CD8A and gastric adenocarcinoma: Similarly, there was no such relationship between levels of TGFβ2 and tumour purity in stomach adenocarcinoma (STAD), whereas in this same tumour type, the expression of TGFβ2 was significantly associated with levels of CD8+ T cells (R = .139, P = 7.24e‐03), CD4+T cells (R = .258, P = 5.75e‐07), macrophages (R = .442, P = 3.77e‐19), neutrophils (R = .124, P = 1.68e‐02) and dendritic cells (R = .248, P = 1.29e‐05), although there was no relationship with B cell levels (Figure 3B).
