Outline of Final Research Achievements |
KD samples elicited proinflammatory cytokine responses from human coronary artery endothelial cells(HCAECs). By LC-MS analysis of KD serum samples collected at 3 different periods,we detected a variety of KD-specific molecules in the lipophilic fractions. Serum KD-specific molecules showed m/z and MS/MS fragmentation patterns almost identical to those of MAMPs obtained from the biofilms formed in vitro (common MAMPs from Bacillus cereus, Yersinia pseudotuberculosis and Staphylococcus aureus) at the 1st study period,and from the biofilms formed in vivo (common MAMPs from Bacillus cereus, Bacillus subtilis/Bacillus cereus/Yersinia pseudotuberculosis and Staphylococcus aureus) at the 2nd and 3rd periods. The biofilm extracts from Bacillus cereus, Bacillus subtilis, Yersinia pseudotuberculosis and Staphylococcus aureus also induced proinflammatory cytokines by HCAECs. By the experiments with IgG affinity chromatography,some of these serum KD-specific molecules bound to IgG.
