Exposure to simazine also decreased cytokine production by macrophages, such as interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha).

In addition, the production of nitric oxide (NO) and tumor necrosis factor-alpha (TNF-alpha) which have been known to be major effector molecules in macrophage-mediated cytotoxicity was decreased by simazine pretreatment in a dose-dependent manner.

After in vitro exposure of human peripheral blood mononuclear cells from normal donors, the production of all 3 cytokines tested--interferon-gamma (a type 1 cytokine), interleukin-5 (a type 2 cytokine) and tumor necrosis factor-alpha (an inflammatory cytokine)--was impaired by up to 70, 50 and 70% respectively in a concentration-dependent manner in cultures exposed to atrazine (0.03-3 microM in 1% dimethylsulfoxide, DMSO).
Other pesticides also dissolved in DMSO--mecoprop, simazine or MCPA (each up to 1 microM)--or dissolved in phosphate-buffered saline--diuron (up to 1 microM), isoproturon (up to 3 microM), metoxuron (up to 8 microM) or metamitron (up to 80 microM)--showed no concentration-related effects on cytokine production.

To assess the effect of EDCs on the development of infectious disease, we investigated the effect of eighteen possible EDCs on mouse macrophage production of tumor necrosis factor-alpha (TNF-alpha) and nitric oxide (NO) in response to bacterial endotoxin in vitro and ex vivo.
Of chemicals we examined, simazine, nitrofen, and benzyl butyl phthalate inhibited lipopolysaccharide (LPS)-induced TNF-alpha production by mouse macrophage cell line RAW 264 in vitro.
