Great opportunity! The Uni Vienna has launched a call (APART) for 4-funding for outstanding postdocs from a US institution. The host lab has to nominate by 1 August a candidate for further selection. Anyone interested in our work please contact me by email with CV/motivation letter. Hurry up!

Exclusive: NIH to dismiss dozens of grant reviewers to align with Trump priorities The move would undo years of work, leaving advisory councils understaffed, and without the full expertise needed for reviews.

This story was made possible thanks to NIH staff who reached out. I'm always looking for more sources, message me on Signal (mkozlov.01).

If you hit a paywall, making a free account will open the full story.

Huge thank you 🙏 to my awesome co-first author Abhinav Jain @abhinav1993.bsky.social, all co-authors, the Robert & Arlene Kogod Center on Aging, AFAR @afar.org, and the San Diego NSC @nathanshockcenters.org for all their support! 🙏

➡️ intriguing contribution of TCR avidity in this process – low TCR avidity may select for cells prone to acquire innate/NK features, while high TCR avidity associates with stem-like features and may be lost with aging

➡️ many aging changes are happening and common to many, but not all, EBV-specific T cell populations is a loss of stem-like traits and a gain of lymphocyte innateness = CD8+ T cells become more like NK cells as they age

➡️ no evidence of age-related exhaustion or cellular senescence

➡️ human memory CD8+ T cells specific to different Epstein-Barr virus proteins acquire diverse phenotypes already in young adults

➡️ depending on the antigen specificity, these memory CD8+ T cells follow divergent phenotypic and transcriptional aging trajectories, in older adults

Antigen specificity shapes distinct aging trajectories of memory CD8⁺ T cells - Nature Communications Homeostasis of memory T cells is modulated by each antigen encounter, thereby creating a heterogeneous population preventing precise tracking. Here, the authors use barcode-assisted tracing of Epstein...

I’m excited to share our new T cell aging study published in Nature Communications @natcomms.nature.com !

We show that T cells do not age uniformly but undergo distinct aging trajectories even if they were primed simultaneously early in life.

Ageing is linked to inflammation — but only in the industrialized world Inflammation, thought to be a driver of age-related disease, does not worsen with age in some Indigenous communities.

Thank you, Matt!!

I’m so excited and honored to be part of this incredible community!

Call for Applications! The 32nd Annual NIA Training Course provides intense exposure to current concepts in experimental aging research for a cohort of 15-20 research scientists. Applications are due July 1, 2025. Learn more here: bit.ly/44y6RIY

Fig. 2. Profiling of Human PBMCs Reveals Distinct Immune Subpopulations and Marker Expression Patterns. (a) UMAP plots showing selected marker expression intensities across all cells in the UMAP space to highlight lineage-specific marker distribution. (b) Dot plot of all marker expression across all identified PBMC cell types. Dendrogram highlighted distinct marker-based groupings. (c) UMAP visualization showing 16 distinct clusters with annotated cell types including Naive CD4 and CD8 T cells, central memory CD4 and CD8 T cells (Tcm), effector memory CD8 T cells (Tem), terminally differentiated effector memory CD8 T cells (Temra), mucosal-associated invariant (MAIT) T cells, classical monocytes (cMO), intermediate monocytes (iMO), B cells, NK cells, gamma delta (γδ) T cells (Tgd), conventional dendritic cell (cDC) and plasmacytoid dendritic cell (pDC).

Biological sex matters in brain aging

Biological sex is a key modifier of #aging phenotypes, including #Brain 🧠 aging.
