tumor-infiltrating lymphocytes

tu·mor-in·fil·trat·ing lym·pho·cytes (TIL, TILS),

lymphocytes collected from the site of a tumor and exposed to IL-2 in vitro to expand the population. When these cells are reinjected into the tumor-bearing host, they will specifically kill the tumor from which they originated.

Administration of RORgamma agonist-treated T cells to tumor-bearing mice as an adoptive cell therapy resulted in numerous effects, including: extended persistence of cytokine-producing T cells in vivo; increased tumor-infiltrating lymphocytes (TILs); reduced immune suppression as measured by decreased PD-1 expression in TILs; and enhanced presence of long-lasting memory immune cells in the spleen.
