Recent studies have demonstrated that IL-21 plays an important and non-redundant role in a number of autoimmune animal models indicating that IL-21 could be a common modulator of the adaptive immune response towards self-tissue constituents in diseases such as systemic lupus erythematosus, models of rheumatoid arthritis, multiple sclerosis and type-1 diabetes.

Whereas, CM3D was characterised by a prevailing expression of anti-inflammatory cytokines such as IL-10 and LIF, along with trophic factors involved in different mechanisms leading to tissue regeneration, such as PDGF-BB, FGF-2, I-309, SCF, and GM-CSF; CM2D presented relatively higher levels of IL-6, MCP-1, and IL-21, with recognised pro-inflammatory roles in joint disease and pleiotropic effects in the progression of rheumatoid arthritis (RA).

However, genetic deficiency of IL-21 associates with inflammatory bowel diseases and blockade of IL-21 in the early phases exacerbates the disease progression in some models of rheumatoid arthritis and systemic lupus erythematosus, thus suggesting a dual role of IL-21 in the control of immune-mediated diseases.

Moreover, we found that poly(I:C) was able to drive the differentiation of naive Th cells into an IL-21 but not into an IL-17A-producing phenotype and did this without affecting the levels of transcription factors T-bet, GATA-3, or retinoic acid receptor-related orphan receptor C. Finally, we found that the IL-21-producing cells that were differentiated in response to poly(I:C) expressed the chemokine receptor CXCR3, which is important in the recruitment of T cells into inflamed joints in rheumatoid arthritis.
