The laboratory of Dr Domingos focuses on neuroimmune mechanisms underlying obesity. Using optogenetics and multiphoton microscopy, among other tools, the laboratory of Dr Domingos has recently discovered a direct connection between adipocytes and the sympathetic nervous system (SNS) (Cell, 2015). Moreover, they showed that this SNS neuro-adipose junction mediates fat mass reduction (Cell, 2015, Nature Comm. 2017). Thus direct and targeted pharmacologic activation of sympathetic inputs to adipose tissues could represent a novel strategy for the induction of fat loss and a new anti-obesity therapy that would circumvent the challenges of drug delivery to the brain. More recently, the Domingos lab identified a molecular mechanism by which a specialized population of immune cells regulates the output of sympathetic neurons, and that is critical in obesity (Nature Medicine, in press).  Howard Hughes Medical Institute, the Welcome Trust, the Human Frontiers Science Program, the European Molecular Biology Organization, and the Gulbenkian Foundation fund the laboratory of Dr Domingos. She has undergraduate training in mathematics, doctoral training in neurobiology mentored by Prof. Dr Leslie Vosshall and postdoctoral training in metabolism mentored by Prof. Dr Jeffrey Friedman, both at the Rockefeller University.
