Complement deficient cases reported in the second half of the last century have been of great help in defining the role of complement in host defence. Surveys of the deficient individuals have been instrumental in the recognition of the clinical consequences of the deficiencies. This review focuses on the analysis of the diseases associated with the deficiencies of the various components and re...
After material has been produced for use as an antigen in a complement fixation test it is necessary to find out if the finished product has any complement-fixing ability in the presence of a serum containing a suitable antibody. Moreover, the proposed antigen must not have any undue anticomplementary property, and the " gap" between its anticomplementary titre and its complement fixing titre m...
Borrelia burgdorferi is a spirochete responsible for Lyme disease, the most commonly occurring vector-borne disease in Europe and North America. The bacterium utilizes a set of proteins, termed complement regulator-acquiring surface proteins (CRASPs), to aid evasion of the human complement system by recruiting and presenting complement regulator factor H on its surface in a manner that mimics h...
The aim of our study is to investigate the effect of immigrants on wages for natives with divergent skill level within one country. Skill level is measured as education level and the purpose is to focus on the level where it according to us is a lack in research, namely the effect on high skilled native-born worker wages. Further, our contribution to the already existing studies may be consider...
The C3-inhibitory domain of Staphylococcus aureus extracellular fibrinogen-binding protein (Efb-C) defines a novel three-helix bundle motif that regulates complement activation. Previous crystallographic studies of Efb-C bound to its cognate subdomain of human C3 (C3d) identified Arg-131 and Asn-138 of Efb-C as key residues for its activity. In order to characterize more completely the physical...
BACKGROUND The aim of the present study was to develop a haemolytic assay for the study of the complement system in dairy goats (Capra aegagrus hircus) and to characterize the major goat complement system proteins. RESULTS The commonly used sheep erythrocyte sensitized with rabbit antibodies were not sensitive to lysis by goat serum, but the combination of human red blood cells (RBC) plus rab...
abstract introduction: thalassemia is the most common hereditary anemia in iran. the aim of this study was to evaluate the humoral immune system and assess the effect of splenectomy on the serum level of immunoglobulins igg, igm, and iga and complement components in patients with major thalassemia. materials and methods: this interventional semi-experimental study (before-after) was performed o...
