Effects of antidepressants on the production of cytokines

Abstract

There is now evidence that major depression is associated with an up-regulation of the inflammatory response system (IRS). One of the major factors in this IRS activation is the hyperproduction of pro-inflammatory cytokines. Recently, a number of studies examined whether there is a causative role of these inflammatory mediators in the aetiology of major depression. Studies with animal models and cytokine immune therapy in humans suggest that pro-inflammatory cytokines induce depressive symptomatology. Moreover, these depressive symptoms can be effectively reversed by antidepressant treatment. Thus, it may be suggested that antidepressants suppress pro-inflammatory cytokine production and/or action, resulting in improvement of depressive symptoms. The influence of antidepressants on cytokine production has been examined in culture systems in vitro, and in animal models of depression - in which cytokine production is induced by endotoxin administration. Results suggest that antidepressants of several classes decrease the production of pro-inflammatory cytokines such as interferon-gamma and tumour necrosis factor-alpha, and increase that of interleukin-10, an anti-inflammatory cytokine. Further, the effect of antidepressive treatment on cytokine secretion and on plasma levels of cytokines in depressed patients has been studied. Unfortunately, different approaches to examine cytokine production and different techniques to measure cytokines in plasma are used in these studies. Despite this, current data indicate a normalization of cytokine plasma levels and cytokine production after antidepressant treatment. It is clear, however, that more research is warranted and we strongly argue the need for higher standardization in the methodology used to examine the cytokine network in depressed patients.

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.
