Romatoid artritte tofacitinibin lenfositler üzerindeki etkileri: Etkinlikle ve enfeksiyöz yan etkilerle olan ilişki

Rheumatology doi:10.1093/rheumatology/ket466

Due to its function as a JAK1/3 inhibitor, tofacitinib has effects on a wide ranging variety of cells. The authors of this paper have previously reported a suppression in cytokine production by CD4+ T lymphocytes caused by tofacitinib, while others have reported reduced chemokine production from fibroblast-like synoviocytes. The effects of tofacitinib on other cells however remain largely unknown. This study focused on tofacitinib’s effects on CD4+ T lymphocyte proliferation and on subsets of ly...

JAK inhibitörü Tofasitinib İnsan Monosit Kökenli Dendritik Hücrelerinin T hücre stimülator kapasitesini azaltır

The role of JAKs is highly important in lymphocyte differentiation, but their function in dendritic cells in unknown. In this study, the authors used tofacitinib, a JAK inhibitor, to assess the function of these kinases in dendritic cell activity. The results show that tofacitinib reduced the expression of CD80/CD86 by suppressing the activation of interferon regulatory factor (IRF)-7 and production of type 1 interferon (IFN), and also decreased T cell stimulatory capability. This suggests a nov...

Janus kinases inhibitors in autoimmune diseases

Annals of the Rheumatic Diseases 2013; 72:ii111-ii115

This review describes the role of various cytokines in rheumatoid arthritis (RA) and related diseases. This includes an overview of the different types of cytokine receptors including type I, which bind some of the interleukins (ILs), colony stimulating factors (CSFs) and hormones such as erythropoietin, prolactin and growth hormone (GH); and type II, which bind to interferons and IL-10-related proteins. In addition, the cytoplasmic domain of type I and II cytokine receptors bind to members of a...
