Background: The presence of anti-neutrophil cytoplasmic antibodies (ANCA) in Wegeners granulomatosis (WG), implicate the neutrophil as a key effector cell. Previous studies have reported elevated neutrophil counts in the lung although the determinants of neutrophil chemotaxis in the WG lung are unknown. Methods: BALF cell counts, myeloperoxidase (MPO) and chemokines were measured in 27 patient...
OBJECTIVES Inappropriate activation of neutrophils plays a pathological role in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). The aim of this study was to investigate the functions of semaphorin 4D (SEMA4D) in regulation of neutrophil activation, and its involvement in AAV pathogenesis. METHODS Serum levels of soluble SEMA4D were evaluated by ELISA. Blood cell-surfac...
What drives human beings to classify? It seems as if it is within our nature to do so. Clinical classification systems for the systemic vasculitides were composed a long time ago, and they are constantly being revised and altered. The histopathological features of many diseases are so diverse that classification is called for. The histopathological classification for anti-neutrophil cytoplasmic...
The reports of a newborn who developed glomerulonephritis and pulmonary hemorrhage after transplacental transfer of anti-neutrophil cytoplasmic antibody (ANCA) IgG with specificity for myeloperoxidase (MPO) is compelling clinical evidence that ANCA are pathogenic. In vitro studies indicate that ANCA activate cytokine-primed neutrophils and monocytes through both direct Fab'2 binding and Fc rece...
