Prof. Robert A. Mitchell, MD
Professor in the Department of Surgery and a member of the Division of lmmunotherapy at the University of Louisville.
Dr. Robert Mitchell is a tenured Professor in the Department of Surgery and a member of the Division of Immunotherapy at the University of Louisville. He has joint/associate appointments in the Departments of Microbiology & Immunology and Biochemistry & Molecular Genetics. His research is concentrated on the study of immune tolerance in tumor biology. Specifically, his work focuses on the macrophage migration inhibitory factor (MIF) family of cytokines and their independent and coordinated influences on myeloid lineage-dependent T cell suppressive mechanisms which govern tumor-associated immune evasion and subsequent disease progression. He and his laboratory have developed numerous patented pharmaceutical agents that are designed to treat malignant and nonmalignant diseases and they are currently evaluating whether these compounds have a specific role in governing MIF-dependent mitochondrial homeostasis that dictates myeloid cell immune suppression.
