To clarify the intracellular killing mechanisms of alveolar macrophages against Mycobacterium avium complex, effects of cytokines on O2- and NO2- production from normal and BCG-induced alveolar macrophages were studied. Intracellular growth of M. avium complex was inhibited in the alveolar macrophages stimulated by TNF, but not IFN. Enhancement of O2- production by normal alveolar macrophages stimulated by cytokines, was associated with the inhibition of intracellular growth of M. avium complex. However, when NO2- production by the alveolar macrophages was enhanced by the stimulating of IFN or IFN+TNF, in the presence L-arginine in the culture medium, their defense activity against M. avium complex decreased.

UI MeSH Term Description Entries
D007372 Interferons Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions. Interferon
D008297 Male Males
D009162 Mycobacterium avium A bacterium causing tuberculosis in domestic fowl and other birds. In pigs, it may cause localized and sometimes disseminated disease. The organism occurs occasionally in sheep and cattle. It should be distinguished from the M. avium complex, which infects primarily humans.
D011919 Rats, Inbred Strains Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.

D002478 Cells, Cultured Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others. Cultured Cells,Cell, Cultured,Cultured Cell
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014409 Tumor Necrosis Factor-alpha Serum glycoprotein produced by activated MACROPHAGES and other mammalian MONONUCLEAR LEUKOCYTES. It has necrotizing activity against tumor cell lines and increases ability to reject tumor transplants. Also known as TNF-alpha, it is only 30% homologous to TNF-beta (LYMPHOTOXIN), but they share TNF RECEPTORS.
