We aimed to evaluate the efficacy of VSV-G pseudotyped, defective HIV-1 based lentiviral vectors for the neonatal transfer of therapeutic genes following systemic administration in Sandhoff mouse pups. Despite transgene expression in mouse brains, these animals presented with significant exacerbation and acceleration of the disease neurological phenotype. We observed an increase and acceleration in the presence of MHC-II and CD45+ cells in their brains, along with neuroinflammation, but not in control heterozygous or wild type littermates that also received the same treatment.
