Abstract: The present invention discloses a fusion protein comprising a vesicular stomatitis virus envelope glycoprotein (VSVG) extracellular domain or a fragment or an analog thereof linked to a polypeptide comprising an antigen binding domain specific to cluster of differentiation 3 (CD3). The application also discloses pseudotyped viruses comprising the fusion protein and pseudotyped viruses encoding for a chimeric antigen receptor (CAR) or T-cell receptor pseudotyped in which the receptor is expressed under a CD3 promoter. Pseudotyped viruses combining these properties are encompassed as well. The application further discloses use of these pseudotyped viruses and method of producing these pseudotyped viruses.
