The receptor structures critical for echovirus 1 attachment are contained solely within the VLA-2 I domain, and soluble receptor fragments can prevent infection.
May inform soluble decoy strategies for echovirus 1; leaves open in vivo efficacy and clinical translation.
The isolated I domain of the integrin VLA-2, produced as a bacterial fusion protein, specifically bound echovirus 1 and prevented virus attachment to cells. These results demonstrate that the receptor structures critical for virus attachment are contained solely within the VLA-2 I domain and that soluble receptor fragments are capable of preventing infection.
