Research Interests

Dr. Virella’s research is focused on the investigation of the role of autoimmune and inflammatory processes in the pathogenesis of human atherosclerosis. His lab has established unique protocols for the isolation and characterization of human antibodies to modified lipoproteins, the definition of lipoprotein modification involved in autoimmune reactions, and the biological properties of antigen-antibody complexes prepared with human modified LDL and human purified antibodies to modified LDL. The sum of the data generated in collaboration with Dr. Maria Lopes-Virella supports a pathogenic role for the autoimmune response to modified lipoproteins. Currently we are investigating parameters that may have a modulatory effect on the consequences of autoantibody formation against modified LDL, such as the ration of IgG vs. IgM antibodies and on the definition of immune complex-mediated pathogenic mechanisms responsible for the development of diabetic nephropathy..
