Complement Activation
The complement system is the most important biochemical cascade in the blood for the recognition, opsonization, and elimination of foreign materials. To date, the leading causes of death in the United States include cancer, cardiovascular and neurodegenerative diseases, and diabetes. New treatments are urgently needed to treat these devastating diseases and nanotechnology potentially provides n...
متن کاملComplement activation and HLA-B27.
The efficiency of complement activation was studied in sera from HLA-B27 positive and negative subjects (27 with previous yersinia arthritis and 35 controls). Activation of complement with zymosan induced higher mean levels of the anaphylatoxin C3a in HLA-B27 positive sera (mean (SD) 7.40 (1.66) mg/l) than in HLA-B27 negative sera (6.41 (1.79) mg/l). Similarly, higher levels of C3d,g, another C...
متن کاملNanoporesize affects complement activation.
In the present study, we have shown the vast importance of biomaterial nanotexture when evaluating inflammatory response. For the first time in an in vitro whole blood system, we have proven that a small increase in nanoporesize, specifically 180 nm (from 20 to 200 nm), has a huge effect on the complement system. The study was done using nanoporous aluminiumoxide, a material that previously has...
متن کاملActivation of Complement
Activation of the complement system by IgA has been a controversial subject since Ishizaka et al. (1) and South et al. (2) observed that C1 was not fixed by IgA. Lack of complement activation has also been inferred from reports that secretory IgA antibodies were unable to opsonize or promote bacterial killing in the presence of complement (3 6). On the other hand, there is evidence that some co...
متن کاملComplement activation in uveitis.
To determine whether complement is activated in uveitis we have measured plasma levels of C3d, a sensitive indicator of complement activation. Increased levels of C3d were found in 11 of 15 patients with idiopathic uveitis, 13 of whom had circulating immune complexes containing complement components. Since during complement activation potent mediators of inflammation are generated, it is sugges...
