( C ) RT-qPCR was performed to assess the expression of ADRA1D, IL-17A, and RORγt in Th17-polarized CD4⁺ T cells with or without ADRA1D overexpression. ( D ) Western blot was conducted to evaluate the protein expression of ADRA1D, IL-17A, RORγt, IL-17RA, TRAF6, and Act1. ( E ) ELISA was used to measure the levels of IL-6, IL-1β, TNF-α, IL-10, and TGF-β in the culture supernatants. n = 3. *** P < 0.001, **** P < 0.0001. One-way ANOVA followed by Tukey’s post hoc test was used for multiple group comparisons.

Figure Lengend Snippet: ADRA1D Overexpression Attenuates the Metabolic and Immunomodulatory Effects of OST in Vivo. ( A ) Body weight changes were monitored in HFD-fed mice treated with OST. (B) Weights of adipose tissue and liver were measured to assess the effect on organ hypertrophy. ( C ) Serum levels of TG, TC, FFA, ALT, and AST were evaluated by biochemical assays. ( D ) Flow cytometry was performed to assess the proportion of CD4⁺IL-17A⁺ cells in the spleen. ( E ) Immunofluorescence staining of liver tissue was used to detect CD4⁺RORγt⁺ double-positive cell infiltration. ( F ) Immunohistochemistry was performed to evaluate hepatic IL-17A protein expression. ( G ) Western blotting was conducted to assess ADRA1D protein expression in liver tissue. ( H ) Western blot was used to detect the phosphorylation levels of ERK1/2 and PI3K in liver tissue. ( I ) H&E staining of adipose tissue was used to assess adipocyte morphology. (J) Oil red O staining of liver sections was performed to evaluate hepatic lipid deposition. n = 6. ** P < 0.01, **** P < 0.0001. For three or more groups, one-way or two-way analysis of variance (ANOVA) was applied, followed by Tukey’s post hoc test. P < 0.05 was considered statistically significant.
