BSG and pulmonary fibrosis: Previous studies revealed that CD147‐spike protein is a universal route for SARS‐CoV‐2 infection in host cells.[273, 274] A recent study revealed that CD147 is a major modulator of SARS‐CoV‐2‐induced fibroblast activation.[275] Exploration of the underlying mechanisms is of great importance for the early intervention in SARS‐CoV‐2‐induced pulmonary fibrosis.
