This review describes cytokines and the cytokine network in chronic inflammatory diseases such as rheumatoid arthritis (RA). It also discusses how therapies that target cytokines may be feasible and efficacious treatments option for RA. Various targets are considered including blockade of tumour necrosis factor (TNF) and interleukin-1 (IL-1), as well as the targeting of cytokines that play a central role in immune regulation and tissue matrix destruction such as IL-6, IL-15, interferon-gamma (IF...

Cytokines in the pathogenesis of rheumatoid arthritis

Nature Reviews Immunology 2007; 7:429-42

The imbalance between the activity of pro- and anti-inflammatory cytokines favouring induction of autoimmunity, chronic inflammation and joint damage is well known, but how cytokines are organised within a hierarchical regulatory network and which cytokines are the best targets for clinical intervention is uncertain. This review therefore examines the effector function of cytokines in the immunological processes central to the pathogenesis of rheumatoid arthritis (RA). The paper aims to try and ...
