Overview

Preclinical study demonstrates that zinc finger protein 24 boosts pathogenic Tc17 and Tc17.1 cell function in collagen-induced arthritis, highlighting a potential therapeutic target.

Key Points

To elucidate the regulatory mechanisms driving pro-inflammatory synovial Tc17 and Tc17.1 cells in rheumatoid arthritis pathogenesis.
Conducted transcriptome profiling on sorted live synovial Tc17 and Tc17.1 cells isolated from a mouse model of collagen-induced arthritis (CIA).
Evaluated in vitro ZNF24 knockdown effects on cell differentiation, cytokine profiles, and synovial fibroblast interactions, followed by adoptive transfer assays in CIA mice and validation in human RA samples.
ZNF24 knockdown impaired Tc17 and Tc17.1 differentiation and effector function in vitro, significantly dampening expression of IL-17A, RORγt, GM-CSF, IL-22, perforin, and granzyme B.
Adoptive transfer of Tc17.1 cells exacerbated arthritis severity in CIA mice, whereas ZNF24 knockdown effectively mitigated this disease aggravation.
Direct cell contact with synovial fibroblasts upregulated ZNF24 in Tc17 and Tc17.1 cells, mirroring expression patterns identified in human rheumatoid arthritis patients.
