Single-cell RNA sequencing of human peripheral blood mononuclear cells reveals distinct immune response in gout flare and remission

ABSTRACT: Gout typically presents as an acute, self-limiting inflammatory monoarthritis. Based on single-cell RNA sequencing (scRNA-seq), we profiled peripheral blood mononuclear cells (PBMCs) from the same patients with gout flare and gout remission We identified the dynamics of cell abundance, gene expression patterns and biological processes underlying the immune dysregulation of each cell compartment. The single-cell landscape of both innate and adaptive immune responses provides new insights into pathogenesis and therapy of gout flare.

Single-Cell RNA sequencing reveals blood immune features of gout remission patients with monosodium urate crystal deposition.

Project description:As a prominent feature of gout, monosodium urate (MSU) crystal deposition can induce gout flare, yet its impact on blood immune in gout remission patients still remains unclear. In this study, single-cell RNA sequencing (scRNA-seq) is used to compare the gene expression profiling of peripheral blood mononuclear cells (PBMCs) among intercritical gout remission patients, advanced gout remission patients and healthy volunteers. The increase of HLA-DQA1high classical monocytes, and their important role in immune inflammatory responses and osteoclast differentiation are discovered in advanced gout remission patients. Moreover, the differentiation level of CD8+T cells are found to elevate in advanced gout remission patients, which is further validated via flow cytometry. It is also observed that pathways related to bone metabolism and inflammatory responses are overactive in advanced gout remission patients. By analysis on intercellular communication network, immune-related cell-cell interactions among PBMCs are shown to enhance in both intercritical and advanced gout remission patients. The analyses on gene expression and LC-MS/MS together indicate the increased metabolic level of arachidonic acid in gout remission patients with MSU deposition at the intercritical and advanced stage. The study reveals distinctive blood immune characteristics in gout remission with MSU deposition, which provides more sights into its pathogenesis.

Single-cell insights into immune dysregulation in rheumatoid arthritis flare versus drug-free remission

Project description:Immune-mediated inflammatory diseases (IMIDs) are typically characterised by relapsing and remitting flares of inflammation. However, the unpredictability of disease flares impedes their study. Addressing this critical knowledge gap, we used the experimental medicine approach of immunomodulatory drug withdrawal in rheumatoid arthritis (RA) remission to synchronise flare processes, allowing characterisation with unprecedented detail. We used single cell RNA sequencing to analyse the diversity and comparative longitudinal changes in paired circulating lymphocyte samples from 12 patients with RA in remission prior to drug cessation (on-drug remission) and after drug cessation (either off drug flare, or drug-free remission) as part of the Biomarkers of Remission in Rheumatoid Arthritis (BioRRA) Study.

Evaluation of transcriptomic profiles of peripheral blood myeloid cell subsets of RA patients in remission prior to cDMARD withdrawal, and at the point of flare / 6 months after in sustained remission

Project description:To test the contribution of distinct ST-DC populations to either autoimmunity and inflammation or sustained disease remission, we evaluated the phenotypes of their blood precursors in a human model of disease flare following treatment withdrawal in RA patients in disease remission (the BioRRA study, (Baker et al., 2019)). We investigated the frequency and phenotype of PB DC2 and PB-DC3 of RA patients (n=12) in sustained clinical and ultrasound remission achieved with cDMARDs (Baker et al., 2019) by carrying out, and analysing single cell sequencing data at baseline remission levels, and upon endpoint after treatment withdrawal. We identified that PB DCs differ transcriptionally, but not proportionally, at the baseline of patients who sustain remission, versus those who go on to flare, and at endpoint. We propose that the transcriptomic profile of these peripheral blood DCs could be used as a biomarker of flare in remission RA patients.

Expression profile and potential function of circRNAs in peripheral blood mononuclear cells from patients with primary gout

Project description:To determine the expression profile and clinical significance of circular RNAs (circRNAs) in peripheral blood mononuclear cells (PBMCs) of patients with primary gout and healthy control subjects. Human circRNA microarrays were used to identify the differentially expressed circRNAs in primary gout (Gout, n = 5) and healthy subjects (HC, n = 3). Bioinformatics analyses were performed to predict the roles of differently expressed circRNAs. Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to validate the results in 90 gout patients, and 60 healthy control subjects (HC). Microarray analysis indicated that 238 circRNAs were up-regulated and 41 circRNAs were down-regulated in the Gout group (Fold change>1.5, p-value<0.05). Bioinformatics analysis showed that differentially expressed circRNAs were involved in the pathogenesis of gout through a variety of different pathways. Significant association was observed between these circRNAs and lipid metabolism indicators. Our results provide novel insight into the mechanisms of primary gout, and reveal that hsa_circRNA_103657 could effectively discriminate the gout group and the healthy control groups.

Systematic analysis of inflammation and pain pathways in a mouse model of gout

Project description:Gout is a prevalent and painful inflammatory arthritis, and its global burden continues to rise. Intense pain induced by gout attacks is a major complication of gout. Treatment and long-term management for gout patients remain challenging. Despite the discovery of many key immune response and inflammatory genes and pathways in gout, the molecular mechanisms of gout inflammation are still not entirely elucidated. Particularly, systematic studies of gout inflammation and pain are lacking. Using a monosodium urate (MSU) crystals-induced gout model, we performed genome-wide transcriptome analysis for the ankle joint, dorsal root ganglion (DRG), and spinal cord of gout mice. Our results revealed transcriptional changes in both the joint and the nervous system. Furthermore, through integrated analysis with public datasets of mouse inflammatory pain and neuropathic pain models, human GWAS, osteoarthritis (OA), and rheumatoid arthritis (RA), we identified common and unique features associated with acute gout inflammation and severe pain.
