Abstract

Rheumatic symptoms such as joint inflammation and pain are known features of SARS-CoV-2 infection, though the mechanisms remain unclear. Au and colleagues identified the interaction between the viral spike protein and the endothelin-1 (ET-1) signaling pathway as a cause of osteochondral damage. Their study showed that macitentan, an FDA-approved ET-1 receptor antagonist, reduced joint damage and inflammation in a hamster model, suggesting ET-1 as a potential therapeutic target for viral-induced osteoarthritis (OA).
