In the studies reported here, combining KVax with let‐7b miRNA enhanced cytotoxic CD8+ TILs in the TME.[40] By evaluating TILs from tumors treated with the combination of KVax and let‐7b, we indeed observed that this combination significantly increases tumor infiltration by both CD4+ and effector CD8+ T cells, and simultaneously enhances the function of these T cells as reflected in enhanced cytokine production (IFN‐γ and granzyme B). The gene discussed is CD4; the disease is neoplasm.
