Julian L. Ambrus, Jr.
MD
Professor
Jacobs School of Medicine & Biomedical Sciences
Specialty/Research Focus
Autoimmunity; Immunology; Rheumatology
Professional Summary:
My research revolves around IL-14 and its role in immunological memory. Studies delve into 3 areas - vaccination, autoimmunity and lymphoid malignancies. The majority of my current work involves studies examining early events in Sjogren‘s syndrome. We have identified new autoantibodies that occur early in the course of the disease. We are examining mediators involved in the early injury to the salivary and lacrimal glands. We are studying events that result in the transition from the autoimmune disease to lymphoma.
