Dysregulated Levels of Circulating Autoantibodies against Neuronal and Nervous System Autoantigens in COVID-19 Patients

open access: yesDiagnostics, 2023
Background: COVID-19 is a heterogenous disease resulting in long-term sequela in predisposed individuals. It is not uncommon that recovering patients endure non-respiratory ill-defined manifestations, including anosmia, and neurological and cognitive ...

Anti‐Carbamylated Protein Antibodies Stabilize Carbamylated Histone H3 to Promote Synovial Activation and Neutrophil Extracellular Trap‐Mediated Bone Loss in Rheumatoid Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Carbamylation, a nonenzymatic post‐translational modification, contributes to rheumatoid arthritis (RA) pathogenesis. Anti‐carbamylated protein antibodies (anti‐CarP) occur in around 50% of patients with RA and associate with greater joint damage. Neutrophil extracellular traps (NETs) are a major source of carbamylated autoantigens. We sought

Immune Complexes Shape the Pathogenicity of Autoantibodies in Systemic Autoimmune Diseases: Insights From an FcγRIIIA‐Reporter Assay

open access: yesArthritis &Rheumatology, EarlyView.
Objective Immune complexes (ICs), formed by autoantigen and autoantibody, play a pathogenic role in systemic autoimmune diseases through stimulation of Fcγ receptors (FcγR). However, studies investigating bioactivity of circulating ICs across various diseases remain limited.

Identification of novel, clinically correlated autoantigens in the monogenic autoimmune syndrome APS1 by proteome-wide PhIP-Seq

open access: yeseLife, 2020
The identification of autoantigens remains a critical challenge for understanding and treating autoimmune diseases. Autoimmune polyendocrine syndrome type 1 (APS1), a rare monogenic form of autoimmunity, presents as widespread autoimmunity with T and B ...

Neoepitopes in Type 1 Diabetes: Etiological Insights, Biomarkers and Therapeutic Targets

open access: yesFrontiers in Immunology, 2021
The mechanisms underlying type 1 diabetes (T1D) pathogenesis remain largely unknown. While autoantibodies to pancreatic beta-cell antigens are often the first biological response and thereby a useful biomarker for identifying individuals in early stages ...

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

open access: yesArthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

Ribonucleoprotein complexes as autoantigens [PDF]

open access: yesCurrent Opinion in Immunology, 1995
Many intracellular proteins and nucleic acids, that are involved in important biosynthetic pathways, are targeted by autoantibodies occurring spontaneously in the sera of patients with systemic autoimmune diseases. Frequently, the autoantigens are assembled into multicomponent complexes containing both nucleic acid(s) and proteins.

Autoreactivity Versus Autoimmunity: Characteristics of Autoantigen‐Specific CD4 T Cells in Rheumatoid Arthritis and Health

open access: yesArthritis &Rheumatology, EarlyView.
Objective CD4 T cells specific for citrullinated (cit) peptides are key players in rheumatoid arthritis (RA) immunopathogenesis. Characterizing these cells and identifying features of healthy and RA‐associated autoreactivity will provide valuable insight into disease mechanisms and form the basis of immune state biomarkers to facilitate the next ...

Homocitrullinated Peptides Drive Pro‐Inflammatory T Cell Responses in a Humanized Mouse Model of Rheumatoid Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Anti‐homocitrullinated protein/peptide antibodies are specific to rheumatoid arthritis (RA) and predictive of worse prognosis, suggesting a pathogenic role for autoreactivity to homocitrullinated peptides (HomoCitP). However, T cell responses to HomoCitP remain largely unexplored.
