EFFECTS OF FOREIGN GENE EXPRESSION IN THE CNS ON AMYGDA-KINDLED RATS

该项目的目标是利用腺嘌呤将基因传递到大鼠脑中

The goal of this project is to deliver genes into rat brain using adeno- associated virus (AAV) vector to quench seizures induced by amygdala kindling. Having shown that the AAV is an efficient gene delivery system in the CNS, and that increased Bax mRNA may be important in the cell loss of hippocampus after seizures, further experiments will be done in the next two steps. First, we will recombine the Bax antisense gene into the AAV vector to see if Bax antisense can block cell death or apoptosis in cultured cells. A second major step will be to deliver Bax antisense into the hippocampus of kindled rats to see if it can prevent the kindled seizures. The AAV gene delivery system can be used to transfer any genes in which we might be interested (i.e., growth factors, CCK, Bax, etc.) into the rat brain. This may have potential value for gene therapy of neurodeg- enerative or mental disorders, and will further neuroscience research.
