MafB is a critical regulator of complement component C1q [PDF]

open access: yes, 2017
The transcription factor MafB is expressed by monocytes and macrophages. Efferocytosis (apoptotic cell uptake) by macrophages is important for inhibiting the development of autoimmune diseases, and is greatly reduced in Mafb-deficient macrophages.

Continual Low-Level Activation of the Classical Complement Pathway [PDF]

open access: yesThe Journal of Experimental Medicine, 2001
There is evidence that the classical complement pathway may be activated via a “C1-tickover” mechanism, analogous to the C3-tickover of the alternative pathway. We have quantitated and characterized this pathway of complement activation. Analysis of freshly collected mouse and human plasma revealed that spontaneous C3 activation rapidly occurred with ...

The Functional Amyloid Curli Protects Escherichia coli against Complement-Mediated Bactericidal Activity

open access: yesBiomolecules, 2018
Escherichia coli strains may be beneficial or pathogenic. Many E. coli strains that cause human disease, especially those responsible for bacteremia and sepsis, express virulence factors that impart resistance to the complement system.

Different Complement Activation Pathways Underly Cognitive Impairment and Type 2 Diabetes Mellitus Combined With Cognitive Impairment

open access: yesFrontiers in Aging Neuroscience, 2022
BackgroundThe immune response and the complement system are associated with cognitive impairment and diabetes mellitus, respectively. Activation of the complement system in these diseases occurs mainly through either the classical pathway or the ...

Peptide Inhibitor of Complement C1 (PIC1) Rapidly Inhibits Complement Activation after Intravascular Injection in Rats. [PDF]

open access: yesPLoS ONE, 2015
The complement system has been increasingly recognized to play a pivotal role in a variety of inflammatory and autoimmune diseases. Consequently, therapeutic modulators of the classical, lectin and alternative pathways of the complement system are ...

Human complement factor H. Two factor H proteins are derived from alternatively spliced transcripts [PDF]

open access: yes, 1991
The human complement factor H is an important component in the control of the alternative pathway of complement activation. We have previously shown that at least three factor H homologous mRNA species of 4.3 kb, 1.8 kb and 1.4 kb in length are ...

Ischemia and reperfusion injury in kidney transplantation : relevant mechanisms in injury and repair [PDF]

open access: yes, 2020
Ischemia and reperfusion injury (IRI) is a complex pathophysiological phenomenon, inevitable in kidney transplantation and one of the most important mechanisms for non- or delayed function immediately after transplantation.

Human pentraxin 3 binds to the complement regulator c4b-binding protein. [PDF]

open access: yesPLoS ONE, 2011
The long pentraxin 3 (PTX3) is a soluble recognition molecule with multiple functions including innate immune defense against certain microbes and the clearance of apoptotic cells.

A New Tool for Complement Research: In vitro Reconstituted Human Classical Complement Pathway

open access: yesFrontiers in Immunology, 2018
The complement, as part of the innate immune system, represents the first line of defense against Gram-negative bacteria invading the bloodstream. The complement system is a zymogen cascade that ultimately assemble into the so-called membrane attack ...
