Lentiviral vector particles comprising a Sindbis virus E2 glycoprotein variant and a lentiviral vector genome comprising a sequence of interest are provided. A lentiviral vector particle comprising: (a) an envelope comprising a Sindbis virus E2 glycoprotein variant; and (b) a lentiviral vector genome comprising a sequence of interest; wherein the E2 glycoprotein variant facilitates infection of dendritic cells by the lentiviral vector particle, and wherein the E2 glycoprotein variant has reduced binding to heparan sulfate compared to a reference sequence (HR strain). |
