Mariana J Kaplan, MD
Senior Investigator and Branch Chief
Systemic Autoimmunity Branch
Dr. Kaplan’s research has focused on identifying mechanisms of immune dysregulation, organ damage, and premature vascular disease in systemic autoimmunity. More specifically, she investigates how innate immunity (in particular, type I interferons and myeloid cells) promote autoimmune responses and end-organ damage in systemic lupus erythematosus, rheumatoid arthritis, and other systemic autoimmune diseases. Recently, her research has focused on identifying abnormalities of neutrophil subsets and the role of neutrophil extracellular traps (NETs) in systemic autoimmune disorders, both of which may contribute to the development of autoimmune responses and end-organ damage. Dr. Kaplan also has an interest in identifying novel therapeutic targets that may prevent premature vascular damage in systemic autoimmunity, as well as the role of environmental triggers in the induction of autoimmunity. Moreover, she has led clinical trials to identify mechanisms that reduce blood vessel dysfunction and mitigate organ damage in autoimmune and chronic inflammatory disorders.
