Interleukin-23 is a key cytokine involved in the generation of Th17 effector cells. Clinical efficacy of an anti-p40 mAb blocking both IL-12 and IL-23 and disease association with single nucleotide polymorphisms in the IL23R gene raise the question of a functional role of IL-23 in psoriasis. In this study, we provide a comprehensive analysis of IL-23 and its receptor in psoriasis and demonstrat...

The aim of this study was to determine the effect of IL-23 on the activity and proliferation of osteoclasts (OC) in co-culture with osteoblasts (OB). OB and OC were individually separated from the skull and femoral bone of a SD rat. OB-OC co-culture with IL-23 added was designed as the experimental group, while the OB-OC co-culture without IL-23 was the control group. In the experimental group,...

Objectives Recent studies have shown that interleukin-23 receptor (IL23R) polymorphisms confer susceptibility to ankylosing spondylitis, psoriasis, psoriatic arthritis and Crohn’s disease. The A allele of rs1004819 was found in a significantly higher frequency among patients suffering from these diseases compared to controls. We aimed to determine the affect of rs1004819 in M694V homozygote FMF...

Graves' orbitopathy (GO) is an autoimmune disease that involves complex immune systems. The mainstays of clinical management for this are surgery, targeted drugs therapy, and no-targeted drug therapy. can improve therapeutic efficacy enhance the quality life GO patients. However, as a second-line treatment GO, such tocilizumab rituximab have very limited effects may be accompanied by side effec...

The nature of inflammatory signals determines the outcome of T cell responses. However, little is known about how inflammatory cytokines provided to human CD8 T cells during activation affects their susceptibility to post-activation cell death. We have examined and compared the effects of the inflammatory cytokine IL-12, as well as the combination of IL-1, IL-6, and IL-23 (IL-1/6/23) on the sus...

Multiple sclerosis is among the most serious inflammatory demyelinating diseases (IDD). Interleukin-23A (IL23A) regulates and coordinates the activities of immune cells by interacting with its receptor IL23R and plays key roles in the pathogenesis of immune inflammatory diseases. IDD, deemed to be a kind of autoimmune diseases, may involve IL23A in the pathogenesis. The aim of this work was to ...

67 www.ijntr.org Abstract—Genome-wide association studies of psoriasis identified interleukin (IL)-12B and IL-23R as significantly associated loci with psoriasis, thus emphasizing to the important role of these genes in the pathogenesis of this disease and have influenced the development of medications that specifically target these key immunological players. Here we report an association study...

Recent studies have demonstrated that T-helper 17 lymphocytes (Th17), which produce mostly IL-17, play a major role in several autoimmune diseases commonly thought to be Th1-related, including Hashimoto's thyroiditis (HT). IL-23, a member of the IL-12 cytokine family, is known to guide T cells toward the Th17 phenotype and its serum levels are increased in several autoimmune disease. Few data a...
