Adeno-associated virus (AAV) has been used to express GFP in a variety of tissues. AAV has a tropism for neurones and we have been using AAV-GFP to determine the anatomical localisation of gene transfer after injection into the hypothalami of Wistar rats. The long term aim is to use this viral vector as a tool for investigating the hypothalamic control of appetite, energy expenditure and pituitary function.Male Wistar rats were anaesthetised and injecte...

Cocaine and amphetamine regulated-transcript (CART) is highly expressed in the hypothalamus and was originally reported to be an endogenous satiety peptide. Intracerebroventricular injection of CART can result in motor abnormalities and recent studies have demonstrated increased food intake after intra-nuclear CART administration. To help clarify the situation CART was over-expressed in the hypothalamus using recombinant adeno-associated virus (rAAV-CART). Recombinant adeno-as...
