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

open access: yesPLoS 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.

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

open access: yesERJ 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.

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

open access: yesRheumatology, 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.

Complement and coagulation crosstalk – Factor H in the spotlight

open access: yesImmunobiology, 2023
The immune complement and the coagulation systems are blood-based proteolytic cascades that are activated by pathway-specific triggers, based on protein-protein interactions and enzymatic cleavage reactions. Activation of these systems is finely balanced and controlled through specific regulatory mechanisms.

Complement factor H and the hemolytic uremic syndrome [PDF]

open access: yesThe Journal of Experimental Medicine, 2007
Immune recognition is coupled to powerful proinflammatory effector pathways that must be tightly regulated. The ancient alternative pathway of complement activation is one such proinflammatory pathway. Genetic susceptibility factors have been identified in both regulators and activating components of the alternative pathway that are associated with ...

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

open access: yesVirulence, 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 Family Proteins Modulate Monocyte and Neutrophil Granulocyte Functions

open access: yesFrontiers in Immunology, 2021
Besides being a key effector arm of innate immunity, a plethora of non-canonical functions of complement has recently been emerging. Factor H (FH), the main regulator of the alternative pathway of complement activation, has been reported to bind to ...

The outer membrane protease PgtE of Salmonella enterica interferes with the alternative complement pathway by cleaving factors B and H

open access: yesFrontiers in Microbiology, 2015
The virulence factor PgtE is an outer membrane protease (omptin) of the zoonotic pathogen Salmonella enterica that causes diseases ranging from gastroenteritis to severe enteric fever. It is surface exposed in bacteria that have a short-chain, i.e. rough

Is Complement Factor H Tyr402His Variant a Potential Cause of Ankylosing Spondylitis?

open access: yesHaseki Tıp Bülteni, 2020
Aim:Ankylosing spondylitis (AS) is an autoimmune disease caused by chronic inflammatory response. Complement system is the major component of the innate immune defence. In this study, we investigated the potential association between complement factor H (
