Targeting necroptosis in muscle fibers ameliorates inflammatory myopathies

Nature Communications, 2022
Polymyositis (PM) is a chronic inflammatory myopathy characterized by progressive muscle weakness. Here the authors showed that muscle fibers in PM undergo necroptosis and aggravate inflammation via releasing pro-inflammatory molecules such as HMGB1.

A Case of Multiple Mitochondrial Dysfunctions Syndrome 1 and Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Multiple mitochondrial dysfunctions syndrome 1 (MMDS1, MIM #605711) due to NFU1 gene defects is an ultra‐rare autosomal recessive inborn error of metabolism associated with reduced function of NFU1 iron–sulfur cluster (ISC) scaffold protein.

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Investigating the Role of Type I Interferon Signaling on Muscle Disease Using Mouse Models

Arthritis &Rheumatology, EarlyView.
Objective Dysregulated type I interferon (IFN) signaling contributes to autoimmune myositis pathogenesis. We investigated the therapeutic effects of JAK inhibitors in two mouse models. We also examined how type I IFNs affect muscle vasculature. Methods Myositis was induced in major histocompatibility complex class I double transgenic ([TRE‐H‐2Kb (H ...

Amyloid myopathy mimicked with idiopathic inflammatory myopathy diagnosed using Congo red staining: a case report

BMC Neurology
Amyloid myopathy often occurs in the context of systemic amyloidosis, as a rare manifestation of “light chain” (AL) amyloidosis, accounting for 1% of its incidence.

Improved Detection of Myositis‐Specific Autoantibodies Using Luciferase Immunoprecipitation Systems Assay: Comparison With Line Blot and Conventional Immunoprecipitation

Arthritis &Rheumatology, EarlyView.
Objective Myositis‐specific autoantibodies guide the diagnosis and classification of idiopathic inflammatory myopathies, but current immunoassays vary in accuracy, particularly for autoantibodies associated with interstitial lung disease. To compare the performance of the luciferase immunoprecipitation systems (LIPS) assay with line blot and ...

Interleukin‐2 Deprived State of Regulatory T cells and Their Recovery by Low‐Dose Interleukin‐2 in Patients With Inflammatory Myopathies

Arthritis &Rheumatology, EarlyView.
Objective Regeneration and expansion of Treg by low‐dose interleukin‐2 (IL‐2) therapy is considered a potential treatment strategy for a wide range of autoimmune diseases. To provide a pathophysiologically‐based rationale for low‐dose IL‐2 therapy, we investigated whether reversible defects in the Treg–IL‐2 axis emerge in inflammatory myopathies ...

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

Arthritis &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.

T Cell Plasticity in Systemic Lupus Erythematosus Revealed by Large‐Scale T Cell Receptor Repertoire and Transcriptome Studies

Arthritis &Rheumatology, EarlyView.
Objective We aimed to characterize CD4+ T cell plasticity in human systemic lupus erythematosus (SLE) by leveraging T cell receptor (TCR) repertoire features as markers of prior lineage states, integrating TCR and transcriptomic profiling to delineate plasticity patterns and evaluate their association with clinical disease activity. Methods We used TCR

Polymyositis anti-SRP antibodies and pregnancy about 2 cases

The Pan African Medical Journal, 2016
Anti-SRP myopathy represents 4 to 6% of all the inflammatory myopathies. It has been described since the 80s and its influence on pregnancy and vice versa has been highlighted recently.
