Moreover, the expression levels of STIL were positively associated with the infiltration levels of B cells (r = 0.442, P = 7.43e−18), CD8+ T cells (r = 0.333, P = 2.63e−10), CD4 + T cells (r = 0.445, P = 3.80e−18), Macrophages (r = 0.524, P = 1.90e−25), Neutrophils (r = 0.452, P = 8.21e−19), DCs (r = 0.511, P = 5.02e−24) in HCC tissues (Fig. 10A). Here, CD8A is linked to hepatocellular carcinoma.
