CD8A and cancer: We investigated whether this gene expression linked to immune invasion in different cancer types and figured out that AP1M2 expression levels were positively correlated with the levels of B-cell infiltration in 14 cancers, CD4+ T cell infiltration in 17 cancers, CD8+ T cells in 16 cancers, macrophages in 19 cancers, neutrophils in 19 cancers, and dendritic cells in 19 cancers.
