Article Synopsis
  • The study aimed to analyze if sulfonylurea (SU) therapy affects the cardiovascular benefits of glucagon-like peptide-1 (GLP-1) receptor agonists, specifically exenatide, in a post-hoc analysis of the EXSCEL trial.
  • Using intent-to-treat analyses, researchers looked at the influence of various types of SUs on major adverse cardiovascular events (MACE) in participants taking exenatide.
  • The findings indicated that SU use or type did not significantly alter the cardiovascular outcomes influenced by exenatide, suggesting that choices of SU medication do not need to change to maximize cardiovascular benefits for patients with type 2 diabetes.

Astrocytes at the intersection of ageing, obesity, and neurodegeneration.

Clin Sci (Lond)

April 2024

Department of Clinical and Biomedical Sciences, University of Exeter Medical School, Faculty of Health and Life Sciences, University of Exeter, Exeter, U.K.

Once considered passive cells of the central nervous system (CNS), glia are now known to actively maintain the CNS parenchyma; in recent years, the evidence for glial functions in CNS physiology and pathophysiology has only grown. Astrocytes, a heterogeneous group of glial cells, play key roles in regulating the metabolic and inflammatory landscape of the CNS and have emerged as potential therapeutic targets for a variety of disorders. This review will outline astrocyte functions in the CNS in healthy ageing, obesity, and neurodegeneration, with a focus on the inflammatory responses and mitochondrial function, and will address therapeutic outlooks.

Genetic modifiers of rare variants in monogenic developmental disorder loci.

Nat Genet

May 2024

Department of Clinical and Biomedical Sciences, University of Exeter Medical School, Royal Devon & Exeter Hospital, Exeter, UK.

Article Synopsis
  • Rare damaging genetic variants linked to developmental disorders not only cause major health issues but also lead to milder cognitive and socioeconomic impacts in the general population.
  • Carrying multiple rare variants from a set of dominant developmental disorder genes negatively affects cognitive and socioeconomic traits, but this impact can be somewhat mitigated by a higher educational attainment polygenic score.
  • Individuals with a clinical diagnosis of developmental disorders show a lower educational attainment polygenic score and more severe symptoms compared to those without a diagnosis, indicating that both rare and common genetic variants can influence the expression of these traits.

Allogeneic hematopoietic cell transplantation (HCT) is used to treat many blood-based disorders and malignancies, however it can also result in serious adverse events, such as the development of acute graft-versus-host disease (aGVHD). This study aimed to develop a donor-specific epigenetic classifier to reduce incidence of aGVHD by improving donor selection. Genome-wide DNA methylation was assessed in a discovery cohort of 288 HCT donors selected based on recipient aGVHD outcome; this cohort consisted of 144 cases with aGVHD grades III-IV and 144 controls with no aGVHD.

Roche Pharma Research and Early Development (pRED), Neuroscience and Rare Diseases Discovery and Translational Area, Roche Innovation Center Basel, Basel, Switzerland.

Prasinezumab, a monoclonal antibody that binds aggregated α-synuclein, is being investigated as a potential disease-modifying therapy in early-stage Parkinson's disease. Although in the PASADENA phase 2 study, the primary endpoint (Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) sum of Parts I + II + III) was not met, prasinezumab-treated individuals exhibited slower progression of motor signs than placebo-treated participants (MDS-UPDRS Part III). We report here an exploratory analysis assessing whether prasinezumab showed greater benefits on motor signs progression in prespecified subgroups with faster motor progression.

Recent work has revealed an important role for rare, incompletely penetrant inherited coding variants in neurodevelopmental disorders (NDDs). Additionally, we have previously shown that common variants contribute to risk for rare NDDs. Here, we investigate whether common variants exert their effects by modifying gene expression, using multi-cis-expression quantitative trait loci (cis-eQTL) prediction models.

Unraveling the CLCC1 interactome: Impact of the Asp25Glu variant and its interaction with SigmaR1 at the Mitochondrial-Associated ER Membrane (MAM).

Neurosci Lett

May 2024

University of Exeter Medical School, University of Exeter, Exeter, United Kingdom; Laboratory of Pharmacology, Faculty of Pharmaceutical Science, Tokyo University of Science, Japan. Electronic address:

The endoplasmic reticulum (ER) plays an indispensable role in cellular processes, including maintenance of calcium homeostasis, and protein folding, synthesized and processing. Disruptions in these processes leading to ER stress and the accumulation of misfolded proteins can instigate the unfolded protein response (UPR), culminating in either restoration of balanced proteostasis or apoptosis. A key player in this intricate balance is CLCC1, an ER-resident chloride channel, whose essential role extends to retinal development, regulation of ER stress, and UPR.

June 2024

Division of Cardiovascular Medicine, Radcliffe Department of Medicine, British Heart Foundation (BHF) Centre of Research Excellence, University of Oxford, Headington, Oxford, OX3 7BN, United Kingdom.

Nitric oxide (NO) is a key signalling molecule released by vascular endothelial cells that is essential for vascular health. Low NO bioactivity is associated with cardiovascular diseases, such as hypertension, atherosclerosis, and heart failure and NO donors are a mainstay of drug treatment. However, many NO donors are associated with the development of tolerance and adverse effects, so new formulations for controlled and targeted release of NO would be advantageous.

Pharmacol Res

May 2024

University of Exeter Medical School, University of Exeter, St. Luke's Campus, Exeter EX1 2LU, UK. Electronic address:

Primary mitochondrial diseases (PMD) are amongst the most common inborn errors of metabolism causing fatal outcomes within the first decade of life. With marked heterogeneity in both inheritance patterns and physiological manifestations, these conditions present distinct challenges for targeted drug therapy, where effective therapeutic countermeasures remain elusive within the clinic. Hydrogen sulfide (HS)-based therapeutics may offer a new option for patient treatment, having been proposed as a conserved mitochondrial substrate and post-translational regulator across species, displaying therapeutic effects in age-related mitochondrial dysfunction and neurodegenerative models of mitochondrial disease.
