Abstract
IL 1 can exhibit dichotomous effects in the sense that it is cytotoxic for certain cells, although growth promoting for other cells. Because IL 1 is growth promoting for astrocytes, but cytotoxic for melanoma cells, the current investigation evaluated the effect of IL 1 upon astrocytomas. The human astrocytoma U373 was found to incorporate [3H]thymidine after exposure to recombinant human IL 1 alpha and IL 1 beta and murine IL 1 alpha. Surprisingly, U373 also incorporated [3H]thymidine after exposure to recombinant TNF. The response of the U373 to IL 1 may be used as a simple and sensitive assay for IL 1.
