Complement Factor H-Related Protein 4A Is the Dominant Circulating Splice Variant of CFHR4

Frontiers in Immunology, 2018
Recent research has elucidated circulating levels of almost all factor H-related (FHR) proteins. Some of these proteins are hypothesized to act as antagonists of the important complement regulator factor H (FH), fine-tuning complement regulation on human

Sweeteners for factor H [PDF]

Blood, 2016
In this issue of Blood , [Hyvarinen et al][1][1][2] show that mutant forms of complement factor H, which are commonly associated with atypical hemolytic uremic syndrome (aHUS), have impairments in binding to sialic acid on C3b-coated erythrocytes, platelets, and endothelial cells.

Murine Factor H Co-Produced in Yeast With Protein Disulfide Isomerase Ameliorated C3 Dysregulation in Factor H-Deficient Mice

Frontiers in Immunology, 2021
Recombinant human factor H (hFH) has potential for treating diseases linked to aberrant complement regulation including C3 glomerulopathy (C3G) and dry age-related macular degeneration.

H-Factors in Dense Graphs

Journal of Combinatorial Theory, Series B, 1996
The following asymptotic result is proved. For every \(\varepsilon> 0\), and for every positive integer \(h\), there exists an \(n_0= n_0(\varepsilon, h)\) such that for every graph \(H\) with \(h\) vertices and for every \(n> n_0\), any graph \(G\) with \(hn\) vertices and with minimum degree \[ d\geq \Biggl({\chi(H)- 1\over \chi(H)}+ \varepsilon ...

Contribution of functional and quantitative genetic variants of Complement Factor H and Factor H-Related (FHR) proteins on renal pathology

Nefrología (English Edition), 2022
The complement system is a first line of defence against infectious, tumoral or autoimmune processes, and it is constitutively regulated to avoid excessive or unspecific activation. Factor H (FH), a most relevant complement regulator, controls complement

Two human antibodies to a meningococcal serogroup B vaccine antigen enhance binding of complement Factor H by stabilizing the Factor H binding site.

PLoS Pathogens, 2021
Microbial pathogens bind host complement regulatory proteins to evade the immune system. The bacterial pathogen Neisseria meningitidis, or meningococcus, binds several complement regulators, including human Factor H (FH).

Dengue virus infection induces complement factor H but protein remains cell-associated, with changes intracellularly and in cell surface binding

Exploration of Immunology
Aim: Severe dengue is correlated with a decrease in the circulating complement regulator, factor H (FH) and prior work has shown that dengue virus (DENV) infection induces FH mRNA but not FH protein release.

Levels of soluble complement regulators predict severity of COVID-19 symptoms

Frontiers in Immunology, 2022
The SARS-CoV-2 virus continues to cause significant morbidity and mortality worldwide from COVID-19. One of the major challenges of patient management is the broad range of symptoms observed.

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 ...

Amnion epithelial cells are an effective source of factor H and prevent kidney complement deposition in factor H-deficient mice

Stem Cell Research & Therapy, 2021
Complement factor H (FH) is the main plasma regulator of the alternative pathway of complement. Genetic and acquired abnormalities in FH cause uncontrolled complement activation amplifying, with the consequent accumulation of complement components on the
