Dr. Mehboob Ali Hussain is an associate professor of pediatrics, medicine, and biological chemistry at the Johns Hopkins University School of Medicine. His research focuses on metabolism, with a particular focus on pancreatic beta cell regeneration and pancreatic insulin secretion models. 

Dr. Hussain serves as the director of the Cell Biology Core of Diabetes Research Center at the Johns Hopkins School of Medicine.

His team is currently engaged in research that examines pancreatic beta cell biology and its relevance for the treatment of diabetes mellitus. When there is not enough insulin and more insulin is needed (as in obesity or in juvenile diabetes mellitus), the insulin-producing beta cells in the pancreas ramp up their function and also increase in number by cell division. How these two processes are regulated is poorly understood. The laboratory uses genetic mouse models and state-of-the-art molecular biological techniques to understand these two processes and identify potential drug targets for treating humans with either Type 1 (juvenile) and Type 2 diabetes mellitus

Dr. Hussain earned his M.D. from the University of Zurich Medical School in Switzerland. He completed clinical and research training at the University Hospital in Zurich and completed a residency in medicine at the New York University School of Medicine. Dr. Hussain was a research fellow in molecular endocrinology at Massachusetts General Hospital and Harvard Medical School. Dr. Hussain joined the Johns Hopkins faculty in 2005. more

Research & Publications

Research Summary

Dr. Hussain’s research interest is in the area of diabetes mellitus and pancreatic beta-cell biology. The laboratory effort is directed towards better understanding of the pancreatic beta cell biology and its relevance for the treatment of diabetes mellitus. Their work focuses on the differentiation and regeneration of pancreatic endocrine cells from progenitor/stem cells. In vitro cell culture and in vivo animal models are used to elucidate the molecular mechanisms differentiation of stem cells. These techniques are also being used to identify the extra- and intracellular signals and transcription factors that regulate differentiation pathways of stem cells. A second line of investigation addresses the role of intracellular signals in the function and proliferation of insulin-producing pancreatic beta cells.
