CD8A and neoplasm: In addition, by using T-cell depletion, isolation, and adoptive T-cell therapy, it was found that cryo-thermal therapy induced Th1-dominant CD4+ T cells that directly inhibited the growth of tumor cells, promoted the maturation of MDSCs via CD4+ T-cell-derived IFN-γ and enhanced the cytotoxic effector function of NK cells and CD8+ T cells, and promoted the maturation of APCs via cell-cell contact and CD4+ T-cell-derived IFN-γ.
