CD8A and neoplasm: In order to further characterize the role of EFNA3 expression and TIICs, we analyzed the relationship between the expression of EFNA3 and immune marker genes in different types of immune cells, including CD8+ T cells, T cells (general), B cells, monocytes, tumor-associated macrophages (TAMs), M1 and M2 macrophages, neutrophils, NK cells, DCs, Th1 cells, Th2 cells, follicular T helper cells, Th17 cells, Tregs, and T cell exhaustion.
