Association of CD8+ T cells senescence with prior chemotherapy and response to anti-PD-1/PD-L1 therapy: A The senescence of CD8+ T cells, indicated by EMRA, CD57, and granzyme B (GRZB) expression, is analyzed in relation to prior chemotherapy exposure. The data are presented as a proportion of the total CD8+ T cell population. B The frequency of CD57+ EMRA CD8+ T cells (cut-off 10%) is compared based on pre-exposure to chemotherapy. C The proportion of CD57+ EMRA and CD57+ GRZB+ EMRA CD8.+ T cells (cut-off 10%) is shown in relation to treatment response, categorized as progressive disease (PD), partial response (PR), or stable disease (SD)
