Complement factor H protects tumor cell-derived exosomes from complement-dependent lysis and phagocytosis.

PLoS ONE, 2021
Exosomes are a class of extracellular vesicles (EVs) that are mediators of normal intercellular communication, but exosomes are also used by tumor cells to promote oncogenesis and metastasis.

Alternative Pathway Dysregulation and the Conundrum of Complement Activation by IgG4 Immune Complexes in Membranous Nephropathy [PDF]

, 2016
Membranous nephropathy (MN), a major cause of nephrotic syndrome, is a non-inflammatory immune kidney disease mediated by IgG antibodies that form glomerular subepithelial immune complexes.

Factor H preserves alternative complement function during ARDS, linked to improved survival

ERJ Open Research, 2023
Background Effective regulation of complement activation may be crucial to preserving complement function during acute respiratory distress syndrome (ARDS). Factor H is the primary negative regulator of the alternative pathway of complement.

Factor H-related protein 4 activates complement by serving as a platform for the assembly of alternative pathway C3 convertase via its interaction with C3b protein [PDF]

, 2012
Human complement factor H-related protein (CFHR) 4 belongs to the factor H family of plasma glycoproteins that are composed of short consensus repeat (SCR) domains.

Factor H complements AMD [PDF]

Science-Business eXchange, 2011
EU and U.S. researchers have revealed what could be the mechanistic underpinnings of the increased risk for age-related macular degeneration in individuals with a common polymorphism in the gene for complement factor H.

Myeloperoxidase influences the complement regulatory activity of complement factor H [PDF]

Rheumatology, 2018
The interaction between neutrophils and activation of alternative complement pathway plays a critical role in the pathogenesis of ANCA-associated vasculitis (AAV). MPO, which can be released from ANCA-stimulated neutrophils, was recently demonstrated to be capable of activating the alternative complement pathway.

Thrombomodulin enhances complement regulation through strong affinity interactions with factor H and C3b-Factor H complex [PDF]

, 2016
Introduction Coagulation and complement systems are simultaneously activated at sites of tissue injury, leading to thrombin generation and opsonisation with C3b.

Genetic variation in CFH predicts phenytoin-induced maculopapular exanthema in European-descent patients [PDF]

, 2017
Objective To characterize, among European and Han Chinese populations, the genetic predictors of maculopapular exanthema (MPE), a cutaneous adverse drug reaction common to antiepileptic drugs.

Mycoplasma hyopneumoniae evades complement activation by binding to factor H via elongation factor thermo unstable (EF-Tu)

Virulence, 2020
Mycoplasmas persist in the host for a long time, suggesting that they possess mechanisms for immune evasion. Factor H is a negative regulator of the complement system, which binds to host cells to avoid unexpected complement activation. In this study, we

Complement factor H related proteins (CFHRs)

Molecular Immunology, 2013
Factor H related proteins comprise a group of five plasma proteins: CFHR1, CFHR2, CFHR3, CFHR4 and CFHR5, and each member of this group binds to the central complement component C3b. Mutations, genetic deletions, duplications or rearrangements in the individual CFHR genes are associated with a number of diseases including atypical hemolytic uremic ...
