Abstract

Tumor Infiltrating Lymphocyte (TIL) cells transformed with exogenous DNA encoding tumor necrosis factor (TNF) prohormone variants are disclosed. Among such variants are the TNF .gamma. sig construct, which facilitates expression of the mature TNF polypeptide, and the noncleavable cytotoxic prohormone variants TNF.DELTA.(1.fwdarw.12) and TNF(1+12). The transformed TIL cells are useful in antitumor therapy.
