Figure Lengend Snippet: SR2211, the inverse agonist of RORγ, attenuated the sweat secretion and Th17 lymphocyte related inflammatory response in hyperhidrosis mice. Mice were administered with vehicle or SR2211 for one week before the induction of hyperhidrosis, as shown in (A) . The number of black dots were calculated (B) . The number of sweat secretory granules were counted (C) and the concentration of acetylcholine in serum was detected by ELISA (D) . Th17 lymphocyte subpopulations in peripheral blood of the mice were compared (E) . The serum levels of IL-17 (F) and IL-6 (G) were measured by ELISA. Western blotting was used to detect the protein expression of IL-17A in the sweat gland of hyperhidrosis mice (H) . GAPDH was used as a loading control and the expressions were normalized to control (I) . The data were presented with mean ± SD. n = 8 for each group. **p < 0.01, ***p < 0.001 from Brown-Forsythe ANOVA test followed by Dunnett’s T3 multiple comparisons test.

Figure Lengend Snippet: a, Experimental design: adult wt C3H/HeJ mice were fed with HCD for 8 weeks before being injected with K1735-M2 tumor cells. When the tumor volume reached ∼0.80-1.00 cm 3 , typically 20-24 days after tumor cell injection, primary tumors were surgically removed. Twenty-eight days after tumor removal, mice were sacrificed for sample collection and analysis. SR2211 was administered to a first group of mice 10 days before tumor removal (SR2211_PRE). A second group of mice received SR2211 treatment 5 days after tumor removal (SR2211_POST). b, Lung metastatic areas (n=5) in HCD-fed K1735-M2 mice treated with either SR2211 or vehicle control. Representative images are shown. Scale bar, 1mm. c, Lung metastatic areas in NCD- or HCD-fed MN/MCA1 wt mice treated with vehicle, SR2211, anti-PD1, or SR2211 plus anti-PD1 (n=5).
