Abstract

Rationale The hypothesis that proinflammatory cytokines play a causative role in the pathophysiology of depression has been recently tested by studying the effect of antidepressants on production of endogenous cytokines, and on sickness behavior induced by exogenous cytokines. In this last case, however, the effect of antidepressants has been only studied on the effect of peripherally administered cytokines. Objectives The aim of the present study was to determine whether the antidepressant tianeptine can attenuate both peripheral and central cytokine actions. Methods Rats were injected IP with acute (10 mg/kg) or chronic (10 mg/kg, 2 times/day, 17 days) tianeptine. The effects of this treatment were assessed on the behavioral (social exploration, locomotion) and metabolic (food intake, body weight) alterations induced by peripheral or central administration of the cytokine inducer lipopolysaccharide (LPS) (250 microg/kg IP; 100 ng/rat ICV) or the prototypical proinflammatory cytokine interleukin-1 (IL-1)beta (15 microg/rat IP; 90 ng/rat ICV). Results Chronic, but not acute, treatment with tianeptine attenuated the behavioral signs of sickness behavior induced by peripheral, but not central, LPS or IL-1beta. Conclusions This work, which is the first in vivo study assessing the effect of an antidepressant on centrally induced immune activation, shows a clear dissociation between peripheral and central cytokine effects, and suggests a peripheral site of action of tianeptine.

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • Depressive-like behaviors evoked by bacterial endotoxin administration can be alleviated by antidepressant medication or eliminated almost entirely by pretreatment with cytokine synthesis blockers or cytokine antagonists.

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.
