A potential role for integrins in host cell entry by SARS-CoV-2

Abstract excerpt

• Integrin may act as an alternative receptor for SARS-CoV-2 and could be implicated in its transmission and pathology. • The spike protein of SARS-CoV-2 acquired a RGD motif known to bind integrins. This motif is absent from other coronaviruses. • The integrin-binding motif is present at the surface of the spike protein, close to the ACE2 receptor-binding region. • Integrin binding may be a promising...
