FASLG and neoplasm: For example, exosomes derived from cancer cells containing FasL [118], TGF-β [119], NKG2D ligand [120], Galectin-9 [121], HSP72 [122] and/or other immunomodulatory factors support the immune escape of tumor cells and induce the differentiation of monocyte cell lines that support the tumor cell phenotype [118].
