Abstract

Objective: Although accumulating evidence supports the hypothesis that immune/inflammatory mechanisms are associated with the pathophysiology of bipolar disorder (BD), data about the profile of chemokines (chemotactic cytokines) and chemokine receptors are still scarce. The current study was designed to evaluate the expression of chemokine receptors on lymphocytes of patients with BD in comparison with controls. Methods: Thirty-three patients with type I BD (N= 21 in euthymia;N= 6 in mania/hypomania;N= 6 in depression) and 22 age- and sex-matched controls were subjected to clinical evaluation and peripheral blood draw. The expression of chemokine receptors CCR3, CCR5, CXCR4, and CXCR3 on CD4+and CD8+lymphocytes was assessed by flow cytometry. Results: Patients with BD had decreased percentage of CD4+CXCR3+(p= 0.024), CD4+CCR3+(p= 0.042), and CD4+CCR5+(0.013) lymphocytes in comparison with controls. The percentage of both CD4+and CD8+lymphocytes expressing the chemokine receptor CXCR4 was similar in patients with BD and controls. Likewise, the percentages of CD8+CXCR3+, CD8+CCR3+, and CD8+CCR5+lymphocytes were similar in patients with BD and controls. Conclusion: Our findings reinforce the hypothesis that immune pathways, especially involving CD4+lymphocytes, are involved in the physiopathology of BD.

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.
