abstractText | Interleukin (IL)-1 and tumor necrosis factor (TNF) promote slow-wave sleep (SWS), whereas IL-10 inhibits the synthesis of IL-1 and TNF and promotes waking. We evaluated the impact of endogenous IL-10 on sleep-wake behavior by studying mice that lack a functional IL-10 gene. Under baseline conditions, C57BL/6-IL-10 knockout (KO) mice spent more time in SWS during the dark phase of the light-dark cycle than did genetically intact C57BL/6 mice. The two strains of mice showed generally comparable responses to treatment with IL-1, IL-10, or influenza virus, but differed in their responses to lipopolysaccharide (LPS). In IL-10 KO mice, LPS induced an initial transient increase and a subsequent prolonged decrease in SWS, as well as profound hypothermia. These responses were not observed in LPS-treated C57BL/6 mice. These data demonstrate that in the absence of endogenous IL-10, spontaneous SWS is increased and the impact of LPS on vigilance states is altered. Collectively, these observations support a role for IL-10 in sleep regulation and provide further evidence for the involvement of cytokines in the regulation of sleep. |
