| Research Abstract |
Kawasaki disease (KD) is an idiopathic vasculitis in children. As its coronary sequela could be a risk factor of ischemic heart diseases in young adulthood, elucidation of its pathogenesis is one of the most important issues in cardiovasular medicine. Using Candida albicans water soluble extract (CAWS)-induced mouse model for KD, we got the following results: 1 ) IgM, MBLs and C3-derived peptides deposited in the inflamed vasculature. 2) IgM type autoantibody was increased in response to CAWS-stimulation. 3) the autoantibody recognized some specific endogenous proteins including a mitochondrial enzyme. These findings suggest that some specific infectious stimuli provoke innate humoral immunity to cause sterile vasculitis such as Kawasaki disease.
