The OCA treatment suppressed the serum and cardiac inflammasome levels, reduced the cardiac infiltrated CD3+ T cells, increased the cardiac Treg-represented anti-inflammatory cytokines (IL-10/IL-10R) and improved cardiac inflammation, fibrosis and function [decreased left ventricle (LV) mass and increased fractional shortening (FS)] in NASH-OCA mice. This evidence concerns the gene IL10 and metabolic dysfunction-associated steatohepatitis.
