Trajectory analysis and identification of fibroblast subpopulations from human RA patients. The heat map shows the (row-scaled) expression of the top 20 (by p-value) discovered significant, conserved marker genes for each cluster (BH adjusted p-value <0.1 in separate tests of cells from each of the n=3 biological replicate samples, two-sided Wilcoxon tests). The expression of C5orf30 is highest in RA synovial fibroblasts (RASFs) and macrophages, key mediators of inflammation and tissue damage in RA . Single-cell RNA-sequencing reveals distinct fibroblast…. Fig. Single-cell RNA-seq of rheumatoid arthritis synovial tissue using low-cost microfluidic instrumentation. Mouse synovial FAPα expression. We show that deletion of FAPα+ synovial cells suppressed both inflammation and bone erosions in murine models of resolving and persistent arthritis. Its work brings people from across the world to Birmingham, including researchers, teachers and more than 6,500 international students from over 150 countries. Single-cell transcriptional analysis identified two distinct fibroblast subsets within the FAPα+ population: FAPα+THY1+ immune effector fibroblasts located in the synovial sub-lining, and FAPα+THY1- destructive fibroblasts restricted to the synovial lining layer. Change in wrist and ankle joint thickness…. 2001 Oct;60(5):309-18. doi: 10.1007/s003930170030.

We show that deletion of fibroblast activation protein-α (FAPα)+ fibroblasts suppressed both inflammation and bone erosions in mouse models of resolving and persistent arthritis. Although we focused upon T cells and B cells in this review, other cell subsets residing in arthritic synovium, such as dendritic cells, innate lymphoid cells and synovial fibroblasts, also play a distinct role in the course of arthritis and may contribute to bone damage 71, 72, 73.
