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

Arthritis &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

Neurobiology 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 ...

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

BMEMat, 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.

Microbial metabolite indole‐3‐propionic acid preserves astrocytic mitochondrial mitofusin 2 to limit neuroinflammation after traumatic brain injury

Interdisciplinary Medicine, EarlyView.
Following traumatic brain injury, indole‐3‐propionic acid (IPA) directly targets the aryl hydrocarbon receptor on astrocytes in the peri‐lesional cortex; this suppresses interferon regulatory factor 1‐driven transcription of the E3 ubiquitin ligase RFFL (ring finger and FYVE‐like domain containing E3 ubiquitin protein ligase).

Anti-SARS-Cov-2 S-RBD IgG Formed after BNT162b2 Vaccination Can Bind C1q and Activate Complement

Journal of Immunology Research, 2022
Background. The ability of vaccine-induced antibodies to bind C1q could affect pathogen neutralization. In this study, we investigated C1q binding and subsequent complement activation by anti-spike (S) protein receptor-binding domain (RBD) specific ...
