We focused on the relationship between YTHDF2 and marker genes of various types of immune cells [CD8+ T cells, monocytes, T cells (general), M1 and M2 macrophages, B cells, neutrophils, tumor-associated macrophages (TAMs), natural killer cells, AND DCs] in LIHC in GEPIA and TIMER databases. The gene discussed is CD8A; the disease is neoplasm.
