Abstract

The identification of lymphocyte subsets with non-overlapping effector functions has been pivotal to the development of targeted therapies in immune-mediated inflammatory diseases (IMIDs)1,2. However, it remains unclear whether fibroblast subclasses with non-overlapping functions also exist and are responsible for the wide variety of tissue-driven processes observed in IMIDs, such as inflammation and damage 3-5. Here we identify and describe the biology of distinct subsets of fibroblasts responsible for mediating either inflammation or tissue damage in arthritis. 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. 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. When adoptively transferred into the joint, FAPα+THY1- fibroblasts selectively mediate bone and cartilage damage with little effect on inflammation, whereas transfer of FAPα+ THY1+ fibroblasts resulted in a more severe and persistent inflammatory arthritis, with minimal effect on bone and cartilage. Our findings describing anatomically discrete, functionally distinct fibroblast subsets with non-overlapping functions have important implications for cell-based therapies aimed at modulating inflammation and tissue damage.

  • Single-cell sequencing indicates common traits are preserved across tissues and species.

    “While single-cell sequencing indicates common traits are preserved49–51, it will become increasingly pressing to define common and specific effects of CAFs.”

    From A framework for advancing our understanding of cancer-associated fibroblasts (2020) · cites this paper as [50]

    The paper’s discussion of homologous fibroblast subsets (indexed under Abstract; page unavailable) reports shared gene-expression profiles in human and mouse arthritic synovium, supporting preservation across species. It does not establish that those traits are preserved across different tissues; both datasets concern synovium. (LLM, conf=0.88)

  • Overwhelming evidence points to a degree of specialization among CAFs, which may reflect the increasingly appreciated specialization of normal fibroblasts.

    “Overwhelming evidence now points to a degree of specialization among CAFs, which may reflect the increasingly appreciated specialization of normal fibroblasts19,50.”
  • A range of mesenchymal progenitor cells are implicated in the initiation and propagation of fibrosis.

    “Recent studies have implicated a range of mesenchymal progenitor cells (MPs) in the initiation and propagation of fibrosis28–30.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
