1 Nitrite production was induced in mock-infected or R. prowazekii-infected L929 cell cultures treated with IFN-gamma plus TNF-alpha, but not in mock-infected cultures that were untreated or treated with IFN-gamma or TNF-alpha alone. Nitrites tumor necrosis factor Mus musculus
2 Nitrite production was induced in mock-infected or R. prowazekii-infected L929 cell cultures treated with IFN-gamma plus TNF-alpha, but not in mock-infected cultures that were untreated or treated with IFN-gamma or TNF-alpha alone. Nitrites tumor necrosis factor Mus musculus
3 Nitrite production was also not induced in untreated, R. prowazekii-infected cultures; however, in some instances, it was induced in infected cultures treated with IFN-gamma or TNF-alpha alone. Nitrites tumor necrosis factor Mus musculus
4 Nitrite production was blocked by NGMA or aminoguanidine, and these compounds markedly relieved the synergistic inhibitory effect of IFN-gamma plus TNF-alpha on the growth of strain 83-2P in L929 cells. Nitrites tumor necrosis factor Mus musculus
