Accumulation of the microtubule-associated protein tau is associated with Alzheimer's disease (AD). In AD brain, tau is abnormally phosphorylated at many sites, and phosphorylation at Ser-262 and Ser-356 plays critical roles in tau accumulation and toxicity. Microtubule affinity–regulating kinase 4 (MARK4) phosphorylates tau at those sites, and a double de novo mutation in the linker region of MARK4, ΔG316E317D, is associated with an elevated risk of AD. However, it remains unclear how this mutation affects phosphorylation, aggregation, and accumulation of tau and tau-induced neurodegeneration. Here, we report that MARK4ΔG316E317D increases the abundance of highly phosphorylated, insoluble tau species and exacerbates neurodegeneration via Ser-262/356–dependent and –independent mechanisms. Using transgenic Drosophila expressing human MARK4 (MARK4wt) or a mutant version of MARK4 (MARK4ΔG316E317D), we found that coexpression of MARK4wt and MARK4ΔG316E317D increased total tau levels and enhanced tau-induced neurodegeneration and that MARK4ΔG316E317D had more potent effects than MARK4wt. Interestingly, the in vitro kinase activities of MARK4wt and MARK4ΔG316E317D were similar. When tau phosphorylation at Ser-262 and Ser-356 was blocked by alanine substitutions, MARK4wt did not promote tau accumulation or exacerbate neurodegeneration, whereas coexpression of MARK4ΔG316E317D did. Both MARK4wt and MARK4ΔG316E317D increased the levels of oligomeric forms of tau; however, only MARK4ΔG316E317D further increased the detergent insolubility of tau in vivo. Together, these findings suggest that MARK4ΔG316E317D increases tau levels and exacerbates tau toxicity via a novel gain-of-function mechanism and that modification in this region of MARK4 may affect disease pathogenesis.

Why the next generation is key to protecting human rights Expert comment LToremark 23 June 2021

Strengthening youth participation in public affairs is essential to building inclusive and democratic societies that respect human rights.

Young people have always been drivers of social and economic reform, and today’s global youth population is more numerous and interconnected than ever before. While they have been at the forefront of civic rights movements in recent years, young people are largely excluded from discussions around human rights norms and how to monitor their protection and defence.

Young people are consistently underrepresented in intergovernmental mechanisms and national dialogues, which not only squanders their potential to contribute to effective solutions but also risks disengagement and disillusionment with multilateralism more broadly, at a time when many are already warning of the fraying of the international liberal order. Although there are actors and initiatives working to lift barriers to youth participation in governance – such as the UN Secretary-General’s Envoy on Youth, Jayathma Wickramanayake, or the UN 2016 Not Too Young To Run campaign – these efforts tend to fall short in effecting real change and rarely translate into institutionalized procedures.

While ‘the youth’ is a heterogenous group, comprising different ages, ethnicities, national identities and interests, their participation in realizing human rights is essential to addressing the current challenges and possibilities of human rights for future generations. This will help foster more effective solutions to rights-related challenges, re-build trust in the international human rights framework among younger demographics and broaden and deepen commitments to human rights across generations.

Human rights policies and the online environment

Young people tend to be more technologically literate than their predecessors and also represent the majority of internet users and social media consumers in many countries. They can therefore play a key role in innovating and imagining rights-based solutions to emerging problems for the human rights framework, such as illegitimate collection of data by governments and companies, microtargeting by online platforms, and the sharing of harmful content online. In many cases, international human rights practices have failed to keep pace with these changes and the challenges they bring.

Younger demographics may also approach these novel human rights issues from different starting points. For example, a UK study found that 30 per cent of 18-24 year-olds were ‘unconcerned’ about data privacy compared with only 12 per cent of those aged 55-64, and it has been shown that younger people tend to be more discerning of fake news compared to older generations. There may be a need for human rights institutions and practitioners to acknowledge and bridge these gaps in perspective and understanding to ensure long-term support for proposed solutions.

International cooperation for human rights protection

It has been suggested that young people have reaped the benefits of previous human rights-based policy reforms and have a strong sense of what rights they are entitled to and why these need to be protected through an international framework. Young people are also generally more supportive of multilateralism compared to their older counterparts, as demonstrated by a 2020 survey by Pew Research Center on global attitudes, which showed that 72 per cent of respondents aged 18-29 stated they have a favourable view of the UN, compared with 58 per cent of respondents aged 50 and older.

At a recent Chatham House workshop, young participants from countries as diverse as Lebanon, Kenya and the United States expressed concern that growing hostility towards globalization threatens to undo progress in human rights standards and multilateralism more broadly, progress that they have seen and benefitted from. The rise of nationalist and populist parties has also seen countries shift their attention inwards, as evidenced by former president Trump’s decision to withdraw the US from the Paris Agreement on climate change, and threats by Brazil’s president, Jair Bolsonaro, to follow suit.

Engaging more actively with younger individuals on global human rights reform will help ensure the long-term relevance of multilateral cooperation as well as domestic buy-in of human rights commitments.

Awareness of the interconnectivity of global problems

Young people’s proficiency on online platforms has enabled greater coordination and knowledge sharing without geographical constraints, allowing young activists – like Greta Thunberg – to inspire global movements and foster online discussions about intersectional solutions to modern-day challenges.

This intersectional and transnational lens will be a vital component of building solutions to politically or historically complex issues and can be leveraged to foster better understanding of competing human rights claims relating to issues such as land re-distribution in South Africa or limitations on freedom of movement during the COVID-19 pandemic. These democratic forums and platforms will ultimately help build a global community committed to and engaged with human rights.

Capturing the next generation’s potential

With these concerns and areas of potential in mind, how can human rights institutions and mechanisms create more meaningful avenues for youth input? 

Recent Chatham House research has suggested that multilateral institutions’ efforts to engage youth has often taken the form of ‘superficial listening’, for example inviting a high-profile youth actor to a one-off event or appointing youth delegates who are not able to participate in formal discussions or mainstream governance forums. While encouraging youth participation in meetings focused on human rights can lead to positive change, tokenism can discourage future engagement and dilute the effectiveness of the forums in question.

Capitalizing on the potential of the next generation can be achieved through integrating youth councils and advisers into national and international human rights policy processes, as well as human rights institutions. A few replicable models are already operational, such as the Y7 and the Y20 delegations – the official youth engagement groups for the G7 and G20 – that advance evidence-based proposals to world leaders ahead of the G7 and G20 summits.

At the domestic level, grassroots youth-led movements can help bridge the gap between local constituencies and international policymakers, with youth activists on the ground helping to implement human rights standards and fighting against the spread of misinformation. Strong local networks and civic spaces are essential for pushing back against human rights abuses, and youth activists should be mobilized to connect the efforts of domestic and international bodies to the real issues on the ground; for example, canvassing grassroots youth networks on domestic and traditional customs before implementing development agendas around women’s rights.

As well as providing insertion points for youth policy actors, human rights institutions must communicate their goals more effectively to younger generations and promote intergenerational and inclusive dialogue, for example by holding virtual consultations that  give access to individuals from different backgrounds. Similarly, they should ask young people about their priorities for human rights reform using regular and accessible surveys or by sharing information on online platforms regularly used by this demographic. This will ensure lasting buy-in from the next generation, essential for the relevance and sustainability of the human rights framework in the years to come.

This piece draws upon insights gathered at a workshop hosted by Chatham House in March 2021, which brought together the Institute’s networks of next generation groups including representatives of the QEII Academy Ambassadors, the Panel of Young Advisers, and the Common Futures Conversations community, as well as young members from the South African Institute of International Affairs.

Climate migration: Ways ahead from the next generation The World Today rsoppelsa.drupal 25 May 2022

Ella Dennis and Mike Higgins talk to young activists seeking solutions as global warming wreaks havoc in sub-Saharan Africa

Africa has the lowest carbon emissions per capita yet the highest rate of temperature increase in the world. Rising levels of desertification, drought and flooding are already forcing millions of Africans to relocate to find more stable livelihoods. 

The continent’s youth will bear the brunt of this climate migration problem. It is estimated that by 2050, Africa will be home to 86 million internal climate migrants.

How is climate migration already affecting sub-Saharan Africa and what frameworks could tackle it? To begin to answer those questions, five young activists from across the region, who are members of Chatham House’s Common Futures Conversations, took part in a panel discussion at the world’s first youth-led Conference on Climate Migration, convened in April by the Alliance for Citizen Engagement, a nonpartisan think tank based in the US. 

The conversation and follow-up discussions focused on a common problem – climate migration brings people into conflict and puts pressure on infrastructure. 

In Kenya, droughts have left 3.5 million people hungry and the chronic flooding of several lakes in the Rift Valley has displaced hundreds of thousands, said Gerald Muchiri, 29, a social scientist from Kenya. One result has been outbreaks of violence between pastoralists such as the Orma people and the farmers of the Pokomo community, said Laura Mukhwana, 33, a PhD student in Kenya. She believes this violence is likely to worsen. ‘Inter-group conflicts will pose even larger security concerns for surrounding communities as climate migration intensifies,’ she said.

Suleman Nuhu, 24, a farmer and veterinary student from Nigeria, said farmer-herder conflicts were his country’s most significant climate-migration issue. The movement of nomadic tribes from the north had affected him personally: ‘Nomads have trespassed on [my family’s] farms many times while moving with their livestock, destroying our crops.’ 

Changes in climate also force people to move from rural to urban areas. Nigeria, for instance, struggles with the so-called ‘Lagos problem’, said Temiloluwa Lawal, 25, a lawyer and researcher from Nigeria. An estimated 22 million people, a number that is rising fast, are crammed into a city smaller than Greater London. While not on the same scale, Zimbabwe experiences comparable challenges, said Tinotenda Dube, 29, a Zimbabwean finance director. Thanks to drought, unemployed rural migrants arriving in cities ‘put excessive pressure on service delivery against a low tax base,’ he said. ‘People, including close family members of mine, are crowded in dilapidated homes because they cannot afford to pay rent for decent housing.’ 

But there is hope, say the activists. Dube believes that affordable housing is an ‘integral component of [tackling] the climate migration crisis’. 

In Zimbabwe, he has developed a low-cost home finance model that, he said, has helped more than 250 low-income households find good-quality accommodation. Alongside this initiative, Dube has co-founded a property and construction company, Solinfra Zimbabwe Private Ltd, to provide low-cost housing. 

Muchiri is taking action in Kenya, founding an NGO called Social Assistance Welfare to tackle public health issues, he said: ‘As climate migration becomes more intense, I expect preventable health issues to increase throughout the region, and thus see Social Assistance Welfare as an important mitigation.’

In Nigeria, Nuhu noted that to help reduce conflict between farmers and herders social-media campaigns are encouraging pastoralists to move from nomadic livestock farming to more efficient intensive systems, using ranching and grazing reserves. ‘As for food security problems, the best mitigation is to reduce reliance on rain-fed agriculture through irrigation schemes,’ he said. 

All five agreed that, in their experience, the youth of sub-Saharan Africa could be better informed about climate migration. But they took encouragement from the fact the young are passionate about tackling issues arising from the broader climate crisis. 

In Kenya, Mukhwana pointed to successful youth projects around agro-forestry and tree-planting. She added that there is ‘a growing movement of urban youth who are advocating for climate justice, such as the Kenyan Youth Environmental Network and Fridays for the Future Kenya’. It was pleasing too, she said, that when the Kenyan government revised its contributions to the Paris Climate Accords it staged a week-long youth conference to include their opinions.

‘Overall, I am quite hopeful about how the youth are mobilizing themselves in Kenya,’ she added.

The cornea is densely innervated, mainly by sensory nerves of the ophthalmic branch of the trigeminal ganglia (TG). These nerves  are important to maintain corneal homeostasis, and nerve damage can lead to a decrease in wound healing, an increase in corneal ulceration and dry eye disease (DED), and neuropathic pain. Pathologies, such as diabetes, aging, viral and bacterial infection, as well as  prolonged use of contact lenses and surgeries to correct vision can produce nerve damage. There are no effective therapies to alleviate DED (a multifunctional disease) and several clinical trials using -3 supplementation show unclear and sometimes negative results. Using animal models of corneal nerve damage, we show that treating corneas with pigment epithelium-derived factor (PEDF) plus docosahexaenoic acid (DHA) increases nerve regeneration, wound healing, and tear secretion. The mechanism involves the activation of a calcium-independent phospholipase A2 (iPLA2) that releases the incorporated DHA from phospholipids and enhances the synthesis of docosanoids neuroprotectin D1 (NPD1) and a new resolvin stereoisomer  RvD6i. NPD1 stimulates the synthesis of brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), and of semaphorin 7A (Sema7A).  RvD6i treatment of injured corneas modulates gene expression in the TG resulting in enhanced neurogenesis; decreased neuropathic pain and increased sensitivity. Taken together, these results represent a promising therapeutic option to re-establish the homeostasis of the cornea.

Smith-Lemli-Opitz Syndrome (SLOS) is a developmental disorder (OMIM #270400) caused by autosomal recessive mutations in the Dhcr7 gene, which encodes the enzyme 3β-hydroxysterol-7 reductase. SLOS patients present clinically with dysmorphology and neurological, behavioral and cognitive defects, with characteristically elevated levels of 7-dehydrocholesterol (7-DHC) in all bodily tissues and fluids. Previous mouse models of SLOS have been hampered by postnatal lethality when Dhcr7 is knocked out globally, while a hypomorphic mouse model showed improvement in the biochemical phenotype with ageing, and did not manifest most other characteristic features of SLOS. We report the generation of a conditional knockout of Dhcr7 (Dhcr7flx/flx), validated by generating a mouse with a liver-specific deletion (Dhcr7L-KO). Phenotypic characterization of liver-specific knockout mice revealed no significant changes in viability, fertility, growth curves, liver architecture, hepatic triglyceride secretion, or parameters of systemic glucose homeostasis. Furthermore, qPCR and RNA-Seq analyses of livers revealed no perturbations in pathways responsible for cholesterol synthesis, either in male or female Dhcr7L-KO mice, suggesting hepatic disruption of post-squalene cholesterol synthesis leads to minimal impact on sterol metabolism in the liver. This validated conditional Dhcr7 knockout model may now allow us to systematically explore the pathophysiology of SLOS, by allowing for temporal, cell and tissue-specific loss of DHCR7.

Lipoprotein (a) [Lp(a)] is a risk factor for CVD and a target of therapy, but Lp(a) measurements are not globally standardized. Commercially available assays generally use polyclonal antibodies that detect multiple sites within the kringle (K)IV₂ repeat region of Lp(a) and may lead to inaccurate assessments of plasma levels. With increasing awareness of Lp(a) as a cardiovascular risk factor and the active clinical development of new potential therapeutic approaches, the broad availability of reagents capable of providing isoform independence of Lp(a) measurements is paramount. To address this issue, we generated a murine monoclonal antibody that binds to only one site on apo(a). A BALB/C mouse was immunized with a truncated version of apo(a) that contained eight total KIV repeats, including only one copy of KIV₂. We generated hybridomas, screened them, and successfully produced a KIV₂-independent monoclonal antibody, named LPA-KIV9. Using a variety of truncated apo(a) constructs to map its binding site, we found that LPA-KIV9 binds to KIV₉ without binding to plasminogen. Fine peptide mapping revealed that LPA-KIV9 bound to the sequence ⁴⁰⁷⁶LETPTVV⁴⁰⁸² on KIV₉. In conclusion, the generation of monoclonal antibody LPA-KIV9 may be a useful reagent in basic research studies and in the clinical application of Lp(a) measurements.

Nutritional supplements that contain curcumin -- a natural anti-inflammatory compound -- may protect the eyes from the development and progression of age-related macular degeneration, a new study suggests.

Neuroinflammation can positively influence axon regeneration following injury in the central nervous system. Inflammation promotes the release of neurotrophic molecules and stimulates intrinsic proregenerative molecular machinery in neurons, but the detailed mechanisms driving this effect are not fully understood. We evaluated how microRNAs are regulated in retinal neurons in response to intraocular inflammation to identify their potential role in axon regeneration. We found that miR-383-5p is downregulated in retinal ganglion cells in response to zymosan-induced intraocular inflammation. MiR-383-5p downregulation in neurons is sufficient to promote axon growth in vitro, and the intravitreal injection of a miR-383-5p inhibitor into the eye promotes axon regeneration following optic nerve crush. MiR-383-5p directly targets ciliary neurotrophic factor (CNTF) receptor components, and miR-383-5p inhibition sensitizes adult retinal neurons to the outgrowth-promoting effects of CNTF. Interestingly, we also demonstrate that CNTF treatment is sufficient to reduce miR-383-5p levels in neurons, constituting a positive-feedback module, whereby initial CNTF treatment reduces miR-383-5p levels, which then disinhibits CNTF receptor components to sensitize neurons to the ligand. Additionally, miR-383-5p inhibition derepresses the mitochondrial antioxidant protein peroxiredoxin-3 (PRDX3) which was required for the proregenerative effects associated with miR-383-5p loss-of-function in vitro. We have thus identified a positive-feedback mechanism that facilitates neuronal CNTF sensitivity in neurons and a new molecular signaling module that promotes inflammation-induced axon regeneration.
