Through TIMER2.0 (Fig. 8E), we analyzed the relationship between IFNG and the infiltration degree of various T cells (CD8+ T cell, CD4+ T cell, NK T cell, Tregs, γδ T cell, and T follicular helper cell) in the tumor microenvironment, indicating that IFNG was positively correlated with CD8+ T cell infiltration. The gene discussed is IFNG; the disease is neoplasm.
