Michael J. Lenardo

Career

Following graduation, Lenardo pursued an internship in internal medicine at the University of Iowa Hospitals and Clinics. Subsequently, he was accepted into a fellowship program for oncology research at the University of Iowa's Division of Hematology-Oncology. He carried out molecular biology research in the laboratory of Dr. John Donelson, whose postdoctoral work involved contributions to British biochemist and Nobel Laureate Frederick Sanger's second Nobel Prize for DNA sequencing. In Donelson's laboratory, Lenardo was introduced to advanced molecular techniques, including DNA manipulation and sequencing, which encouraged him to pursue molecular research rather than clinical work.

After the fellowship, Lenardo began postdoctoral training at the newly opened Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology. He conducted research in molecular biology of mammalian systems and gene regulation under the mentorship of Nobel laureates David Baltimore and Philip Sharp. His postdoctoral training was productive and involved developing the functional assay for the newly described NF-kB binding complex, providing first evidence of the role of NF-kB in innate immunity, and co-discovering the Oct4 nuclear factor with Louis M. Staudt, among other contributions. Following the completion of his postdoctoral fellowship, he became an independent principal investigator at NIAID, National Institutes of Health.

National Institutes of Health

In 1989, Lenardo established an independent research section in the Laboratory of Immunology at NIAID, later becoming a senior investigator and section chief. He was named a NIH Distinguished Investigator in 2019, a title reserved only for the top 2-3% of investigators across all 27 institutes and centers at NIH.

Lenardo has published over 250 scholarly works and holds a number of medical patents. His work investigates human genetic immunodeficiencies through direct clinical research informed by a range of contemporary molecular, biochemical, and immunological approaches. This has resulted in the discovery of fundamental principles of cellular homeostasis involving previously unidentified molecules, including Fas, Caspase 8, Caspase 10, PI-3 kinase p110, CTLA-4 and its regulator LRBA, CD55, and the MagT1 magnesium transporter. As a result of Lenardo's expansive approach, his laboratory has been able to define the first human genetic disease related to each of these molecules, including Autoimmune Lymphoproliferative Syndrome, Caspase-8 deficiency syndrome, PASLI disease, XMEN disease, and most recently CHAI and LATIAE disease.

Lenardo's work reveals how these molecules control the homeostasis of both immune and non-immune cell types. In so doing, it has illuminated the origins and mechanics of various underlying immunological and genetic disease processes, together with concepts for successful treatments. His lab's 2017 identification of CD55 deficiency (which they named CHAPLE disease) led to the discovery of a safe and highly effective long-term treatment for a previously incurable, extremely debilitating and progressive disease. His discoveries have been found to be broadly applicable to common diseases such as cancer.

Lenardo has served on editorial boards for the European Journal of Immunology, the Journal of Experimental Medicine, Science Magazine, Magnesium Research, and Biology Direct. He is an adjunct professor of pathology at the University of Pennsylvania School of Medicine, and a Life Visiting Fellow at Clare Hall College Cambridge University. Lenardo has been a strong proponent of mentorship for emerging young scientists at the National Institutes of Health. He has been a member of the Board of Trustees of The Johns Hopkins University (1977–1981), is a member of the American Association for the Advancement of Science, elected AAAS Fellow 2009, the American Association of Immunologists, the American Association of Physicians, Federation of Clinical Immunology Societies, the Clinical Immunology Society, the European Society of Immunodeficiencies, and the American Society of Human Genetics.

He has founded or co-founded several joint research programs, including the NIH-Oxford-Cambridge Scholars Program (OxCam), the NIH-University of Pennsylvania Immunology Graduate Partnership Program, the NIH-Marshall Scholars, the NIH-Rhodes Scholars, the National M.D./Ph.D. Partnership Training Program, and the NIH-Institut Pasteur Infectious Disease and Immunology Program.

Music

Lenardo is a member of The Affordable Rock 'n' Roll Act, a band composed of NIH physicians, scientists, and researchers, including NIH Director Francis Collins. Lenardo sings and plays guitar. The band has performed at the Library of Congress, National Building Museum, and several NIH events. Of performing with the band, Lenardo has stated, "I find that music—both listening and performing—unleashes creativity and optimism, which helps my scientific work on these devastating diseases."
