| Research Abstract |
In this project, we were focusing on impaired Very Low Density Lipoprotein (VLDL) lipid fraction in serum of individuals with autism. Then, we examined the serum levels of fatty acid composition, autistic animal models based on the lipid profile, imaging analyze and a novel therapy method of autism by using the autistic animal model. To identify causal fatty acid of VLDL-specific lipid profile in autism, we analyzed fatty acid composition by GC-MS, which resulted in impairment of some fatty acids including omega-6. Next, we identified that CD38KO mice showed impairment of VLDL fraction and omega-6 fatty acid like autistic human subject, and found that feeding challenge of omega-6 fatty acid could rescue impairment of social recognition behavior in CD38KO mice immediately after birth. In VLDL Receptor transgenic rat (VLDLR-Tg), we examined behavior test and found that the rat showed hyperactivity and an entire impairment of arachidonic acid distribution in tissues of VLDLR-Tg.
