The Morton Laboratory
The Morton laboratory examines the role of the brain in the regulation of energy balance and glucose metabolism and how defects in this control system may contribute to the development of obesity, insulin resistance and diabetes.

Diabetes is a major health concern that increases the risk of cardiovascular disease and is a leading cause of blindness, leg amputation, and kidney failure. This highlights the need for innovative research to develop and support new approaches to diabetes treatment. Ever since its discovery, research has primarily focused on the pancreatic hormone, insulin in the control of blood glucose levels. This research effort has provided clear evidence linking the development of diabetes to defects in insulin secretion and action. However, growing evidence suggests that the brain also plays an important role in maintaining glycemic control. Thus, when blood glucose deviates from its defended level, the brain, working in tandem with the islet, engages homeostatic responses that return it into the defended range. For example, during conditions of low blood glucose levels (i.e. hypoglycemia), the brain mounts integrated behavioral, autonomic and neuroendocrine responses that restore low blood glucose levels to normal. Conversely, the brain has the inherent capacity to normalize diabetic hyperglycemia in response to either leptin or fibroblast growth factor-1 (FGF1), raising the possibility that the brain is a potential target for the treatment of diabetes. Our overarching goal is to identify the neurocircuits in the brain that mediate this effect and understand how they communicate to peripheral tissues to control blood sugars.
Among ongoing projects in the Morton lab are studies that seek to identify neurocircuits that regulate blood glucose levels during environmental, physiological and homeostatic challenges such as hypoglycemia and cold exposure. To accomplish this, we utilize state-of-the-art neuroscience approaches, including both “optogenetics and DREADD” methodologies to selectively activate or inhibit specific neuronal populations in combination with genetic, molecular biological and immunohistochemical techniques. This research effort is supported by a talented, dedicated research team and we collaborate with colleagues both within the University of Washington, including the laboratory of Michael Schwartz, and around the USA. Overall, our research identifies the brain as a possible new avenue for diabetes drug development.
