Similarly, in a study conducted in non-small cell lung cancer (NSCLC), EMT markers were associated with reduced tumor infiltration of CD4+ and CD8+ T cells, increased expression of immunosuppressive cytokines such as interleukin (IL)-10 and TGF-β, as well as overexpression of inhibitory immune checkpoint molecules such as cytotoxic T-lymphocyte antigen (CTLA)-4 and T-cell immunoglobulin and mucin domain-containing (TIM)-3 [10]. This evidence concerns the gene CD8A and neoplasm.
