Study Provides Insights Into Diagnosis, Treatment of Rare Immune Disease: NIH Scientists Report Findings From 20 Years of ALPS Research
Chief, Molecular Development of the Immune System Section, LI
Our laboratory investigates the molecular regulation of T lymphocytes, particularly as it relates to immunological tolerance, apoptosis, and autoimmune diseases such as multiple sclerosis, type 1 diabetes mellitus, and similar diseases. We use both molecular biology and cellular immunology techniques to pursue these investigations, with a focus on programs of cell death and survival, including apoptosis, autophagy, and necrosis mechanisms. Our approach has been to use contemporary genomic approaches to discover the molecular basis of new genetic diseases of the immune system that affect activation, tolerance, and homeostasis and to develop novel means of diagnosis and immunomodulation of these diseases. Also, we are attempting to pioneer a means of antigen-specific induction of apoptosis of pathogenic T cells as a means of treating autoimmune disease. Such studies could lead to a better understanding of molecular regulatory mechanisms that are important for human immunological diseases.
Dr. Lenardo graduated with a B.A. from the Johns Hopkins University and an M.D. from Washington University, St. Louis. He performed clinical work in internal medicine and research at the University of Iowa and received postdoctoral training at the Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology. He established an independent research unit in the Laboratory of Immunology in 1989 and became a senior investigator and section chief in 1994. Dr. Lenardo serves on several editorial boards and has given numerous lectures around the world on his work on the molecular regulation of immune homeostasis. His work focuses on lymphocyte apoptosis, autoimmunity, and genomics of the immune system. He was one of the founders of the NIH-Oxford-Cambridge Scholars program for doctoral training and the NIH M.D./Ph.D. partnership program.
