Microinjection of interleukin-1 into brain: Separation of sleep and fever responses

Walter, James S., Meyers, Paul, Krueger, James M.·1989·Physiology & Behavior

Abstract

Interleukin-1 (IL1) and muramyl peptides are somnogenic, pyrogenic, immune response modifiers, Their central nervous system loci of action with respect to sleep and body temperature in rabbits were examined in this study using microinjection techniques. Unilateral microinjection of IL1 into various basal forebrain or brain stem sites resulted in elevated colonic temperatures (Tc), but the duration of slow-wave sleep (SWS) was unchanged compared to results obtained after control injections. Injection of IL1 into posterior hypothalamic areas failed to elicit either sleep or temperature responses. In contrast to these results, injection of either IL1 or muramyl dipeptide into the Aqueduct of Sylvius was followed by enhanced SWS and Tc. These results show that IL1-induced sleep and fever responses can be separated. Somnogenic sites of action for IL1 and muramyl peptides remain unknown.

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.
