Human receptor for C3b/C4b: Complement receptor type I

1987
Publisher Summary Receptor function and protein are shown to reside on cells of the myelomonocytic series, mature B lymphocytes, glomerular podocytes, a small population of T lymphocytes, follicular dendritic cells, and even in plasma. The purification scheme to be described in the chapter has made available amounts of purified CR1 sufficient for ...

Epithelial Deposition of Immunoglobulin G1 and Activated Complement (C3b and Terminal Complement Complex) in Ulcerative Colitis

Gastroenterology, 1990
The epithelial destruction seen in ulcerative colitis remains unexplained. Complement activation has been proposed to be involved, but no definite evidence has been available to this end. In the present study, we examined immunohistochemically ulcerative colitis lesions with monoclonal antibodies to activation neoepitopes in the complement component ...

Two different complement receptors on human lymphocytes. One specific for C3b and one specific for C3b inactivator-cleaved C3b.

The Journal of experimental medicine, 1973
IN THE PRESENT STUDY IT WAS SHOWN THAT NORMAL PERIPHERAL LYMPHOCYTES HAVE TWO DIFFERENT COMPLEMENT RECEPTORS: one for C3b (the immune adherence receptor) and one for C3b subsequent to its cleavage by C3b inactivator. The two receptors are not cross-reactive and were shown by tests with various antisera to be antigenically distinct.

An anti-C3b(i) mAb enhances complement activation, C3b(i) deposition, and killing of CD20+ cells by rituximab

Blood, 2003
AbstractWe investigated deposition of the complement protein fragment C3b and its breakdown products (collectively designated as C3b(i)) on CD20-positive cells treated with rituximab (RTX) in the presence of normal human serum (NHS). Radioimmunoassay (RIA) demonstrates that about 500 000 C3b(i) molecules deposit per cell, and fluorescence microscopy ...

[Erythrocyte complement receptor (C3b) expression in multiple sclerosis].

Neurologia i neurochirurgia polska, 1991
The study was carried out in 121 patients with multiple sclerosis and a control group of 519 healthy individuals. In 13 cases of multiple sclerosis and 12 controls family studies were carried out. Complement receptors (C3bR) on the erythrocytes were demonstrated by the haemagglutination test using human IgG heat-aggregated and guinea pig serum which ...
