Fig. 8From: Butyrate inhibits iILC2-mediated lung inflammation via lung-gut axis in chronic obstructive pulmonary disease (COPD)Schematic diagram showing the involvement of nILC2s, iILC2s, intestinal flora and butyrate in AECOPD. Acute exacerbation of the intestinal flora Clostridiaceae in COPD mice decreased butyrate, which ultimately promoted the recruitment of intestinal iILC2 into the lungs and enhanced type 2 cytokines (IL-4 and IL-13), participating in the COPD inflammatory responsesBack to article page
