As for LDHA, the four immunoinhibitors with the greatest correlations included interleukin-10 receptor B (IL10RB, rho =0.412, P < 0.001), indoleamine 2,3-dioxygenase 1 (IDO1, rho =0.154, P < 0.001), CD112(PVRL2, rho =0.090, P = 0.039) and CD160 (rho =0.083, P = 0.055) in ccRCC (Fig. S5). Here, IDO1 is linked to nonpapillary renal cell carcinoma.
