To clarify the significance of immunometabolism in systemic lupus erythematosus (SLE), and to determine effect calcium/calmodulin-dependent protein kinase 4 (CaMK4) on T cell metabolism.Metabolomic profiling was performed using capillary electrophoresis mass spectrometry naive cells from MRL/lpr mice treated with anti-CD3/CD28 antibodies absence or presence a CaMK4 inhibitor (KN-93). The expression GLUT1 CD4+ healthy controls (n = 16), patients inactive SLE 13), active 14) examined by flow...
The precise cytokine networks in the serum of individuals with familial Mediterranean fever (FMF) that are associated its pathogenesis have been unknown. Here, we attempted to identify specific biomarkers diagnose or assess disease activity FMF patients. We measured levels 45 cytokines 75 patients and 40 age-matched controls by multisuspension array. "attack" "remission" was classified Japan College Rheumatology-certified rheumatologists according Tel Hashomer criteria. Cytokines were ranked...
The autoimmune response in rheumatoid arthritis (RA) is marked by the presence of anti-citrullinated protein antibodies (ACPAs). A notable feature IgG ACPA abundant expression N-linked glycans variable domain. However, domain glycosylation (VDG) across disease stages, and its to therapy, are poorly described. To understand dynamics, we investigated abundance VDG 1,498 samples from individuals different clinical stages.Using liquid chromatography, analyzed profiles 7 cohorts Japan, Canada,...
Objective: To determine the association of distinct clinical subsets with myositis‐specific autoantibodies (MSAs) towards anti‐155/140‐kDa polypeptides [anti‐155/140 antibodies (Abs)], anti‐140‐kDa (anti‐140 Abs), and anti‐aminoacyl tRNA synthetases (ARS Abs) in Japanese patients dermatomyositis (DM).Methods: We compared features short‐term prognoses 30 DM whose serological status included these MSAs. The MSAs were determined by immunoprecipitation.Results: Anti‐155/140 Abs (n = 5), anti‐140...
Objective. We evaluated the significance of power Doppler ultrasonography (PDUS) score by comparing it with serum biomarkers and clinical disease activity.
Analysis of circulating immune complexes (CICs) produced during an response may be useful in elucidating some aspects this process. Identification antigens incorporated into CICs provides information that helpful developing diagnostic and treatment strategies for autoimmune diseases, infection, cancer, transplantation therapy, such might more relevant than on free antigens. Because contain many antigens, comprehensive identification profiling is effective immunoblotting detection.We...
