Kawasaki disease (KD) is a paediatric vasculitis whose pathogenesis remains unclear. Based on experimental studies using a mouse model for KD, we report here that proline-rich protein tyrosine kinase 2 (Pyk2) plays a critical role in the onset of KD-like murine vasculitis. The mouse model for KD was
BACKGROUND
Giant cell arteritis (GCA)-a primary vasculitis of medium and large arteries-is associated with vessel wall damage, elastic membrane fragmentation, and vascular remodeling. Proteinases are believed to contribute to pathogenesis by degrading extracellular matrix and causing tissue
A widely advocated hypothesis suggests that polymorphonuclear leukocytes release enzymes at sites of inflammation which in turn cause tissue damage, especially vasculitis. To test this we isolated and grew human endothelial cells and labelled them with chromium-51. Polymorphonuclear leukocytes were
