title: Mycoplasma fermentans (incognitus strain) induces TNF alpha and IL-1 production by human monocytes and murine macrophages.
abstract: We have demonstrated that Mycoplasma fermentans (incognitus strain), as well as M. fermentans KL4, PG 18 and IM 1 strains have the ability to activate human peripheral blood monocytes and murine macrophages of two inbred strains to secrete a high level of tumor necrosis factor alpha (TNF alpha) in a dose-dependent manner. Secretion of interleukin-1 (IL-1) was also stimulated following the incubation of human monocytes with the organism. We suggest that cytokine secretion following infection with M. fermentans (incognitus strain) that was detected in AIDS patients may contribute to the pathological manifestations, including cachexia, in this disease.
