Alternative complement pathway activation by C4b deposited during classical pathway activation.

The Journal of Immunology, 1986
Abstract Sheep erythrocytes (E) sensitized with anti-E antibody (A) were reacted with guinea pig C1 (C1gp) and human C4 (C4hu) or guinea pig C4 (C4gp) to prepare EAC1, 4b. Treatment of the EAC1, 4b with a buffer containing EDTA removes C1rgp and C1sgp, resulting in the formation of EAC4b. EAC4b prepared in this way were found to be lysed

Complement receptors (C3b, C4b/C3d) unbalance on CLL lymphocytes.

Bollettino dell'Istituto sieroterapico milanese, 1977
A study of lymphocytes bearing C3b, C4b and C3d complement receptor (CRL) was performed on human peripheral blood from 16 healthy donors and 12 patients affected with Chronic Lymphatic Leukemia (CLL). In the latter group a clear rise of C3dCRL was demonstrated, when compared with immunoadherence receptors bearing lymphocytes.

THE FREQUENCY OF C4B VARIANTS OF COMPLEMENT IN FAMILIAL AND SPORADIC ALZHEIMER DISEASE

Alzheimer Disease & Associated Disorders, 1987
A previous study reported an unexpected increased frequency of the uncommon C4B2 allele of complement in a group of patients with senile dementia of the Alzheimer type. We compared the frequency of various C4B types in 25 patients with familial Alzheimer dementia (AD), 22 patients with sporadic AD, and 360 control individuals.

Allelic distribution of complement components BF, C4A, C4B, and C3 in Psoriasis vulgaris

Immunology Letters, 2002
Psoriasis vulgaris is a multifactorial disease; the strongest association was established with the HLA complex. The actual disease-predisposing gene(s) has not been identified yet, but several genes from this region were examined in addition to HLA-C and -B.
