INTRODUCTION A hallmark of systemic autoimmune diseases like systemic lupus erythematosus (SLE) is the increased expression of interferon (IFN) type I inducible genes, so-called IFN type I signature. Recently, T-helper 17 subset (Th17 cells), which produces IL-17A, IL-17F, IL-21, and IL-22, has been implicated in SLE. As CCR6 enriches for Th17 cells, we used this approach to investigate whether...

Psoriasis is the most common chronic inflammatory skin disease in adults, characterized by immune cell infiltration, expansion of disease-associated lymphocytes, and epidermal hyperplasia. Increasing evidence highlights central role interleukin (IL)-17A IL-17F its pathobiology. IL-17A IL-17F, known to be produced activated T helper 17 cells, can form homodimers or heterodimers drive aberrant ke...

IL-23 induces IL-17 production in activated CD4+ T cells and participates in host defense against many encapsulated bacteria. However, whether the IL-23/IL-17 axis contributes to a Mycoplasma pneumoniae (Mp)-induced lung inflammation (e.g., neutrophils) has not been addressed. Using an acute respiratory Mp infection murine model, we found significantly up-regulated lung IL-23p19 mRNA in the ear...

PURPOSE To investigate the association of IL-17F rs763780T>C with cancer risk. MATERIALS AND METHODS We searched the Cochrane Central Library, PubMed, MEDLINE, EMBASE, CNKI (China National Knowledge Infrastructure) and WangFang databases until May 2014 for a meta-analysis conducted using RevMan 5.2 software. RESULTS A total of ten papers were included into this meta analysis, involving 3, 3...

Previous studies have suggested a critical role for interleukin IL-17F in innate and adaptive immunity in vivo and its abnormal expression was found to play a bridging role in several neurological disorders. In this study, we investigated the association between functional polymorphisms in IL-17F and Tourette’s syndrome (TS) in a Chinese Han population. We recruited 407 TS nuclear family trios ...

Interleukin-17A (IL-17A) is the signature cytokine of the recently identified T helper 17 (Th17) cell subset. IL-17 has six family members (IL-17A to IL-17F). Although IL-17A and IL-17F share the highest amino acid sequence homology, they perform distinct functions; IL-17A is involved in the development of autoimmunity, inflammation, and tumors, and also plays important roles in the host defens...

background: asthma is the main reason of disability, health resource exploitation and low quality of life for those who are affected. it is estimated that nearly 300 million people in the world are suffering from asthma. studies have identified 18 genomic regions and more than 100 genes associated with asthma. among these candidate genes, il-17f plays a very interesting role in asthma. this stu...

Th17 cells are a distinct lineage of effector CD4(+) T cells characterized by their production of interleukin (IL)-17. We demonstrate that Th17 cells also expressed IL-22, an IL-10 family member, at substantially higher amounts than T helper (Th)1 or Th2 cells. Similar to IL-17A, IL-22 expression was initiated by transforming growth factor beta signaling in the context of IL-6 and other proinfl...
