It is a question of interest whether Th17 cells express trafficking receptors unique to this Th cell lineage and migrate specifically to certain tissue sites. We found several Th17 cell subsets at different developing stages in a human secondary lymphoid organ (tonsils) and adult, but not in neonatal, blood. These Th17 cell subsets include a novel in vivo-stimulated tonsil IL17+ T cell subset d...
Th17 cells play an active role in autoimmune diseases. However, the nature of Th17 cells is poorly understood in cancer patients. We studied Th17 cells, the associated mechanisms, and clinical significance in 201 ovarian cancer patients. Tumor-infiltrating Th17 cells exhibit a polyfunctional effector T-cell phenotype, are positively associated with effector cells, and are negatively associated ...
IL-27 counters the effect of TGF-beta+IL-6 on naive CD4(+) T cells, resulting in near complete inhibition of de novo Th17 development. In contrast, little is known about the effect of IL-27 on already differentiated Th17 cells. A better understanding of how IL-27 regulates these cells is needed to evaluate the therapeutic potential of IL-27 in Th17 cells-associated diseases. In this study, we s...
CD4+ T-helper cells producing interleukin-17 (IL-17), known as T-helper 17 (TH17) cells, comprise heterogeneous subsets that exhibit distinct pathogenicity. Although pathogenic and non-pathogenic TH17 subsets share a common RORγt-dependent TH17 transcriptional programme, transcriptional regulatory mechanisms specific to each of these subsets are mostly unknown. Here we show that the AP-1 transc...
our previous study reported that lactobacillus acidophilus ( l.acidophilus ) key laboratory of dairy science (klds) 1.0738 had an effective impact on inhibiting β-lactoglobulin (β-lg) allergy. this study further investigated the anti-allergic activity of peptidoglycan (pgn) isolated from klds 1.0738. this study aimed to assess whether toll-like receptor 2 (tlr2)/nf-kappab (nf-κb) signaling ac...
The Th17 lineage, a lineage of effector CD4 T cells, is characterized by the production of IL-17. Expansion of Th17 cells has been implicated in a growing list of autoimmune disorders. Our studies, as well as others, have shown that Th17 cells play a key role in the pathogenesis of SLE. Therefore, some investigators advocate that Th17 cells are a promising therapeutic target for SLE. However, n...
OBJECTIVE CD4(+)CD25(+) regulatory T (Treg) cells and Th17 cells play important roles in peripheral immunity. Oxidized low-density lipoprotein (ox-LDL) is an instrumental factor in atherogenesis. However, the changes of Th17/Treg cells in patients with acute cerebral Infarction (ACI) and impact on Th17/Treg by ox-LDL are not clear. Here, we examined the balance of Th17/Treg in ACI patients and ...
the t helper 17 (th17) cells have been suggested to have osteoclast activating effects while t helper 2 (th2) cells are considered to have an osteoprotective role in periodontitis. this study was to compare the markers of th17 cells (rorc2 and il-17 genes) with that of th2 cells (il-4 and gata-3 genes) between healthy and periodontitis tissues.the samples were obtained from patients with period...
Th17 and regulatory T (Treg) cells play opposite roles in autoimmune diseases. However, the mechanisms underlying their proper migration to inflammatory tissues are unclear. In this study, we report that these two T cell subsets both express CCR6. CCR6 expression in Th17 cells is regulated by TGF-beta and requires two nuclear receptors, RORalpha and RORgamma. Th17 cells also express the CCR6 li...
