Thus, we surmise that potent MET agonists may find many applications beyond liver disease notably in the large number of patients with acute and chronic kidney damage (Zhou et al, 2013) and chronic lung emphysema (Shigemura et al, 2005) and may well find an urgent application in reducing lung damage and fibrosis in patients suffering from COPD (Chronic obstructive pulmonary disease) or severe COVID-19 (Zuo et al, 2010; George et al, 2020). Here, MET is linked to COVID-19.
