For example, diffuse large B cell lymphoma (DLBCL), tenosynovial giant cell tumors (TGCT), prostate adenocarcinomas (PRAD), and other types of tumors were positively correlated with infiltration in NK, MAIT, and CD8+ T cells, while thymomas (THYM) were negatively correlated with infiltration in CD4/CD8-naive T cells, CD4/CD8 T cells, T follicular helper (Tfh) cells, and central memory (Figure 4a). This evidence concerns the gene CD8A and testicular germ cell tumor.
