, biochemical assays, immunoblotting, real-time RT-PCR, and EM analysis, we found that mutations in the Gαq gene disrupt light responses and demonstrate that the Gαq3 isoform protein is responsible for the residual light response in Gαq1 null mutants. Moreover, we report that Gαq3 mediates rhodopsin synthesis. Depletion of all Gαq splice variants led to rapid light-dependent retinal degeneration, due to the formation stable Rh1-arrestin 2 (Arr2) complexes. Our findings clarify essential roles of several different Gαq splice variants in phototransduction and retinal integrity in Drosophila and reveal that Gαq3 functions in rhodopsin synthesis.

S-Palmitoylation of the sodium channel Nav1.6 regulates its activity and neuronal excitability [Cell Biology]

S-Palmitoylation is a reversible post-translational lipid modification that dynamically regulates protein functions. Voltage-gated sodium channels are subjected to S-palmitoylation and exhibit altered functions in different S-palmitoylation states. Our aim was to investigate whether and how S-palmitoylation regulates Nav1.6 channel function and to identify S-palmitoylation sites that can potentially be pharmacologically targeted. Acyl-biotin exchange assay showed that Nav1.6 is modified by S-palmitoylation in the mouse brain and in a Nav1.6 stable HEK 293 cell line. Using whole-cell voltage clamp, we discovered that enhancing S-palmitoylation with palmitic acid increases Nav1.6 current, whereas blocking S-palmitoylation with 2-bromopalmitate reduces Nav1.6 current and shifts the steady-state inactivation in the hyperpolarizing direction. Three S-palmitoylation sites (Cys1169, Cys1170, and Cys1978) were identified. These sites differentially modulate distinct Nav1.6 properties. Interestingly, Cys1978 is exclusive to Nav1.6 among all Nav isoforms and is evolutionally conserved in Nav1.6 among most species. Cys1978 S-palmitoylation regulates current amplitude uniquely in Nav1.6. Furthermore, we showed that eliminating S-palmitoylation at specific sites alters Nav1.6-mediated excitability in dorsal root ganglion neurons. Therefore, our study reveals S-palmitoylation as a potential isoform-specific mechanism to modulate Nav activity and neuronal excitability in physiological and diseased conditions.

{alpha}-Synuclein filaments from transgenic mouse and human synucleinopathy-containing brains are maȷor seed-competent species [Molecular Bases of Disease]

Assembled α-synuclein in nerve cells and glial cells is the defining pathological feature of neurodegenerative diseases called synucleinopathies. Seeds of α-synuclein can induce the assembly of monomeric protein. Here, we used sucrose gradient centrifugation and transiently transfected HEK 293T cells to identify the species of α-synuclein from the brains of homozygous, symptomatic mice transgenic for human mutant A53T α-synuclein (line M83) that seed aggregation. The most potent fractions contained Sarkosyl-insoluble assemblies enriched in filaments. We also analyzed six cases of idiopathic Parkinson's disease (PD), one case of familial PD, and six cases of multiple system atrophy (MSA) for their ability to induce α-synuclein aggregation. The MSA samples were more potent than those of idiopathic PD in seeding aggregation. We found that following sucrose gradient centrifugation, the most seed-competent fractions from PD and MSA brains are those that contain Sarkosyl-insoluble α-synuclein. The fractions differed between PD and MSA, consistent with the presence of distinct conformers of assembled α-synuclein in these different samples. We conclude that α-synuclein filaments are the main driving force for amplification and propagation of pathology in synucleinopathies.

Reactive dicarbonyl compounds cause Calcitonin Gene-Related Peptide release and synergize with inflammatory conditions in mouse skin and peritoneum [Molecular Bases of Disease]

The plasmas of diabetic or uremic patients and of those receiving peritoneal dialysis treatment have increased levels of the glucose-derived dicarbonyl metabolites like methylglyoxal (MGO), glyoxal (GO), and 3-deoxyglucosone (3-DG). The elevated dicarbonyl levels can contribute to the development of painful neuropathies. Here, we used stimulated immunoreactive Calcitonin Gene–Related Peptide (iCGRP) release as a measure of nociceptor activation, and we found that each dicarbonyl metabolite induces a concentration-, TRPA1-, and Ca2+-dependent iCGRP release. MGO, GO, and 3-DG were about equally potent in the millimolar range. We hypothesized that another dicarbonyl, 3,4-dideoxyglucosone-3-ene (3,4-DGE), which is present in peritoneal dialysis (PD) solutions after heat sterilization, activates nociceptors. We also showed that at body temperatures 3,4-DGE is formed from 3-DG and that concentrations of 3,4-DGE in the micromolar range effectively induced iCGRP release from isolated murine skin. In a novel preparation of the isolated parietal peritoneum PD fluid or 3,4-DGE alone, at concentrations found in PD solutions, stimulated iCGRP release. We also tested whether inflammatory tissue conditions synergize with dicarbonyls to induce iCGRP release from isolated skin. Application of MGO together with bradykinin or prostaglandin E2 resulted in an overadditive effect on iCGRP release, whereas MGO applied at a pH of 5.2 resulted in reduced release, probably due to an MGO-mediated inhibition of transient receptor potential (TRP) V1 receptors. These results indicate that several reactive dicarbonyls activate nociceptors and potentiate inflammatory mediators. Our findings underline the roles of dicarbonyls and TRPA1 receptors in causing pain during diabetes or renal disease.

Brain manganese and the balance between essential roles and neurotoxicity [Molecular Bases of Disease]

Manganese (Mn) is an essential micronutrient required for the normal development of many organs, including the brain. Although its roles as a cofactor in several enzymes and in maintaining optimal physiology are well-known, the overall biological functions of Mn are rather poorly understood. Alterations in body Mn status are associated with altered neuronal physiology and cognition in humans, and either overexposure or (more rarely) insufficiency can cause neurological dysfunction. The resultant balancing act can be viewed as a hormetic U-shaped relationship for biological Mn status and optimal brain health, with changes in the brain leading to physiological effects throughout the body and vice versa. This review discusses Mn homeostasis, biomarkers, molecular mechanisms of cellular transport, and neuropathological changes associated with disruptions of Mn homeostasis, especially in its excess, and identifies gaps in our understanding of the molecular and biochemical mechanisms underlying Mn homeostasis and neurotoxicity.
