Research Summary
As a physician-scientist in the Ludwig Center for Cancer Genetics and Therapeutics & Howard Hughes Medical Institute at the Johns Hopkins Sidney Kimmel Comprehensive Cancer Center, Dr. Konig’s research focuses on developing precision immunotherapies for the treatment of rheumatic diseases and cancer. A primary goal of his translational research program is the development of antigen-specific and personalized immunotherapies for autoimmune rheumatic diseases, with the intent to achieve sustained disease remission and functional cure.
Dr. Konig has a long-standing interest in mechanisms of disease initiation and propagation in autoimmune rheumatic and inflammatory disease. His postdoctoral research in the Division of Rheumatology elucidated how specific bacteria may cause loss of immunological tolerance and the development of anti-citrullinated protein antibodies (ACPAs) in rheumatoid arthritis, a hallmark of this autoimmune disease. His work identified Aggregatibacter actinomycetemcomitans as a pathogen that induces hypercitrullination and the release of citrullinated autoantigens from neutrophils during periodontal infection. These mechanistic findings may explain the clinical association of rheumatoid arthritis and gum disease and prove critical to research efforts to prevent the development of rheumatoid arthritis in high-risk individuals with evidence of preclinical autoimmunity.

alpha-1 adrenergic receptor antagonists; doxazosin; prazosin; COVID-19-associated hyperinflammation
Clinical Trials
Dr. Konig is engaged in research studies and clinical trials to investigate whether alpha-1 adrenergic receptor antagonists (e.g., doxazosin, prazosin) can prevent mortality in COVID-19 by disrupting the catecholamine-cytokine feed-forward loop that has been shown to drive dysregulated immune responses in animal models.
