Biomedical Physiology and Immunotherapy integrates biological processes and interactions at the molecular, cellular and organ levels in order to understand how an organism works. Eventually an understandable model of the whole system can be developed. Members of the faculty of the PEMM Biomedical Physiology and Immunotherapy Track conduct research focused on uncovering the relationships and interactions among various parts of a biological system (e.g., gene and protein networks involved in cell signaling, metabolic pathways, organelles, cells, physiological systems, organisms etc.). The experimental approaches employ techniques that span the gamut of basic science disciplines, and range from gene manipulation to studies of the interactions among different tissues and organ systems in whole animals, including humans.
