Interleukin-10 (cytokine synthesis inhibitory factor) acts in the central nervous system of rats to reduce sleep

Abstract

Interleukin-10 (IL-10), originally designated a cytokine synthesis inhibitory factor, inhibits the synthesis of the pro-inflammatory cytokines IL-1 and tumor necrosis factor by stimulated human and mouse monocytes/macrophages; these cytokines are involved in the regulation of sleep. To determine if IL-10 reduces spontaneous sleep, we injected murine recombinant IL-10 intracerebroventricularly into rats prior to light onset. Non-rapid eye movements sleep was reduced. The behavioral responses to IL-10 were abolished by heat-inactivation of this cytokine. We believe these to be the first observations of central nervous system actions for this cytokine. These results further support the hypothesis that cytokines are involved in the regulation of sleep, and suggest an additional mechanism whereby sleep may be altered in response to an activated immune system.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
