Abstract/OtherAbstract:
Many viral backbones have been used as gene transfer vectors. However, the efficacy of therapy based on human-derived vectors may be limited by the high incidence of pre-existing humoral and cellular memory immunity. To circumvent some of the clinical disadvantages of vectors derived from common human pathogens, we have used an E1-deleted vector derived from a xenogenic adenovirus, canine adenovirus serotype 2 (CAV-2) to ameliorate neuropathological changes associated with the lysosomal storage disorder, mucopolysaccharidosis type IIIA (MPS IIIA). This presently untreatable condition is caused by N-sulfoglucosamine sulfohydrolase (SGSH) deficiency and is characterized by heparan sulfate accumulation and progressive neurodegeneration. Injection of CAV-SGSH-GFP into the thalamus of adult MPS IIIA mouse brain resulted in short-term gene expression. In contrast, intra-ventricular injection of newborn mice yielded dose-dependent transgene expression which persisted for at least 20-weeks and improved neuropathology. Together, these studies suggest that this E1-deleted CAV-2 vector is capable of mediating regional medium-term gene expression and facilitating improvements in neuropathology in MPS IIIA mice.
