CD4 and neoplasm: In patients with KIRC, LPAR2 expression was significantly correlated with tumor purity (R = -0.155, P = 8.49e-04), B cell infiltration (R = 0.168, P = 2.94e-04), CD4 + T cell infiltration (R = 0.242 P = 1.46e-07), neutrophil infiltration (R = 0.197, P = 2.09e-05), and DC infiltration (R = 0.141, P = 2.66e-03) (Fig. 11A) but not with the infiltration of CD8 + T cells and macrophages (Fig. 11A).
