Interleukin-1 mediates the behavioral hyperalgesia produced by lithium chloride and endotoxin

Maier, Steven F., Wiertelak, Eric P., Martin, David, Watkins, Linda R.·1993·Brain Research

Abstract

The sickness-inducing agents lithium chloride (LiCl) and lipopolysaccharide (LPS) produce a long-lasting facilitation of the nociceptive tailflick reflex. Many of the behavioral and physiological changes produced by illness are mediated by interleukin-1 (IL-1) released from monocytes stimulated by the pathogenic substance. Monocytes also produce an IL-1 receptor antagonist (IL-1ra) which has been sequenced and cloned. The present experiments report that IL-1 can itself produce hyperalgesia as assessed by tailflick to radiant heat, and that recombinant IL-1ra blocks the hyperalgesia produced by LiCl and LPS.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Peripheral lipopolysaccharide in rodents increases pro-inflammatory cytokine expression and causes marked hyperalgesia that is abolished by an IL-1 receptor antagonist or a TNFα antagonist.

    “Lipopolysaccharide administered peripherally in rodents results in enhanced pro-inflammatory cytokine expression and marked hyperalgesia that is abolished by administration of an IL-1 receptor antagonist”

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.
