Abstract: Dexmedetomidine is an α2 adrenergic receptor agonist that has been reported to modulate the polarization of CD4+ T cells. However, the underlying mechanisms by which dexmedetomidine induces T-helper 1 (Th1) cell differentiation remain poorly understood. The aim of this study was to explore the potential mechanisms through which dexmedetomidine can induce Th1 cell differentiation. Purified CD4+ T cells were stimulated with anti-CD3/anti-CD28 and then treated with dexmedetomidine. Flow cytometry analysis was adopted to measure the concentration of Th1 cells. Enzyme-linked immunosorbent assay (ELISA) and real-time quantitative polymerase chain reaction (qPCR) were performed to detect protein levels and mRNA expression, respectively, of IFN-γ and IL-4. Western blotting was used to determine the phosphorylation of signal transducer and activator of transcription 1 (STAT1) and T-bet expression. The Th1 cell subset and IFN-γ levels were elevated in the dexmedetomidine-induced CD4+ T cells. Dexmedetomidine enhanced the phosphorylation of STAT1 and the expression of T-bet in the CD4+ T cells. Atipamezole (an α2 adrenergic antagonist) and fludarabine (a STAT1 inhibitor) reversed the dexmedetomidine-induced Th1 cell differentiation. These results suggested that dexmedetomidine induced Th1 cell differentiation via the STAT1-T-bet signaling pathway.

Dissolving Methods
Please choose the appropriate dissolution scheme according to your animal administration guide.For the following dissolution schemes, clear stock solution should be prepared according to in vitro experiments, and then cosolvent should be added in turn:

in order to ensure the reliability of the experimental results, the clarified stock solution can be properly preserved according to the storage conditions; The working fluid for in vivo experiment is recommended to be prepared now and used on the same day;

The percentage shown in front of the following solvent refers to the volume ratio of the solvent in the final solution; If precipitation or precipitation occurs in the preparation process, it can be assisted by heating and/or ultrasound.
