    CD4 T cells specific for citrullinated peptides are crucial in the immunopathogenesis of rheumatoid arthritis (RA).

  • 2

    The study assessed autoreactive CD4 T cells from healthy controls and RA patients using MHC II-peptide tetramers and spectral flow cytometry.

  • 3

    No significant difference in autoreactive T cell frequency was found between healthy controls and RA patients.

  • 4

    The research focused on the memory CD4 T cell compartment to characterize autoreactive T cells.

  • 5

    Identifying features of autoreactivity in RA may aid in developing immune state biomarkers for future treatments.
