We further noticed that short‐term exposure to ADT (PCa‐4) induced cell death co‐occurring with activated CD8+T cells (marked with PRF1HighKLRD1HighGZMBHighZEB2+KLRG1+IL7R−); however, this subset belongs to short‐lived effector T cells. This evidence concerns the gene KLRG1 and posterior cortical atrophy.
