| Outline of Final Research Achievements |
We studied the effect of PACAP on neuroregeneration and neurogenesis in mouse brain ischemia. We injected intraventricularly or intranasally TSG-6 in normal and PACAP gene deficient mice to study whether neuronal cell death was inhibited or not by use of morphological methods. As a result, it appeared that PACAP inhibited neuronal cell death after brain ischemia not depending on TSG-6 so it may be suggested that PACAP affects rescuing neuronal cell death without the effect of TSG-6 pathway. In our another study to search for the gene or gene product which PACAP may affect on protecting cell death in brain ischemia and spinal cord injury that it stimulated to induce CRMP2 protein, which is known as an axon outgrowth factor. It may be suggested that PACAP affects on stimulating CRMP2 protein to stimulate axon outgrowth in rodents as well as primates and humans and in future PACAP may be used for protecting of neuronal cell death after brain ischemia and/or spinal cord injury.
