Abstract
An immunoliposome composition targeted to the alphaV-integrin subunit of integrin receptors comprised of ligand-targeted liposomes bearing at least one targeting-ligand derived from an antibody and having binding specificity for at least one integrin receptor comprising an alpha V subunit including αvβ1, αvβ3 αvβ5, αvβ6, or αvβ8 integrin cell receptors is described. The antibody-derived targeting ligand may be a Fab′ fragment, a scFv, or the like. Binding of the immunoliposome to αv-integrin expressing cells, preferably results in internalization of the immunoliposome for cytoplasmic delivery of a liposome-entrapped agent.
