Susan K. Fellner

Susan K. Fellner, MD, is a Professor in the Department of Cell Biology and Physiology at the University of North Carolina School of Medicine, Chapel Hill. Her primary affiliation is as a Primary Faculty member within the university's medical school.

Dr. Fellner holds a BA from Smith College (1958) and an MD from the University of Florida Medical School (1966). Her research focuses on calcium (Ca²⁺) signaling mechanisms in renal vasculature, particularly in isolated afferent arterioles. Key areas include the interplay between cell surface G-protein coupled receptors (e.g., angiotensin II, endothelin) and intracellular pathways like the ADP ribosyl cyclase system, superoxide anions, ryanodine receptors, TRPC cation channels, and voltage-gated Ca²⁺ entry.
