In Table 1, the inhibition of immune cell proliferation, apoptotic induction of activated CD8+ T-cells, suppression of natural killer (NK) cell activity, interference with monocyte differentiation, and the promotion of regulatory T-cells (Treg), including the expansion of myeloid-derived suppressor cells (MDSC) are among the effects of tumor-derived exosomes (TEX) on immune cells. The gene discussed is CD8A; the disease is neoplasm.
