Romatoid Artrit patofizyolojisi: Sitokin ve Sitokin ilişkili hücre hedefleri ile ilgili güncelleme

Rheumatology doi:10.1093/rheumatology/ket414

Despite biologic therapies greatly improving the treatment of rheumatoid arthritis, many patients do not respond to current treatments or do not maintain response to these treatments. This review covers the evidence for the newly discovered role of Th17 cells, IL-12 and IL-17 family of cytokines in the pathogenesis of RA as well as the development of new therapies targeting these cytokines. With current biologics targeting cytokines such as TNF, IL-1ß and IL-6, the discovery of the Th17 subset o...

STA-21, gelecek vadeden STAT3 inhibitörü olup Th17 ve Treg resiprok olarak düzenler, osteoklastogenezi inhibe eder ve otoimmün inflamasyonu iyileştirir

Arthritis and Rheumatism doi: 10.1002/art.38305

STAT3 (signal transducer and activator of transcription 3) is the major transcription factor in the differentiation of Th17 cells, which along with IL-17 are significant in the development of RA. STA-21 is a new small molecule with significant inhibitory effects on STAT3, impeding DNA binding activity, dimerization and STAT3-dependent luciferase activity. While the effect of STA-21 in RA has not been fully determined, it has been hypothesised that STA-21 will suppress arthritis in animal models ...

Romatoid artritte yeni hücreler ve sitokin hedefleri

Nat Rev Rheumatol. 2013. doi:10.1038/nrrheum.2013.168

Despite major progress in the treatment of RA over the past decade, sustained clinical remission remains elusive. The identification of new treatment targets is therefore necessary, with much research currently being undertaken in this area. Novel therapeutic approaches currently being investigated include T cell-directed therapies targeting both T cell activation and regulation; and the targeting of pathogenic B cell functions, including the use of depleting and non-depleting B cell-directed an...

Cytokine networks—towards new therapies for rheumatoid arthritis

Nature Clinical Practice 2005; 1(1):31-9

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 ...

Modulation of innate and adaptive immune responses by tofacitinib (CP-690,550)

Journal of Immunology 2011; 186(7):4234-43

This study investigated the effects of the novel Janus kinase (JAK) inhibitor CP-690,550 (now known as tofacitinib) on adaptive and innate immune responses, in order to establish the mode of action of JAK inhibitors in the setting of inflammatory diseases. The inhibition of specific JAK/STAT-dependent pathways by CP-690,550 was determined through analysis of cytokine stimulation of mouse and human T cells in vitro.The effects of CP-690,550 on Th-cell differentiation of naive murine CD4+...
