چکیده انگلیسی
Nerve growth factor (NGF) therapy has been proposed to treat cognitive impairments in aged patients including those with Alzheimer's disease. Various viral vectors, including adeno-associated virus serotype 2 (AAV2), have been investigated for their ability to deliver NGF in brain. In this study, hybrid vectors (AAV2/5) consisting of the genome of recombinant AAV2 and the capsid of AAV serotype 5 were evaluated for their ability to deliver NGF and green fluorescent protein (GFP) genes into brain. Compared to AAV2, AAV2/5 consistently led to more septal neurons being transduced with GFP over a wider range of distribution. However, both types of vector provided similar levels of long-term (17 weeks) protection of septal cholinergic neurons from axotomy and led to similar levels of NGF accumulation in this region. These results demonstrate that rAAV-mediated NGF gene delivery is neuroprotective for an extended period of time, but that factors other than transduction efficiency appear to determine transgenic NGF expression in septum.
