Core Tip

Core Tip: This letter to the editor adds to the ongoing conversation regarding the involvement of angiotensin-converting enzyme 2 (ACE2) in liver fibrosis from the perspective of its effect on the renin-angiotensin system (RAS). The major highlight of this letter is the discussion of the role of ACE2 in regulating liver fibrosis through RAS beyond the pathway studied in the article titled ‘Angiotensin-converting enzyme 2 improves liver fibrosis in mice by regulating autophagy of hepatic stellate cells’.
