Obesity, which is characterized by increased adiposity, has reached epidemic proportions globally. The major focus of my research effort concerns the mechanisms underlying obesity-induced insulin resistance, sterile chronic inflammation, and energy imbalance. Particularly, I’m interested in the crosstalk between innate immune cGAS signaling and metabolic dysfunction. We used different tissue-specific transgenic and/or knockout mouse models as well as cell culture studies to elucidate the key signaling mechanism in the regulation of the metabolic diseases. Better understanding of these key mechanisms will provide important information for the development of novel therapeutic targets for the treatment of obesity and its related diseases.
