Jonathan Lyons, M.D.

Assistant Clinical Investigator
Genetics and Pathogenesis of Allergy Section

Major Areas of Research

  • To investigate the consequences of altered glycosylation in atopy and allergic inflammation
  • To study the structural variation, altered expression, and function of  the glycoprotein tryptase, a mediator released by mast cells and involved in allergic reactions
  • To develop novel targeted therapeutic approaches for individuals with severe allergy and mast cell-associated disorders

Working in the Milner lab since 2014, Dr. Lyons has been involved in the identification of novel genetic causes for allergic inflammation and immune dysregulation. These include phosphoglucomutase 3 (PGM3) deficiency, an autosomal recessive congenital disorder of glycosylation that leads to a complex hyper-IgE phenotype, and tryptasemia, a variably penetrant disorder associated with dominantly inherited elevations in basal serum tryptase. Deciphering how changes in glycosylation may lead to atopy and immune dysregulation and affect allergic reactions is currently a major area of focus. A second area of focus is on the role that isoforms of the glycoprotein tryptase may play on influencing clinical phenotypes and allergic reactions.

Jonathan Lyons received his undergraduate education at Pomona College and Jesus College, Cambridge, United Kingdon, where he spent two terms. He graduated with a B.A. in chemistry from Pomona College in 2003 and received an M.D. from the University of Southern California in 2007. Dr. Lyons completed residency training in internal medicine at the University of California, San Diego, in 2010, remaining an additional year as a chief medical resident. He concluded his formal medical training in 2014 at NIAID as a clinical fellow in allergy and immunology. Following completion of a fellowship, he was selected for the NIAID Transition Program in Clinical Research and is currently an assistant clinical investigator in the Laboratory of Allergic Diseases. Dr. Lyons is board certified in internal medicine and allergy/immunology, a member of the Clinical Immunology Society, and a member of the American Academy of Allergy, Asthma & Immunology, where he serves on the Genetics, Molecular Biology, and Epidemiology Committee. He is an associate investigator on several clinical protocols and the principle investigator on a protocol to provide sugar supplementation to patients with glycosylation defects and immunologic disease.
