We bred Hoxc8SN∆ mice with a Cre-dependent line (Gt(ROSA)26SorCAG-loxp-STOP-loxp-rabies-G-IRES-TVA mice, henceforth referred to as RGT) expressing two rabies helper proteins: TVA, an avian-specific receptor protein, which permits infection to rabies virus pseudotyped with EnvA, and a rabies glycoprotein, which allows transsynaptic transfer of the virus, both produced in sensory neurons following recombination using the PLAT::Cre line (Figure 6a). This evidence concerns the gene ART4 and infection.
