Differential gene expression analysis of CD103+ CD39+ vs. CD103+ CD39− cells confirmed that, as previously reported for other cancer types, CD103+ CD39+ CD8+ T cells from MSI-H endometrial tumors comprise a recently-activated/exhausted subset expressing a.o. TNFRSF9 and HAVCR2 (encoding for TIM3) (Figure 2A). The gene discussed is TNFRSF9; the disease is endometrium neoplasm.
