Article Synopsis
  • The GGGGCC hexanucleotide repeat expansion in the C9orf72 gene is identified as a common cause of amyotrophic lateral sclerosis (ALS), leading to motor neuron degeneration and paralysis.
  • A zebrafish model expressing glycine-proline dipeptide repeats (GP DPR) reveals that both gain- and loss-of-function effects contribute to nerve cell damage and autophagy deficits, with poly(GP) levels similar to those found in ALS patient tissues.
  • Potential treatments involving autophagy activators like rapamycin or urolithin A show promise in alleviating motor deficits and offer new therapeutic options for ALS patients by addressing key disease mechanisms.

Vascular inflammation is widely recognized as an important factor in the atherosclerotic process, particularly in terms of plaque development and progression. Conventional tests, such as measuring circulating inflammatory biomarkers, lack the precision to identify specific areas of vascular inflammation. In this context, noninvasive imaging modalities can detect perivascular fat changes, serving as a marker of vascular inflammation.

Arterioscler Thromb Vasc Biol

October 2024

Institut national de la santé et de la recherche médicale (INSERM), EFS (Etablissement français du sang) Grand Est, BPPS (Biologie et pharmacologie des plaquettes sanguines: hémostase, thrombose, transfusion) UMR (Unité mixte de recherche)-S1255, FMTS (Fédération de médecine translationnelle de Strasbourg), Université de Strasbourg, France (E.J.-B., N.R., L.M., C.M., S.M., F.L., B.H., P.H.M.).

Article Synopsis
  • Platelets play a crucial role in stopping bleeding during inflammation, but their behavior can change based on the specific context and the receptors involved, particularly β1 and β3 integrins.
  • In experiments with mice, those lacking β3 integrins showed bleeding in various inflammation models, while those lacking β1 integrins did not, indicating that β3 is more critical for hemostasis.
  • The study concluded that the necessity and interplay between β1 and β3 integrins in managing bleeding during inflammation are influenced by the type of inflammatory scenario encountered.

Background: Pregnancy air pollution exposure (PAPE) has been linked to a wide range of adverse birth and childhood outcomes, but there is a paucity of data on its influence on the placental epigenome, which can regulate the programming of physiological functions and affect child development. This study aimed to investigate the association between prenatal air pollutant exposure concentrations and changes in placental DNA methylation patterns, and to explore the potential windows of susceptibility and sex-specific alterations.

Methods: This multi-site study used three prospective population-based mother-child cohorts: EDEN, PELAGIE, and SEPAGES, originating from four French geographical regions (Nancy, Poitiers, Brittany, and Grenoble).

The most common form of facioscapulohumeral dystrophy (FSHD1) is caused by a partial loss of the D4Z4 macrosatellite repeat array in the subtelomeric region of chromosome 4. Patients with FSHD1 typically carry 1 to 10 D4Z4 repeats, whereas nonaffected individuals have 11 to 150 repeats. The ~150-kilobyte subtelomeric region of the chromosome 10q exhibits a ~99% sequence identity to the 4q, including the D4Z4 array.

It has been known for a long time that epileptic seizures provoke brain neuroinflammation involving the activation of microglial cells. However, the role of these cells in this disease context and the consequences of their inflammatory activation on subsequent neuron network activity remain poorly understood so far. To fill this gap of knowledge and gain a better understanding of the role of microglia in the pathophysiology of epilepsy, we used an established zebrafish Dravet syndrome epilepsy model based on Scn1Lab sodium channel loss-of-function, combined with live microglia and neuronal Ca imaging, local field potential (LFP) recording, and genetic microglia ablation.

Insulin-producing pancreatic β cells play a crucial role in the regulation of glucose homeostasis, and their failure is a key event for diabetes development. Prolonged exposure to palmitate in the presence of elevated glucose levels, termed gluco-lipotoxicity, is known to induce β cell apoptosis. Autophagy has been proposed to be regulated by gluco-lipotoxicity in order to favor β cell survival.

Identifying Newborns with Hypoxic-Ischemic Encephalopathy in Hospital Discharge Data: A Validation Study.

J Pediatr

May 2024

INSERM UMR 1153, Obstetrical, Perinatal and Pediatric Epidemiology Research Team (EPOPé), Center for Epidemiology and Statistics Sorbonne Paris Cité (CRESS), FHU PREMA, Paris Descartes University, Paris, France.

Hospital discharge databases (HDDs) are increasingly used for research on health of newborns. Linkage between a French population-based cohort of newborns with hypoxic-ischemic encephalopathy (HIE) and national HDD showed that the HIE ICD-10 code was not accurately reported. Our results suggest that HDD should not be used for research on neonatal HIE without prior validation of HIE ICD-10 codes.

During the last two decades, the introduction of tyrosine kinase inhibitors (TKIs) to the therapy has changed the natural history of CML but progression into accelerated and blast phase (AP/BP) occurs in 3-5% of cases, especially in patients resistant to several lines of TKIs. In TKI-refractory patients in advanced phases, the only curative option is hematopoietic stem cell transplantation. We and others have shown the relevance of the expression of the Interleukin-2-Receptor α subunit (IL2RA/CD25) as a biomarker of CML progression, suggesting its potential use as a therapeutic target for CAR-based therapies.
