Cytotoxic activity of BCG-activated macrophages against L929 tumor cells is nitric oxide-dependent.


The tumoricidal activity of activated macrophages has been attributed largely to the release of tumor necrosis factor (TNF), or to the production of reactive oxygen or nitrogen intermediates. The L929 tumor cell line (a murine fibroblast-like cell) when treated with actinomycin D (ActD) has been used to measure TNF alpha cytotoxicity. In the present study… (More)
