Complement Receptors and Cell Associated Complement Components

Immunological Communications, 1977
Membrane receptors for activated complement components are widely distributed amongst tissue cells of most mammalian species. Common amongst these are receptors for C3b which mediate many of the biological functions of C3. In addition, the genetic control of certain complement components is linked to the genes which code for the major ...

Complement receptors and phagocytosis

Current Opinion in Immunology, 1991
Current understanding of the molecular mechanisms involved in regulating the phagocytic function of monocytes, macrophages and polymorphonuclear leukocytes is summarized, giving emphasis to the role of the phagocyte integrins of the CD11/CD18 family. New data relating to the hypotheses that optimal function of these receptors is a property of activated

Complement Receptors in Neutrophils

Critical Reviews™ in Immunology, 1995
Human neutrophils contain numerous intracellular granules and vesicles that are exocytosed in a hierarchic manner on stimulation of the neutrophil with inflammatory mediators. Secretory vesicles are mobilized completely to the plasma membrane when neutrophils are stimulated with inflammatory mediators in nanomolar concentrations. There is evidence that

Complement receptor structure and function

Immunology Today, 1985
Membrane complement receptors (CRs) are now recognized as important cell-bound components of the complement system and research into the structure and function of complement receptors is one of the main thrusts of current complement research.

Assays for Membrane Complement Receptors

Current Protocols in Immunology, 1994
AbstractLeukocytes express several types of receptors for activated products of the complement (C) system. This unit describes assays for a subset of these receptors: those specific for fixed fragments of C3 (CR1, CR2, CR3, and CR4). Although the assays have been designed for tests of human C receptors, they can often be carried out with rodent (e.g ...

Macrophage phagocytosis of virulent but not attenuated strains of Mycobacterium tuberculosis is mediated by mannose receptors in addition to complement receptors.

Journal of Immunology, 1993
We have examined macrophage receptors that mediate phagocytosis of virulent strains (Erdman and H37Rv) and an attenuated strain (H37Ra) of the intracellular pathogen, Mycobacterium tuberculosis.

Complement Receptors in HIV Infection

Current Molecular Medicine, 2002
Similar to other pathogens, HIV can directly activate the complement pathway even in the absence of antibodies. During and after seroconversion, HIV-specific antibodies enhance the activation of complement and increase deposition of complement fragments on virions dramatically.

Complement factors and their receptors

Immunopharmacology, 1997
In summary, recent advances in molecular cloning of anaphylatoxins and the anaphylatoxin receptors add new dimensions to our investigations and understanding of the molecular mechanisms involved in anaphylatoxin action. Combining knowledge accumulated from peptide modeling of the ligands with mutagenesis studies of these ligands and their receptors ...

Complement Receptor Type 1

1992
This review will focus on the complement receptor type 1 (CR1, CD35) expressed by erythrocytes and will cover its structure, molecular biology, and function as a membrane inhibitor of complement activation. The CR1 present on phagocytic cells and lymphocytes has similar functions in regulation of complement activation and serves as a receptor ...
