Recently there has been an increase in the global prevalence of metabolic syndrome including obesity, diabetes and fatty liver. Metabolic syndrome also causes a variety of neurologic events such as depression and anxiety. However, the underlying mechanisms remain largely unknown. Maintenance of metabolic homeostasis and the response to nutritional and environmental challenges require the coordination of multiple organs. The central nervous system (CNS) regulates feeding behavior and peripheral organ functions via neuropeptides or neuroendocrine pathways. On the other hand, afferent nerves and secreted proteins transmit metabolic information from peripheral organs to CNS. The disturbance of these processes is an important driving factor for metabolic syndrome and related diseases. Therefore, more research is needed to identify mechanisms underlying the crosstalk between CNS and peripheral organs. Currently, we are trying to use tissue-specific knockout mice and cell line models, combined with various tissue injection of adeno-associated virus strategy to address these issues. These studies will help to understand the molecular mechanisms and pathogenesis of metabolic syndrome and relatedneurological disorders, which will contribute to the discovery of new drug targets for treating these diseases. Specific aims include investigating:
1) the role of CNS in regulating metabolic homeostasis;
2) mechanisms underlying signals from peripheral tissues influencing the CNS;
3) nutrient sensing mechanisms underlying metabolic diseases and neurological disorders.
