    Rheumatoid arthritis (RA) is characterized by chronic synovitis and significant inter-patient variability in disease progression and treatment response.

  • 2

    Immunological heterogeneity in RA arises from genetic susceptibility, epigenetic regulation, autoantibody diversification, and immune-metabolic interactions.

  • 3

    Current biomarkers and imaging techniques may refine patient stratification, but a simple one-marker-one-drug model is not supported by existing evidence.

  • 4

    Biopsy-driven clinical trials like R4RA and STRAP demonstrate both the potential and limitations of synovial pathotype-guided therapy in RA.

  • 5

    Emerging therapeutic strategies, including pharmacomicrobiomics and cell-based therapies, require further validation to address RA treatment challenges.
