a9b1 Integrin-Mediated Signaling Serves as an Intrinsic Regulator of Pathogenic Th17 Cell Generation
The interaction between matricellular proteins such as tenascin-C (TN-C) and osteopontin (OPN) and integrins has been implicated in the pathology of rheumatoid arthritis in which Th17 cells are recognized as primary pathogenic cells. The differentiation of Th17 cells is tightly regulated by cytokines derived from APCs, receiving various signals including TLR stimuli. In this study, we used a co...
Dipeptidylpeptidase IV (CD26) is a multifunctional ectoenzyme involved in T cell activation that has been implicated in autoimmune pathophysiology. Because IL-17-producing CD4(+) T cells (Th17 cells) are important mediators of autoimmune disease, we analyzed the expression of CD26 and its enzymatic function on human Th17 cells. Analysis of CD26 expression on different CD4(+) T helper subsets sh...
IL-17A-producing T cells and associated cytokines are involved in the progression of gastric cancer.
Interleukin-17A-producing T cells (IL-17A+ T) (IL-17A+CD4+ Th17, IL-17A+CD8+ Tc17 and IL-17A+ γδT17 cells) and associated cytokines (IL-17A, IL-23 and IL-1β) play crucial roles in inflammation-associated diseases, such as infection, autoimmunity and tumors. Th17 cells promote human gastric cancer (GC), although the source of intracellular IL‑17A and the roles of Tc17 and γδT17 cells remain poor...
T-helper 17 (Th17) cells are characterized by producing interleukin-17 (IL-17, also called IL-17A), IL-17F, IL-21, and IL-22 and potentially TNF- α and IL-6 upon certain stimulation. IL-23, which promotes Th17 cell development, as well as IL-17 and IL-22 produced by the Th17 cells plays essential roles in various inflammatory diseases, such as experimental autoimmune encephalomyelitis, rheumato...
RORγt and RORα are transcription factors of the RAR-related orphan nuclear receptor (ROR) family. They are expressed in Th17 cells and have been suggested to play a role in Th17 differentiation. Although RORγt signature genes have been characterized in mouse Th17 cells, detailed information on its transcriptional control in human Th17 cells is limited and even less is known about RORα signature...
BACKGROUND Recently, CD4(+)IL-17A(+) T helper 17 (Th17) cells were identified and reported in several diseased states, including autoimmunity, infection and various peripheral nervous system tumors. However, the presence of Th17 in glia-derived tumors of the central nervous system has not been studied. METHODOLOGY/PRINCIPAL FINDINGS In this report, we demonstrate that mRNA expression for the ...
Th17 cell differentiation is dependent on interleukin (IL)-6 and transforming growth factor (TGF)-beta, and it is modulated by activation of the aryl hydrocarbon receptor (AhR). In this study, we show that differentiation of Th17 cells, but not Th1 or induced regulatory T (iT reg) cells, is increased by endogenous AhR agonists present in culture medium. Th17 development from wild-type mice is s...
Severe aplastic anemia (SAA) is a hematologic disease characterized by peripheral pancytopenia with bone marrow failure. Fatal bacterial or invasive fungal infections are the most frequent cause of mortality in SAA. Th17 cells are a recently discovered CD4+ T-helper subset that secrete cytokines such as interleukin 17A (IL-17A) and subsequently provide protective immunity against infections and...
T helper 17 (TH17) cells represent a discrete TH cell subset instrumental in the immune response to extracellular bacteria and fungi. However, TH17 cells are considered to be detrimentally involved in autoimmune diseases like multiple sclerosis (MS). In contrast to TH17 cells, regulatory T (Treg) cells were shown to be pivotal in the maintenance of peripheral tolerance. Thus, the balance betwee...
Experimental autoimmune uveitis (EAU) serves as a model for human autoimmune uveitis and for cell-mediated autoimmunity in general. EAU induced in mice by immunization with the retinal Ag interphotoreceptor retinoid-binding protein in CFA is driven by the Th17 response. Oral calcitriol (1,25-dihydroxyvitamin D(3)) prevented as well as partly reversed disease and suppressed immunological respons...
