Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Complement C1q formation of immune complexes with milk caseins and wheat glutens in schizophrenia

open access: yesNeurobiology of Disease, 2012
Immune system factors including complement pathway activation are increasingly linked to the etiology and pathophysiology of schizophrenia. Complement protein, C1q, binds to and helps to clear immune complexes composed of immunoglobulins coupled to ...

Menopause leads to elevated expression of macrophage-associated genes in the aging frontal cortex: rat and human studies identify strikingly similar changes. [PDF]

open access: yes, 2012
BACKGROUND The intricate interactions between the immune, endocrine and central nervous systems shape the innate immune response of the brain. We have previously shown that estradiol suppresses expression of immune genes in the frontal cortex of ...

Targeting neutrophil extracellular traps in metabolic and immune niche: Nanomaterials for diabetes tissue regeneration

open access: yesBMEMat, EarlyView.
The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.

Correlation of Serum Anti-Clq Antibody Levels and Disease Activity in Patients with Systemic Lupus Erythematosus

open access: yesIndonesian Journal of Rheumatology, 2019
Background. Antibody to complement C1q (Anti-C1q Antibody) can be found in Systemic Lupus Erythematosus (SLE) patients. Complement C1q plays a role in the clearance of apoptotic cells and immune complexes.

The tumour microenvironment links complement system dysregulation and hypoxic signalling. [PDF]

open access: yes, 2018
The complement system is an innate immune pathway typically thought of as part of the first line of defence against "non-self" species. In the context of cancer, complement has been described to have an active role in facilitating cancer-associated ...

IgG Subclass Profiles of HLA Antibodies Enhance Prediction of C1q-Binding in Kidney Transplant Recipients

open access: yesDiagnostics
Background/Objectives: While standard Luminex single antigen bead (SAB) detects total IgG antibodies, qualitative differences among IgG subclasses may influence their immunologic risk.

Glomerular C1q deposition and serum anti-C1q antibodies in anti-glomerular basement membrane disease [PDF]

open access: yes, 2013
BACKGROUND: Anti-glomerular basement membrane (GBM) disease is a well-known antibody-induced autoimmune disease. A few patients have glomerular C1q deposition, but it is usually absent on renal histopathology.

Increase of C1q biosynthesis in brain microglia and macrophages during lentivirus infection in the rhesus macaque is sensitive to antiretroviral treatment with 6-chloro-2′,3′-dideoxyguanosine

open access: yesNeurobiology of Disease, 2005
Complement activation in the brain contributes to the pathology of neuroinflammatory and neurodegenerative diseases such as neuro-AIDS. Using semiquantitative in situ hybridization and immunohistochemistry, we observed an early and sustained increase in ...
