Total and CD8+ MAIT cells as well as NM‐CD4+, NM‐CD8+, and DN T cells, but not CD4+ and DN MAIT cells, showed increased fractions of PD‐1‐expressing cells and levels of PD‐1 expression within the tumor microenvironment compared to circulating cells (Figure 2e and f). The gene discussed is CD8A; the disease is neoplasm.
