The role of Th1, Th17, and Treg cells in the pathogenesis of rheumatoid arthritis including anti-inflammatory action of Th1 cytokines

Journal Title: Advances in Hygiene and Experimental Medicine - Year 2011, Vol 65, Issue 0

Abstract

Dysregulation in the immune system plays an important role in the pathogenesis of rheumatoid arthritis (RA). The persistent nature of arthritis strengthens the suggestion of immune dysfunction, consisting in predominance of the pro-inflammatory response. It seems that both local and systemic immune abnormalities, including PBMC secreting abnormal levels of pro- and anti-inflammatory cytokines, may be involved in the evolution of the disease. Helper T cells (Th) differentiate towards Th1, Th2, Th17, and Treg cells according to the cytokine microenvironment. Active RA results from the imbalance in distribution of functional pro-inflammatory Th17 and anti-inflammatory Treg cells. Affected Th1 cytokine secretion observed in the course of RA contributes to the increase in IL-17 production and Th17 infiltration in the synovial tissue. Current studies have demonstrated that pro-inflammatory Th1 cytokines may also exert an anti-inflammatory action on the balance between Th17 and Treg cells by promotion of Treg differentiation. In the paper, we also show the influence of TNF-alpha and its inhibitors on the distribution of Th subpopulations in RA patients.
