The classical pathway triggers pathogenic complement activation in membranous nephropathy

Nature Communications, 2023
It is generally thought that complement activation in human membranous nephropathy (MN) occurs predominantly via the lectin or alternative pathway. Here, the authors show that the classical pathway is the dominant form of complement activation in MN and ...

Serum complement system activation in normal healing and atrophic non-union of human long bone fractures [PDF]

Frontiers in Immunology
IntroductionThe complement system has an important role in physiological bone healing, as studied mainly in animal models and local bone tissues. However, the role of the complement system in human fractures, particularly at the systemic level, remains ...

The phylogeny of the complement system and the origins of the classical pathway

Immunobiology, 2007
The origins of the complement system have now been traced to near to the beginnings of multi-cellular animal life. Most of the evidence points to the earliest activation mechanism having been more similar to the lectin pathway than to the alternative pathway.

Classical pathway complement activation on human endothelial cells [PDF]

Molecular Immunology, 2007
Endothelial cells regulate vascular integrity and express complement binding proteins including gC1qR/p33 (gC1qR), which recognize C1q, a subunit of the first component of the classical complement pathway. Experiments were performed to investigate classical complement pathway activation on resting endothelial cells and endothelial cells exposed to ...

The Classical Complement Pathway Mediates Microglia-Dependent Remodeling of Spinal Motor Circuits during Development and in SMA

Cell Reports, 2019
Summary: Movement is an essential behavior requiring the assembly and refinement of spinal motor circuits. However, the mechanisms responsible for circuit refinement and synapse maintenance are poorly understood.

Borrelia burgdorferi BBK32 Inhibits the Classical Pathway by Blocking Activation of the C1 Complement Complex. [PDF]

PLoS Pathogens, 2016
Pathogens that traffic in blood, lymphatics, or interstitial fluids must adopt strategies to evade innate immune defenses, notably the complement system.

Gain-of-Function Mutations R249C and S250C in Complement C2 Protein Increase C3 Deposition in the Presence of C-Reactive Protein

Frontiers in Immunology, 2021
The impairment of the alternative complement pathway contributes to rare kidney diseases such as atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathy (C3G).

Functional and Structural Characterization of a Potent C1q Inhibitor Targeting the Classical Pathway of the Complement System

Frontiers in Immunology, 2020
The classical pathway of complement is important for protection against pathogens and in maintaining tissue homeostasis, but excessive or aberrant activation is directly linked to numerous pathologies.
