IMMUNOLOGICAL STUDIES OF THE 11S PROTEIN COMPONENT OF THE HUMAN COMPLEMENT SYSTEM [PDF]
The Journal of Experimental Medicine, 1964 Rabbit anticryoprotein and anticomplement antisera recognized a heat-labile antigen in normal human serum. This antigen best fitted the previously described US protein because of its presence in fresh human serum, euglobulin, and purified 11S preparations and its absence in heated serum, R11S, and pseudoglobulin preparations. The 11S hemolytic activity

Biochemical characterization of membrane cofactor protein of the complement system. [PDF]
The Journal of Immunology, 1988 Abstract Membrane cofactor protein (MCP; formerly termed glycoprotein 45-70 to indicate its Mr) of complement is a widely distributed iC3/C3b binding protein with co-factor activity. On human mononuclear cells and cell lines and platelets, MCP is a doublet.

The Kaposi's Sarcoma-associated Herpesvirus Complement Control Protein Mimics Human Molecular Mechanisms for Inhibition of the Complement System [PDF]
Journal of Biological Chemistry, 2004 Kaposi's sarcoma-associated human herpesvirus (KSHV) is thought to cause Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman's disease. Previously, we reported that the KSHV complement control protein (KCP) encoded within the viral genome is a potent regulator of the complement system; it acts both as a cofactor for factor I and ...

Dysregulation of complement system in neuropsychiatric disorders: A mini review
Biomarkers in Neuropsychiatry, 2022 Complement system is one of the most important defense mechanisms of the innate immune system. In addition to their roles in immune regulation, complement proteins are also involved in neurodevelopment and adult brain plasticity. Complement dysregulation

Virus-Encoded Complement Regulators: Current Status
Viruses, 2021 Viruses require a host for replication and survival and hence are subjected to host immunological pressures. The complement system, a crucial first response of the host immune system, is effective in targeting viruses and virus-infected cells, and ...

Membrane Protein Crry Maintains Homeostasis of the Complement System [PDF]
The Journal of Immunology, 2008 AbstractComplement activation is tightly regulated to avoid excessive inflammatory and immune responses. Crry−/− is an embryonic lethal phenotype secondary to the maternal complement alternative pathway (AP) attacking a placenta deficient in this inhibitor.

Staphylococcus aureus proteins Sbi and Efb recruit human plasmin to degrade complement C3 and C3b [PDF]
, 2012 Upon host infection, the human pathogenic microbe Staphylococcus aureus (S. aureus) immediately faces innate immune reactions such as the activated complement system. Here, a novel innate immune evasion strategy of S. aureus is described.
