Dr. Trapecar is an assistant professor of medicine in the Division of Endocrinology, Diabetes and Metabolism in the Johns Hopkins University School of Medicine. As a trained immunologist and bioengineer, he is using innovative human-on-a-chip technologies to gain better understanding of how fundamental disruption in tissue-tissue and tissue-immune crosstalk leads to the early emergence of autoimmune and neurodegenerative disorders such as inflammatory bowel disease, autoimmune diseases of the liver and Parkinson’s disease. These remain some of the biggest challenges of our time.

Metabolic and inflammatory disorders such as metabolic syndrome, autoimmune and neurodegenerative diseases are increasing at alarming rates, with little progress made in untangling their causal connection or mitigation of mortality. Emerging human multiorgan microphysiological systems (MPSs), in combination with multiomics and systems biology, offer new and exciting possibilities to provide clarity in metabolic and inflammatory diseases through controlled interaction of multiple MPSs as well as components of the innate and adaptive immune system.
MPSs are reductionist in vitro models comprising multiple cell types, specialized microenvironments, and perfusion, that capture salient features of in vivo organ behavior. We are focused on identifying causation in gut-liver-brain immunometabolic pathologies and explore how disruption of tissue-immune homeostasis leads to the emergence of metabolic diseases. While this approach might yield tangible targets in disease prevention and treatment, it will also contribute to our understanding of humoral physiology of the gut-liver-brain axis, the role of innate and adaptive immune cells for tissue regeneration, and susceptibility of the axis to metabolic perturbation.
