CD8A and neoplasm: The results demonstrated that the expression level of HSPA4 positively correlated with infiltrating levels of B cells (r = 0.288, p = 5.36e−08), CD8+ T cells (r = 0.132, p = 1.46e−02), CD4+ T cells (r = 0.196, p = 2.48e−04), macrophages (r = 0.301, p = 1.50e−08), neutrophils (r = 0.33, p = 3.13e−10), and DCs (r = 0.205, p = 1.43e−04) in HCC but negatively correlated with tumor purity (r = −0.112, p = 3.8e−02) (Fig. 8).
