Fig. 6From: Butyrate inhibits iILC2-mediated lung inflammation via lung-gut axis in chronic obstructive pulmonary disease (COPD)Butyrate inhibits the inflammatory transformation of ILC2 cells in vitro. Protein expression levels of Arg1, KLRG1 and IL-17RB were determined by Western blot analysis. Representative and quantitate Western blot results of Arg1, KLRG1 and IL-17RB in each group were shown. *P < 0.05, **P < 0.01 and ***P < 0.001 (n = 5)Back to article page
