T-helper cells producing interleukin (IL)-17A and IL-17F cytokines (Th17 cells)
are considered the source of autoimmunity in rheumatoid arthritis (RA). In this
study, we characterized specific pathogenic features of Th17 cells in RA. By
using nano-string technology, we analyzed transcription of 419 genes in the
peripheral blood CCR6(+)CXCR3(-) CD4(+) cells of 14 RA patients and 6 healthy
controls and identified 109 genes discriminating Th17 cells of RA patients from
the controls. Th17 cells of RA patients had an aggressive pathogenic profile and
in addition to signature cytokines IL-17, IL-23 and IL-21, and transcriptional
regulators RAR-related orphan receptor gamma of T cells (ROR?t) and Janus kinase
2 (JAK2), they produced high levels of IL-23R, C-C chemokine ligand type 20
(CCL20), granulocyte-monocyte colony-stimulating factor (GM-CSF ) and
transcription factor Tbet required for synovial homing. We showed that Th17 cells
are enriched with Helios-producing Foxp3- and IL2RA-deficient cells, indicating
altered regulatory profile. The follicular T-helper (Tfh) cells presented a
functional profile of adaptor molecules, transcriptional regulator Bcl-6 and
B-cell activating cytokines IL-21, IL-31 and leukemia inhibitory factor (LIF ).
We observed that anti-tumor necrosis factor (TNF) treatment had a limited effect
on the transcription signature of Th17 cells. Patients in remission retained the
machinery of receptors (IL-23R and IL-1R1), proinflammatory cytokines (IL-17F,
IL-23, IL-21 and TNF ) and adaptor molecules (C-X-C chemokine receptor 5 [CXCR5]
and cytotoxic T-lymphocyte-associated protein 4 [CTLA-4]), essential for
efficient transdifferentiation and accumulation of Th17 cells. This study
convincingly shows that the peripheral blood CCR6(+)CXCR3(-) CD4(+) cells of RA
patients harbor pathogenic subsets of Th17 and Tfh cells, which may
transdifferentiate from Tregs and contribute to perpetuation of the disease.
