Abstract

Rationale It has been suggested that corticosteroid-serotonin interactions are central to the pathophysiology of depression. These interactions have been investigated in healthy and depressed humans, primarily using neuroendocrine techniques.Objectives To review the evidence regarding the nature of these interactions in healthy and depressed humans.Methods Electronic searches were performed for relevant papers, employing MEDLINE and Web of Science. To focus the review, we selected only those articles involving (i) assessment of serotonergic function following experimental manipulation of the HPA axis in healthy volunteers; and (ii) assessment of both serotonergic and HPA axis function in clinically depressed subjects.Results Pre-treatment with hydrocortisone, both acutely and sub-acutely attenuates the GH response to GHRH in healthy subjects. This complicates the interpretation of 5-HT neuroendocrine studies employing GH output as a measure. In depression there is evidence that reduced availability of l-tryptophan impairs HPA axis feedback. There is also evidence that depressed and healthy subjects may adapt differently both to low tryptophan and hypercortisolaemic challenges. There is no consistent evidence of a simple relationship between HPA axis function and 5-HT function in depression.Conclusions The putative reduction in central 5-HT function has not been shown to be a direct consequence of hypercortisolaemia. Rather, the 5-HT system and HPA axis have complex inter-relationships. Challenges to either system, such as stress or reduced dietary tryptophan, may perturb the other and subjects vulnerable to depression may fail to adapt to such challenges.

  • Serotonin is an upstream modulator of stress response system activity through its action on the amygdala and hypothalamus, and serotonergic neurotransmission is reciprocally affected by cortisol.

    “Serotonin is an upstream modulator of SRS activity through its action on the amygdala and hypothalamus; serotonergic neurotransmission, in turn, is reciprocally affected by cortisol (Porter et al., 2004; van Goozen et al., 2007)”

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.
