Abstract

Evidence indicates that there is an emerging tendency towards autoimmunity occuring in major depressive disorder (MDD). The aim of our study is to investigate the mechanism of autoimmune process in MDD from a novel insight of Th17 cells, which have been identified as the significant activators of autoimmunity. We included 40 patients with MDD and 30 healthy control subjects. An indirect immunofluorescence test was used for the detection of serum antinuclear antibodies (ANA), and revealed that the patient group was positive more frequently than the control group. By flow cytometric analysis, depressed subjects revealed a significant increase in peripheral Th17 cell number, and an obvious decrease in T-reg cell number, showing an imbalance of Th17/Treg ratio compared to healthy controls. We also found a higher level of RORγt (retinoic acid-related orphan receptor-γt, the specific transcription factor of Th17 cell) mRNA expression in peripheral blood lymphocytes by RT-PCR and serum concentration of IL-17 by ELISA in patients. In conclusion, our study showed a potential role of Th17 cells in the autoimmune process in MDD patients, thus contributing to the existing evidence of autoimmune inclination in MDD.

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.
