Here, we show that hantaviruses bind human alphavbeta3 integrins and that binding maps to the plexin-semaphorin-integrin (PSI) domain present at the apex of inactive, bent, alphavbeta3-integrin structures. Pathogenic hantaviruses [New York-1 virus (NY-1V) and Hantaan virus (HTNV)] bind immobilized beta3 polypeptides containing the PSI domain, and human (but not murine) beta3 polypeptides inhibit hantavirus infectivity. Substitution of human beta3 residues 1-39 for murine beta3 residues directed pathogenic hantavirus infection of nonpermissive CHO cells expressing chimeric alphavbeta3 receptors. Mutation of murine beta3 Asn-39 to Asp-39 present in human beta3 homologues (N39D) permitted hantavirus infection of cells and specified PSI domain residue interactions with pathogenic hantaviruses. In addition, cell-surface expression of alphavbeta3 locked in an inactive bent conformation conferred hantavirus infectivity of CHO cells. Our findings indicate that hantaviruses bind to a unique domain exposed on inactive integrins and, together with prior findings, suggest that this interaction restricts alphavbeta3 functions that regulate vascular permeability. Our findings suggest mechanisms for viruses to direct hemorrhagic or vascular diseases and provide a distinct target for modulating alphavbeta3-integrin functions."xsd:string |
