Ischemic neuronal death proceeds with a complex series of pathophysiological events in the neurons. Recent evidence has shown that some significant portions of neuronal death following ischemia result from suicide-like phenomena similar to apoptosis. This is supported by appearance of TUNEL positive neurons and by typical EM images in the process of delayed neuronal death after transient forebrain ischemia as well as focal brain ischemia. If ischemic neuronal death and apoptosis share the common pathway, regulation of gene expression might rescue neuronal death. Recently, adeno-associated virus (AAV) has been developed as a non-pathogenic vector for gene therapy. Because AAV has the characteristic of high affinity to the neurons, it is advantageous for targeting neuronal disease. We introduced bcl-2, an inhibitor of apoptosis, to AAV and injected the bcl-2-AAV to CA1 pyramidal neurons in the gerbil after ischemia. We found that overexpression of Bcl-2 effectively protected the post-ischemic neuronal death. Moreover, injection of bcl-2-AAV was effective even one hour after ischemic insult. Our results raise the possibility that induction of bcl-2-AAV is useful for gene therapy to rescue postischemic neuronal death.
