Lectin pathway proteins of the complement system in normotensive pregnancy and pre‐eclampsia [PDF]

American Journal of Reproductive Immunology, 2019
ProblemThe lectin pathway of the complement system may be involved in the pathogenesis of pre‐eclampsia. We aimed to investigate changes in serum concentrations of a broad range of lectin pathway proteins during normal pregnancy and their association with pre‐eclampsia, placental infarctions and intrauterine growth restriction (IUGR).Method of studyWe ...

Backbone dynamics of complement control protein (CCP) modules reveals mobility in binding surfaces [PDF]

, 2004
The regulators of complement activation (RCA) are critical to health and disease because their role is to ensure that a complement-mediated immune response to infection is proportionate and targeted.

Structure-Guided Engineering of a Complement Component C3-Binding Nanobody Improves Specificity and Adds Cofactor Activity

Frontiers in Immunology, 2022
The complement system is a part of the innate immune system, where it labels intruding pathogens as well as dying host cells for clearance. If complement regulation is compromised, the system may contribute to pathogenesis.

Borrelia recurrentis employs a novel multifunctional surface protein with anti-complement, anti-opsonic and invasive potential to escape innate immunity [PDF]

, 2009
Borrelia recurrentis, the etiologic agent of louse-borne relapsing fever in humans, has evolved strategies, including antigenic variation, to evade immune defence, thereby causing severe diseases with high mortality rates.

Quantification of Complement Proteins with Special Reference to C1q: Multiplex Versus ELISA Versus Rocket Immunoelectrophoresis Versus Nephelometry [PDF]

, 2021
Accurate determination of complement component C1q is hampered by the fact that C1q is an immune complex binding protein. Consequently, immunochemical techniques which rely on immune complex formation in fluid phase such as nephelometry and turbidimetry ...

Factor H Family Proteins in Complement Evasion of Microorganisms

Frontiers in Immunology, 2017
Human-pathogenic microbes possess various means to avoid destruction by our immune system. These include interactions with the host complement system that may facilitate pathogen entry into cells and tissues, expression of molecules that defuse the ...

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

Laboratory 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]

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

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

F1000Research, 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 ...

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

, 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 ...
