We have previously reported (Mol. Cell. Endocrinol. (1994) 101, R31-R35) that the proinflammatory cytokines, tumor necrosis factor-alpha (TNF), interleukin-1 beta (IL-1 beta), and interferon-gamma (IFN-gamma), have a marked inhibitory effect on the expression and activity of type I iodothyronine deiodinase (D1) in FRTL-5 rat thyroid cells, while the anti-inflammatory cytokine, transforming growth factor-beta 1 (TGF-beta 1) had no effect. These three proinflammatory cytokines utilize a number of intracellular second messenger systems including the pathways beginning with activation of sphingomyelinase and phospholipase A2...
