X*Y females exhibit steeper reproductive senescence in the African pygmy mouse.

Proc Natl Acad Sci U S A

January 2025

Institut des Sciences de l'Evolution de Montpellier, UMR 5554 (CNRS, Université Montpellier, Institut de recherche pour le développement), Montpellier 34090, France.

A wave of studies has recently emphasized the influence of sex chromosomes on both lifespan and actuarial senescence patterns across vertebrates and invertebrates. Basically, the heterogametic sex (XY males in XX/XY systems or ZW females in ZW/ZZ systems) typically displays a lower lifespan and a steeper rate of actuarial senescence than the homogametic sex. However, whether these effects extend to the senescence patterns of other phenotypic traits or physiological functions is yet to be determined.

Neurochemical Databases: Purpose and Expectations.

ACS Chem Neurosci

January 2025

University of Bordeaux, CNRS, Institut des Neurosciences Intégratives et Cognitives d'Aquitaine INCIA CNRS UMR5287, F-33000 Bordeaux, France.

The exploration of increasingly specific brain structures and their relationships, in more nuanced ways, has facilitated the generation of databases for gene expression, connectivity, cell morphology, and electrophysiology. However, neurochemistry, the study of neurochemical environment and transmission, has not yet warranted a public database, despite the plethora of data published. From our viewpoint, a neurochemical database is overdue and would allow the field of neurochemistry to develop facilitating, standardization and reference values, reproducibility, resource efficiency, preservation and accessibility of raw data, hypothesis development and exploration, and metadata analysis.

A ganglioside-based immune checkpoint enables senescent cells to evade immunosurveillance during aging.

Nat Aging

February 2025

Université Côte d'Azur, Centre National de la Recherche Scientifique (CNRS) UMR7284, Institut National de la Santé et de la Recherche Médicale (INSERM) U1081, Institute for Research on Cancer and Aging, Nice (IRCAN), Nice, France.

Although senescent cells can be eliminated by the immune system, they tend to accumulate with age in various tissues. Here we show that senescent cells can evade immune clearance by natural killer (NK) cells by upregulating the expression of the disialylated ganglioside GD3 at their surface. The increased level of GD3 expression on senescent cells that naturally occurs upon aging in liver, lung, kidney or bones leads to a strong suppression of NK-cell-mediated immunosurveillance.

The Brain Tumor Group (BTG) of the European Organization for Research and Treatment of Cancer (EORTC) conducts academic clinical trials and translational research to improve clinical management of patients with primary and secondary brain tumors. The EORTC BTG has traditionally played an important role in providing evidence and thus advancing the field, albeit with a main focus on radiotherapy and pharmacotherapy in gliomas. Although examples of well-designed neuro-oncological surgical trials can be found, evidence in surgical neuro-oncology predominantly includes data from uncontrolled prospective series or retrospective cohorts.

Prion diseases, or transmissible spongiform encephalopathies (TSEs), are neurodegenerative disorders caused by the accumulation of misfolded conformers (PrP) of the cellular prion protein (PrP). During the pathogenesis, the PrP seeds disseminate in the central nervous system and convert PrP leading to the formation of insoluble assemblies. As for conventional infectious diseases, variations in the clinical manifestation define a specific prion strain which correspond to different PrP structures.
