MetabolomicsRA-MAP: mapping the molecular immunological landscape in early rheumatoid arthritis with vaccine controls

Rheumatoid arthritis (RA) is a chronic inflammatory disorder with poorly defined aetiology characterised by synovial inflammation with variable disease severity and drug responsiveness. To investigate the peripheral blood immune cell landscape of RA, we performed comprehensive clinical and molecu...

MetabolomicsAltered fecal metabolomics and potential biomarkers of psoriatic arthritis differing from rheumatoid arthritis
Psoriatic arthritis (PsA) is a chronic inflammatory joint disease, and the diagnosis is quite difficult due to the unavailability of reliable clinical markers. This study aimed to investigate the fecal metabolites in PsA by comparison with rheumatoid arthritis (RA), and to identify potential diagnos...

MetabolomicsStage-specific roles of microbial dysbiosis and metabolic disorders in rheumatoid arthritis

OBJECTIVE: Rheumatoid arthritis (RA) is a progressive disease including four stages, where gut microbiome is associated with pathogenesis. We aimed to investigate stage-specific roles of microbial dysbiosis and metabolic disorders in RA.

METHODS: We investi...

Metabolomics1H NMR Metabolomics Identifies Underlying Inflammatory Pathology in Osteoarthritis and Rheumatoid Arthritis Synovial Joints
Despite osteoarthritis (OA) and rheumatoid arthritis (RA) being typically age-related, their underlying etiologies are markedly different. We used 1H nuclear magnetic resonance (NMR) spectroscopy to identify differences in metabolite profiles in low volumes of OA and RA synovial fluid (SF). SF was a...

MetabolomicsThe gut microbiome and metabolites are altered and interrelated in patients with rheumatoid arthritis

The relationship among the gut microbiome, global fecal metabolites and rheumatoid arthritis (RA) has not been systematically evaluated. In this study, we performed 16S rDNA sequencing and liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based nontargeted metabolomic profiling ...

MetabolomicsSuccinate drives macrophage inflammation by promoting GPR91 mitochondrial signaling in rheumatoid arthritis

Succinate is implicated in rheumatoid arthritis (RA) and other inflammatory diseases via its receptor, G protein-coupled receptor 91 (GPR91). Despite its therapeutic potential, conflicting reports on its inflammatory roles have hindered GPR91-targeted treatm...

MetabolomicsMetabolic profiling of rheumatoid arthritis neutrophils reveals altered energy metabolism that is not affected by JAK inhibition
Neutrophils play a key role in the pathophysiology of rheumatoid arthritis (RA) where release of ROS and proteases directly causes damage to joints and tissues. Neutrophil function is directly affected by Janus Kinase (JAK) inhibitor drugs, including tofacitinib and baricitinib, which are clinically...

MetabolomicsMulti-omics integration reveals Yu-Xue-Bi tablets attenuate rheumatoid arthritis via metabolic reprogramming-mediated Piezo1 suppression

As a systemic chronic inflammatory disease, Rheumatoid arthritis (RA) is characterized by progressive inflammation, bone and cartilage destruction, leading to significant disability, reduced lifespan, and increased mortality. The clinical use of conventional medications including nonsteroidal ant...
