Study of the melanocortin system including the design and synthesis of peptides and peptidomimetics, molecular pharmacology, in vitro receptor mutagenesis, physiology, and neuroscience to understand the role of the AGRP and melanocortins in obesity and feeding behavior.

Johnson, Richard J., M.D., Joint Professor, (Medicine, Division Chief of Nephrology). His group has examined mechanisms involved in renal progression, including the role of mesangial activation, tubulointerstitial disease, and involvement of the microvasculature. A second major area of research has focused on the hypothesis that essential hypertension may be due to acquired renal injury that causes a defect in sodium handling. He also studies the role of uric acid in renal disease and hypertension, with studies involving both basic and clinical research to investigate the pathogenic mechanisms by which uric acid may have deleterious effects. He also has been involved in international research projects, particularly in Peru, where he has studied the etiology of kidney diseases, including those that develop at high altitude.
