Gloria Preston's research explores evidence of pathogenic effects for antineutrophil cytoplasmic autoantibodies (ANCA), most notably those with antimyeloperoxidase or antiproteinase-3 specificity, in small-vessel vasculitides (Wegener's granulomatosis, Churg-Strauss syndrome, and microscopic polyangiitis). The disease process is thought to involve complex interactions between genetic and environmental factors leading to a humoral autoimmune response against neutrophilic components. Preston's work investigates potential pathomechanistic explanations of ANCA-associated diseases. Her research specifically questions the origin of autoantibodies and how environmental exposures contribute: do the autoantibody/granulocyte interactions cause pathogenic changes in granulocyte functions, including changes in gene expression profiles and what factors are primary in the genesis of resultant endothelial lesions of the vascular endothelium.
