Dynamic control of the complement system by modulated expression of regulatory proteins [PDF]

open access: yesLaboratory Investigation, 2011
The complement system serves many biological functions, including the eradication of invasive pathogens and the removal of damaged cells and immune-complexes. Uncontrolled complement activation causes injury to host cells, however, so adequate regulation of the system is essential.

Engineering novel complement activity into a pulmonary surfactant protein [PDF]

open access: yes, 2010
Complement neutralizes invading pathogens, stimulates inflammatory and adaptive immune responses, and targets non- or altered-self structures for clearance.

A gammaherpesvirus complement regulatory protein promotes initiation of infection by activation of protein kinase Akt/PKB. [PDF]

open access: yes, 2010
Viruses have evolved to evade the host's complement system. The open reading frames 4 (ORF4) of gammaherpesviruses encode homologs of regulators of complement activation (RCA) proteins, which inhibit complement activation at the level of C3 and C4 ...

Role of the complement system in the tumor microenvironment

open access: yesCancer Cell International, 2019
The complement system has traditionally been considered a component of innate immunity against invading pathogens and “nonself” cells. Recent studies have demonstrated the immunoregulatory functions of complement activation in the tumor microenvironment (

Complement proteins in unexpected places: why we should be excited, not concerned! [version 1; peer review: 2 approved]

open access: yesF1000Research, 2020
The complement system consists of more than 30 plasma as well as cell surface proteins that together constitute a major arm of the immune system. The long-held belief is that most of the complement components are synthesized by hepatocytes in the liver ...

IMMUNOLOGICAL STUDIES OF THE 11S PROTEIN COMPONENT OF THE HUMAN COMPLEMENT SYSTEM [PDF]

open access: yesThe 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

Exposure to the complement C5b-9 complex sensitizes 661W photoreceptor cells to both apoptosis and necroptosis. [PDF]

open access: yes, 2015
The loss of photoreceptors is the defining characteristic of many retinal degenerative diseases, but the mechanisms that regulate photoreceptor cell death are not fully understood.

Precision Medicine in Neurology: The Inspirational Paradigm of Complement Therapeutics

open access: yesPharmaceuticals, 2020
Precision medicine has emerged as a central element of healthcare science. Complement, a component of innate immunity known for centuries, has been implicated in the pathophysiology of numerous incurable neurological diseases, emerging as a potential ...

SARS-CoV-2 Exacerbates COVID-19 Pathology Through Activation of the Complement and Kinin Systems

open access: yesFrontiers in Immunology, 2021
Infection with SARS-CoV-2 triggers the simultaneous activation of innate inflammatory pathways including the complement system and the kallikrein-kinin system (KKS) generating in the process potent vasoactive peptides that contribute to severe acute ...

Evasion Mechanisms Used by Pathogens to Escape the Lectin Complement Pathway

open access: yesFrontiers in Microbiology, 2017
The complement system is a crucial defensive network that protects the host against invading pathogens. It is part of the innate immune system and can be initiated via three pathways: the lectin, classical and alternative activation pathway.
