IL17A and Cirrhosis: Serum IL-17 protein and mRNA levels were significantly higher in the four CHB-related conditions than in controls (P < 0.001). Patients with cirrhosis exhibited the highest IL-17 concentrations in the serum and IL-17 mRNA in PBMCs. In addition, the levels of IL-17 in the liver tissues was higher in patients with cirrhosis than in those with CHB; and higher in this last than in HBsAg carriers (P < 0.01, for both)
