Tofacitinib Repairs GM-CSF-induced RA Mitochondrial Dysfunction

ABSTRACT: Rheumatoid arthritis (RA) is an autoimmune disease in which synovial tissue macrophages (MΦs) are the primary producer of inflammatory factors. RA synovial MΦ expansion is strongly linked to ultrasound-detected hypertrophy and pathology, and their frequency is 25-fold upregulated during a flare. Consequently, infiltrating MΦs sense and respond to the RA synovial tissue's high energy and oxygen demands. Thus, understanding how hypoxic RA MΦs experience changes in metabolic activity and mitochondrial remodeling will unravel novel therapeutic strategies. Intriguingly, we found that granulocyte-macrophage colony-stimulating factor (GM-CSF) stimulates an RA MΦ inflammatory profile associated with mitochondrial oxidative stress. This study utilized RNA-seq to investigate the effect of GM-CSF treatment on global gene expression changes in MΦs derived from the peripheral blood of rheumatoid arthritis patients.

Locally renewing resident synovial macrophages provide a protective barrier for the joint [scRNA-seq]

Project description:Macrophages (MΦs) are considered to contribute to chronic inflammatory diseases such as rheumatoid arthritis 1. However, both the exact origin and role of MΦs during inflammatory joint disease remain unclear. Here, we used multiple fate-mapping approaches in conjunction with 3D-light-sheet fluorescence microscopy and single cell RNA sequencing to perform a comprehensive spatiotemporal analysis of the composition, origin and differentiation of MΦ subsets within the healthy and inflamed joint and subsequently studied their roles during arthritis. This approach revealed dynamic membrane-like structures consisting of a distinct population of CX3CR1+ tissue-resident MΦs that formed an internal immunological barrier at the synovial lining and physically secluded the joint. Barrier-forming MΦs displayed features otherwise typical of epithelial cells, and maintained their numbers through a pool of locally proliferating CX3CR1- mononuclear cells embedded into the synovial tissue. Unlike recruited monocyte-derived MΦs, which actively contributed to joint inflammation, such epithelial-like CX3CR1+ lining MΦs restricted the inflammatory reaction by providing a tight junction-mediated shield for intra-articular structures. Our data thus reveal an unexpected functional diversification among synovial MΦs and have important implications for the general role of MΦs in health and disease

Transcription profiling of human synovial cells isolated from patients with rheumatoid arthritis

Project description:Rheumatoid arthritis (RA), a chronic and systemic disease of unknown etiology, is characterized by hyperplasia of synovial cells, which ultimately lead to the destruction of cartilage and bone. To elucidate the molecular mechanisms that lead to RA, we analyzed synovial cells established from patient with RA by oligonucleotide microarrays. Gene expression profiles reveal a novel pathophysiologic function of RA synovial cells as a generator of oxidative stress, and a self-defense mechanism against self-generated oxidative stress. Experiment Overall Design: We isolated synovial cell culture from patients with rheumatoid arthritis and osteoarthritis. Fibroblast from patient with osteoarthritis was used for the reference.

Expression data from Rheumatoid Arthritis synovial tissue samples

Project description:Rheumatoid arthritis (RA) is a complex and clinically heterogeneous autoimmune disease. Microarray analysis of 83 synovial samples provides insight into the expression-level differences between patients at the site of disease activity. Synovial samples from Rheumatoid Arthritis patients were obtained during joint resection and profiled using microarrays.

Single RNA-Seq of synovial tissue macrophages from Rheumatoid Arthritis patients with active disease and in disease remission.

Project description:Treatment refractory Rheumatoid Arthritis (RA) is a major clinical challenge. Drug-free remission is uncommon but provides proof-of-concept that articular immune-homeostasis can be reinstated. In this project, we used single-cell RNA- to study the role of synovial tissue macrophages in maintaining disease remission. We have sequenced synovial tissue macrophages from individuals with healthy synovium (as evaluated by MRI), patients with undifferentiated arthritis (UPA), RA patients naïve to treatment, RA patients resistant to treatment and RA patients in disease remission

Project description:Rheumatoid arthritis (RA) is a chronic, inflammatory joint disease of unknown etiology and pronounced inter-patient heterogeneity. To characterize RA at the molecular level and to uncover key pathomechanisms, we performed whole-genome gene expression analyses. Synovial tissues from rheumatoid arthritis patients were compared to those from to normal donors. Keywords: repeat sample Rheumatoid in comparison to normal donors were investigated. For both groups samples derived from individual patients and or pools of patients were hybridised.

Transcription profiling of human synovial samples from patients with osteoarthritis, rheumatoid arthritis vs controls treated with various drug regimes to characterise RA at the molecular level and to uncover key pathomechanisms

Project description:Rheumatoid arthritis (RA) is a chronic, inflammatory joint disease of unknown etiology and pronounced inter-patient heterogeneity. To characterize RA at the molecular level and to uncover key pathomechanisms, we performed whole-genome gene expression analyses. Synovial tissues from rheumatoid arthritis patients were compared to those from osteoarthritis patients and to normal donors. Keywords: disease state analysis Two disease conditions (rheumatoid arthritis and osteoarthritis) in comparison to normal donors were investigated. For the two disease groups samples derived from three individual patients and two pools of patients were hybridised.
