Gzmk+ t cells a hallmark of immune ageing
WebJun 15, 2024 · Using T cell receptor repertoire data, we found that CD8 GzmK + GzmB + T cells are clonally expanded in synovial tissues and maintain their granzyme expression and overall cell state in blood, suggesting that they are enriched in tissue but also circulate. WebSystematic understanding of immune aging on a whole-body scale is currently lacking. We characterized age-associated alterations in immune cells across multiple mouse organs using single-cell RNA and antigen receptor sequencing and flow cytometry-based validation. We defined organ-specific and common immune alterations and identified a …
