Human peripheral blood monocytes stimulated with LPS were found to release an activity that was cytotoxic for the A375 melanoma. Biochemical and immunological characterization of the activity indicated that IL 1-beta was the cytotoxic agent. Human recombinant IL 1-beta, purified to homogeneity, was directly cytotoxic for A375. Tumor necrosis factor, also released by activated monocytes, was not cytotoxic for the A375 melanoma.
