Efficiency of cell-based assays in detecting AChR antibodies in myasthenia gravis sera with low antibody concentrations as determined by radioimmunoprecipitation assay

ObjectivesWe investigated whether the acetylcholine receptor (AChR) cluster cell-based assay (CBA) is effective in detecting AChR antibodies in sera from myasthenia gravis (MG) patients with low antibody concentrations, as determined by radioimmunoprec…

Nonlinearity and sex differences in the performance of a polygenic risk score for juvenile idiopathic arthritis

BackgroundJuvenile idiopathic arthritis (JIA) is an immune-mediated pediatric disease believed to result from a complex interplay of genetic and environmental factors. Genome-wide association studies have enabled calculation of polygenic risk scores (P…

Single-cell analysis reveals significant transcriptomic alterations in preclinical Crohn’s disease

Despite the increasing incidence of Crohn’s disease (CD), its early immune disturbances have not all been described yet. We analysed single-cell RNASeq data from peripheral blood mononuclear cells of patients with incidentally-diagnosed CD, and compare…

Performance of new pp65-IGRA for the quantification of HCMV-specific CD4+ T-cell response in healthy subjects and in solid organ transplant recipients

Immune control of human cytomegalovirus (HCMV) replication is critical in bone marrow and solid organ transplant recipients, where uncontrolled replication can lead to high mortality. Current commercial immune monitoring tools have several limitations,…

C-reactive protein conformations and their association with the IL-1β/IL-6 pathway in ocular inflammatory conditions

IntroductionC-reactive protein (CRP) plays a critical role in the innate immune system and serves as a biomarker for various inflammatory conditions. CRP is a dynamic protein undergoing conformational changes between pentameric (pCRP) and monomeric (mC…

IRAK3 is upregulated in rheumatoid arthritis synovium and delays the onset of experimental arthritis

Tumour necrosis factor (TNF) is a potent inducer of endotoxin tolerance-associated molecules, such as interleukin-1 receptor-associated kinase 3 (IRAK3), and also a therapeutic target in inflammatory autoimmune diseases, as it upregulates the productio…

Long donor leukocyte telomeres raise risk of severe COVID-19 in recipients of allogeneic hematopoietic cell transplant

IntroductionShort leukocyte telomeres are associated with an increased risk of severe COVID-19 in the general population, likely due to a weakened T-cell response to SARS-CoV-2. This may lead to an amplified neutrophil response, causing pulmonary damag…

Myasthenia gravis with double-seropositive acetylcholine receptor and low-density lipoprotein receptor-related protein 4 antibodies combined with muscle atrophy: a case report and literature review

ObjectiveTo investigate the clinical characteristics and mechanisms of muscle atrophy in myasthenia gravis (MG) patients who are double-seropositive with acetylcholine receptor (AChR) antibodies and low-density lipoprotein receptor-related protein 4 (L…
