We further observed that there was a significant correlation between TGFβ2 and markers of Tregs and exhausted T cells including CCR8, STAT5B, TGFβ, TIM‐3 (Table 2), indicating that TGFβ2 may play a role in immune escape in gastric cancer, although further work will be needed to confirm the mechanisms underlying such escape. The gene discussed is HAVCR2; the disease is gastric cancer.
