ITPR2 expression level was positive correlated with infiltrating levels of B cells (r = 0.258, P = 6057e-4), CD8+ T cells (r = 0.449, P = 7.01e-10), macrophages (r = 0.459, P = 2.64e-10), neutrophils (r = 0.345, P = 3.87e-6) and dendritic cells (r =0.378, P = 3.49e-7), while negatively correlated with tumor purity(r = -0.241, P = 1.44e-3). Here, CD8A is linked to neoplasm.
