How senescence-associated beta-gal activity can be used to distinguish phenotypic states within human CD8 effector T cells and predict context-dependent death susceptibility.
Key Takeaways
- Effector memory and EMRA CD8+ T cells show wide heterogeneity in SA-β-Gal activity that defines distinct phenotypic subpopulations.
- SA-β-Gal high effector subsets have different expression of CD27, CD28, CD57, CX3CR1, and granzyme programs compared with low cells.
- Β-Gal high CD8EM and CD8EMRA cells undergo faster stimulation-induced death with higher caspase-3/7 activation.
