Role of complement activation in anti-neutrophil cytoplasmic antibody-associated glomerulonephritis

open access: yesFrontiers in Medicine, 2022
Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is an autoimmune disease characterized by necrotizing inflammation of small or medium vessels, causing ANCA associated glomerulonephritis (AAGN).

Novel Evasion Mechanisms of the Classical Complement Pathway [PDF]

open access: yesThe Journal of Immunology, 2016
Abstract Complement is a network of soluble and cell surface-associated proteins that gives rise to a self-amplifying, yet tightly regulated system with fundamental roles in immune surveillance and clearance. Complement becomes activated on the surface of nonself cells by one of three initiating mechanisms known as the classical, lectin,

Complement in the Initiation and Evolution of Rheumatoid Arthritis

open access: yesFrontiers in Immunology, 2018
The complement system is a major component of the immune system and plays a central role in many protective immune processes, including circulating immune complex processing and clearance, recognition of foreign antigens, modulation of humoral and ...

Is the Complement Protein C1q a Pro- or Anti-tumorigenic Factor? Bioinformatics Analysis Involving Human Carcinomas

open access: yesFrontiers in Immunology, 2019
C1q is the first subcomponent of the classical pathway of the complement system and belongs to the C1q/Tumor Necrosis Factor superfamily. C1q can perform a diverse range of immune and non-immune functions in a complement-dependent as well as -independent

Complement-coagulation cross-talk: a potential mediator of the physiological activation of complement by low pH

open access: yesFrontiers in Immunology, 2015
The complement system is a major constituent of the innate immune system. It not only bridges innate and adaptive arms of the immune system but also links the immune system with the coagulation system.

Is the A-Chain the Engine That Drives the Diversity of C1q Functions? Revisiting Its Unique Structure

open access: yesFrontiers in Immunology, 2018
The immunopathological functions associated with human C1q are still growing in terms of novelty, diversity, and pathologic relevance. It is, therefore, not surprising that C1q is being recognized as an important molecular bridge between innate and ...

Chimeric Proteins Containing MAP-1 and Functional Domains of C4b-Binding Protein Reveal Strong Complement Inhibitory Capacities

open access: yesFrontiers in Immunology, 2018
The complement system is a tightly regulated network of proteins involved in defense against pathogens, inflammatory processes, and coordination of the innate and adaptive immune responses.

Carbamylation of immunoglobulin abrogates activation of the classical complement pathway [PDF]

open access: yesEuropean Journal of Immunology, 2014
Post‐translational modifications of proteins significantly affect their structure and function. The carbamylation of positively charged lysine residues to form neutral homoitrulline occurs primarily under inflammatory conditions through myeloperoxidase‐dependent cyanate (CNO−) formation.
