Research Abstract |
We had previously found the certain components of H. pylori involved in development of H. pylori associated-ITP through the event which the bacterial component binds to platelet. In this study, we attempted to seek the bacterial component binds to platelet using western blotting with IP and LC-MS/ MS for analyzing the participation of Helicobacter pylori infection in ACS. Eventually, an outer membrane protein of H. pylori(HP-OMP) was identified among 11 candidate bacterial proteins followed by western blotting(IP) with all 11 His-fusion candidate proteins prepared. The platelet aggregation experiment demonstrated that the HP-OMP could definitely aggregate platelets via binding to surface of the platelet. Furthermore, the antibody specific to HP-OMP(anti-HP-OMP) was made with rabbit immunization.
