pubmed:abstractText
An adeno-associated virus (AAV)-derived construct (pJDT95npy) containing rat neuropeptide Y (NPY) cDNA inserted downstream of endogenous AAV promoters was used to investigate AAV-driven NPY expression in postmitotic neurons in vitro and in the brain. NPY mRNA was expressed in NT2/N and rat brain primary neuronal cultures after transfection. There was a corresponding increase in the number of neurons staining for NPY-like immunoreactivity and an increase in NPY release during depolarization in the primary cultures. Injections of Sendai-virosome encapsulated pJDT95npy into neocortex increased NPY-like immunoreactivity in neurons but not glia indicating that the latter cell type did not have the translational, post-translational or storage capacity to accumulate the peptide. Injections into the rat hypothalamic para-ventricular nucleus increased body weight and food intake for 21 days, though NPY-like immunoreactivity remained elevated for at least 50 days. These studies demonstrate that AAV-derived constructs may be useful for delivering genes into post-mitotic neurons, and that Sendai virosomes are effective for delivering these constructs in vivo.
