Complement Factor H-Related Proteins FHR1 and FHR5 Interact With Extracellular Matrix Ligands, Reduce Factor H Regulatory Activity and Enhance Complement Activation

Frontiers in Immunology, 2022
Components of the extracellular matrix (ECM), when exposed to body fluids may promote local complement activation and inflammation. Pathologic complement activation at the glomerular basement membrane and at the Bruch’s membrane is implicated in renal ...

Truncated forms of human complement factor H [PDF]

Biochemical Journal, 1989
By the use of Western-blot analyses with polyclonal anti-(Factor H) antibodies, two low-Mr protein species of Mr 41,000 and 37,000 under non-reducing conditions and 43,000 and 40,000 under reducing conditions are consistently detected together with the well-known 155,000-Mr Factor H in human plasma and serum. These two additional species are also found

Contribución de variantes funcionales y cuantitativas del Factor H y las proteínas FHRs (Factor H-Related proteins) del Complemento en patología renal

Nefrología, 2022
Resumen: El sistema del Complemento protege al organismo frente a procesos infecciosos, tumorales y autoinmunes, y requiere una regulación muy estricta para evitar una activación excesiva o inespecífica.

Microbes bind complement inhibitor factor H via a common site. [PDF]

PLoS Pathogens, 2013
To cause infections microbes need to evade host defense systems, one of these being the evolutionarily old and important arm of innate immunity, the alternative pathway of complement. It can attack all kinds of targets and is tightly controlled in plasma

Reference Intervals of Factor H and Factor H-Related Proteins in Healthy Children

Frontiers in Immunology, 2018
Complement is activated as part of the innate immune defense against invading pathogens. Also, it helps to remove apoptotic debris and immune complexes from the circulation.

Complement factors (H) into thrombosis [PDF]

Blood, 2017
In this issue of Blood, Ueda et al demonstrate that a mutation in factor H (FH) disrupts host cell interactions, leading to dysregulation of complement, systemic thrombotic angiopathy, and hemolytic uremic syndrome ...

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 ...
