Abstract

The effect of interferon-gamma (IFN-gamma) priming of murine peritoneal macrophages on the activation to tumouricidal state by cisplatin, lipopolysaccharide (LPS)-IL-1 and TNF was investigated. Cisplatin-, LPS-, IL-1- or TNF-treated IFN-gamma-primed macrophages showed significantly enhanced tumouricidal activity and binding to tumour cells, compared with unprimed treated or untreated macrophages. Macrophages treated with cisplatin, LPS, IL-1 and TNF produced released and membrane-associated IL-1 and TNF activity which was significantly enhanced after priming with IFN-gamma. These observations suggest the use of IFN-gamma along with these biological response modifiers in designing immunotherapeutic protocols for treatment of malignancy.
