摘要：

Immune-regulatory mechanisms of drug-free remission in rheumatoid arthritis (RA) are unknown. We hypothesized that synovial tissue macrophages (STM), which persist in remission, contribute to joint homeostasis. We used single-cell transcriptomics to profile 32,000 STMs and identified phenotypic changes in patients with early/active RA, treatment-refractory/active RA and RA in sustained remission. Each clinical state was characterized by different frequencies of nine discrete phenotypic clusters within four distinct STM subpopulations with diverse homeostatic, regulatory and inflammatory functions. This cellular atlas, combined with deep-phenotypic, spatial and functional analyses of synovial biopsy fluorescent activated cell sorted STMs, revealed two STM subpopulations (MerTK(pos)TREM2(high)and MerTK(pos)LYVE1(pos)) with unique remission transcriptomic signatures enriched in negative regulators of inflammation. These STMs were potent producers of inflammation-resolving lipid mediators and induced the repair response of synovial fibroblasts in vitro. A low proportion of MerTK(pos)STMs in remission was associated with increased risk of disease flare after treatment cessation. Therapeutic modulation of MerTK(pos)STM subpopulations could therefore be a potential treatment strategy for RA. Multiple subpopulations of synovial tissue macrophages with varied transcriptional, phenotypic and functional features may contribute to disease flare and tissue repair in patients with active rheumatoid arthritis and patients in clinical remission.
