LMP1 can also promote cell survival through upregulation of anti-apoptotic proteins including Bcl-2 and A20 to protect infected cancer cells from potentially cytotoxic signals such as Fas ligand (FasL), TNF-related apoptosis-inducing ligand (TRAIL) mediated by cytotoxic T cells (8, 31). Here, TNFSF10 is linked to cancer.
