The tumor barrier comprised of nonantigenic stromal cells may contribute to the failure of tumor rejection. The tumor-necrosis factor superfamily member LIGHT (also known as TNFSF-14) is a ligand of stromal cell-expressed lymphotoxin-β receptor and T cell-expressed herpes viral entry mediator (HVEM). Here we show that forced expression of LIGHT in the tumor environment induces a massive infiltration of naive T lymphocytes that correlates with an upregulation of both chemokine production and expression of adhesion molecules. Activation of these infiltrating T cells, possibly through HVEM, leads to the rejection of established, highly progressive tumors at local and distal sites. Our study indicates that targeting the tumor barrier may be an effective strategy for cancer immunotherapy.
