| Outline of Final Research Achievements |
Hemodialysis is a process of purifying the blood of a person whose kidneys are not working normally. During the hemodialysis, complement factor C3a and C5a which cause atherosclerosis and cardiovascular disease occur by activation between blood and dialyzer. In this study, we mostly aimed to identify specific molecules which mainly trigger the production of C3a and C5a. Proteins absorbed by dialyzer after hemodialysis (n=6) were analyzed by mass spectrometry. Various complement factors including complement factor H, is a member of the regulators of complement activation family, were detected. Our results show that complement regulatory factors may contribute to synthesize the C3a and C5a during hemodialysis.
