| abstractText | Tonicity-responsive enhancer binding protein (TonEBP) is a widely expressed transcription factor and is important in the regulation of inflammatory cytokines. Here, we have identified TonEBP expression in the hypothalamus, which is particularly high in proopiomelanocortin (POMC) neurons. TonEBP overexpression stimulates POMC transcription, and TonEBP haploinsufficiency in TonEBP (+/-) mice results in a decrease in hypothalamic POMC expression. TonEBP (+/-) mice show reduced sickness responses, which include anorexia and hyperthermia, that are initially induced by tumor necrosis factor (TNF)-alpha. TonEBP (+/-) mice also show lower levels of TNF-alpha-induced hypothalamic expression of POMC and pro-inflammatory cytokines. These results suggest that TonEBP is an important molecular regulator in the development of inflammatory sickness responses through the control of POMC and pro-inflammatory cytokine expression in the hypothalamus. |
