Stephen Desiderio, M.D., Ph.D.
Stephen Vincent Desiderio, M.D., Ph.D.
Director, Institute for Basic Biomedical Sciences
Professor of Molecular Biology and Genetics
Research Interests: Genomic plasticity; DNA recombination; immune development; lymphoid malignancies
Dr. Stephen Desiderio is a professor of molecular biology and genetics at the Johns Hopkins University School of Medicine. His research focuses on the molecular and genetic mechanisms underlying immune system development. Dr. Desiderio serves as the director of the Institute for Basic Biomedical Sciences and director of the immunobiology program at the Institute of Cell Engineering (ICE).
Dr. Desiderio’s research team has made numerous contributions to our understanding of how immunity develops in health and disease. Their studies have shed light on the relationship between genetic rearrangement—the process by which immune diversity is generated—and the development of leukemia. They have discovered key elements of the triggers that turn on immune responses, and most recently have focused on the signals that instruct stem cells to become cells of the immune system.
Dr. Desiderio received his undergraduate degree in biology and Russian from Haverford College. He earned his Ph.D. and M.D. from the Johns Hopkins University School of Medicine. He completed a postdoctoral fellowship at the Massachusetts Institute of Technology. Dr. Desiderio joined the Johns Hopkins faculty in 1984.
From 1984 to 2004, Dr. Desiderio was an investigator of the Howard Hughes Medical Institute. From 1992 to 1999, he was director of the M.D.-Ph.D. program at the Johns Hopkins School of Medicine.
Dr. Desiderio is a member of several professional societies and has been honored by election to the Association of American Physicians and the American Society for Clinical Investigation. He is a member of the Johns Hopkins Kimmel Cancer Center and serves on the editorial board of the Journal of Molecular Medicine. In 2007, the governor appointed him to the Maryland Life Sciences Advisory Board.

Research & Publications
Dr. Desiderio's research focuses on the molecular and genetic mechanisms responsible for development of the immune system. His research has shed light on how the immune system is able to respond to a spectacularly diverse set of invaders. His team’s studies have helped explain the relationship between genetic rearrangement—the process by which immune diversity is generated—and the development of leukemia.
The team has also discovered key elements of the triggers that turn on immune responses, and most recently has turned its attention to signals that instruct stem cells to become cells of the immune system.
The Desiderio lab is interested in the molecular and genetic mechanisms responsible for development of the immune system. Among the most spectacular examples of genomic plasticity are the processes that generate immunologic diversity, including V(D)J recombination. V(D)J recombination, which builds antigen receptor genes from discrete gene segments, shares mechanistic features with transposition and, as a potential source of DNA damage, is subject to tight control. One control mechanism, identified in this laboratory, restricts V(D)J recombination to a specific time in cell cycle through the periodic destruction of the V(D)J recombinase. Using a combination of genetics and biochemistry, our group has defined this process in detail. By constructing specific knock-in mutant mice, we have gone on to show that this mechanism protects against the development of lymphoid cancers and their associated chromosomal translocations. More recently, we have begun to study how V(D)J recombination is controlled at the level of chromatin modification, which may govern accessibility of particular loci to the recombinase.
A related interest is how immune cells respond to environmental cues. Activation of immune cells requires a balance between benefit and risk, and is tightly regulated. Some signals activate immune cells while others block responsiveness—a process called anergy. These signaling mechanisms share common features, including activation of kinases, mobilization of calcium and combinatorial regulation of transcription. We have recently uncovered a novel way in which calcium is regulated in response to antigen receptor stimulation and are now testing whether this mechanism contributes to the decision between activation and anergy.
