Profile
Dr. Ahearn's laboratory is investigating the molecular basis underlying the development of systemic lupus erythematosus (SLE) associated with deficiency of component(s) within the classical pathway of the complement system through studies aimed at clarifying the role of complement-mediated clearance of apoptotic cells and pathogenesis. He is developing a novel assay for diagnosing and monitoring disease activity in SLE and other autoimmune diseases based on the observation that products of complement activation, C4d and C3d, are detected on the surface of erythrocytes and platelets (C4d) of SLE patients at much higher levels and expression of CR1 on erythrocytes is significantly lower in SLE patients than in healthy individuals. Dr. Ahearn is developing both in vitro and in vivo models to dissect the molecular mechanisms through which complement components, influence vascular elasticity and development of premature cardiovascular disease in SLE.
