The lymphotoxin (LT) system has several defined roles in the regulation of immunity as well as vascular and lymphatic biology, however its role in cancer is less understood. Here the authors show that regulatory T cell-derived LTα1β2 promotes LTβ receptor-nonclassical NFκB signaling in tumor cells and lymphatic endothelial cells, accelerating tumor growth and metastasis.
