CD8A and cervical carcinoma: To investigate the immune inhibitory landscape of tumor-infiltrating CD8+ T cells, we analyzed the expression levels of multiple inhibitory receptors in CD8+ T cells isolated from the peripheral blood mononuclear cells (PBMCs) of 37 treatment-naïve cervical cancer patients and compared them to CD8+ T cells from tumor-infiltrating lymphocytes (TILs) obtained from 10 cervical tumor biopsies.
