Summary
Type III hypersensitivity underlies a number of common autoimmune diseases, including rheumatoid arthritis and lupus erythematosus. These diseases are caused by the deposition of immune complexes (IC) and the accumulation of neutrophils within small blood vessels. We will use real time imaging to dissect in space and time the recruitment of neutrophils and IC deposition during type III hypersensitivity reactions in order to better understand the pathogenesis of these conditions.

Summary
Neutrophils play a pivotal role in inflammatory diseases including rheumatoid arthritis (RA). G-CSF is a growth factor that is important to neutrophil survival and function. We have shown that in the absence of G-CSF the incidence and severity of experimental autoimmune arthritis are reduced. We will investigate the mechanisms by which this occurs as well as studying the effects of G-CSF blockade on function and survival of human neutrophils from healthy donors and RA patients.
