Behçet's disease is a systemic inflammatory disorder with recurrent episodes of oral ulceration, skin lesions, genital ulceration, and intraocular inflammation (uveitis). The intraocular inflammation is strictly associated with Th effector cells. IL-22 is a member of the IL-10 cytokine family that is involved in inflammatory processes. Recently, Th22 cells were identified as a Th cell populatio...

T helper- (Th-) cell immunodeficiency plays important roles in tumor development and their effects in chronic myeloid leukemia (CML) remain unclear. In the present study, we mainly investigated the role of Th22, Th17, and Th1 cell and their related cytokines (IL-22, IL-17, and IFN-r) in the pathophysiology of CML. Bone marrow (BM) and peripheral blood (PB) were extracted from newly diagnosed (N...

Psoriasis is a common chronic inflammatory and T cell-meditated skin disease. Runt-related transcription factor 3 (RUNX3), one of the runt‑domain family of transcription factors, has been reported to be a susceptibility gene for psoriasis. The present study was designed to delineate the role and underlying mechanism of RUNX3 involved in the differentiation of T helper (Th) 17 and Th22 cells in ...

PURPOSE The aim of this study was to make a comparative analysis of the possible different expression of Th22 cells in two subtypes of autoimmune thyroid diseases (AITDs), i.e., Graves' disease (GD) and Hashimoto's thyroiditis (HT). METHODS We recruited 61 AITDs patients (31 GD and 30 HT) and 22 controls. Serum level of IL-22 was measured by enzyme linked immunosorbent assay (ELISA). The prop...

T-helper (Th) 22 and Th17 cells are involved in the pathogenesis of autoimmune diseases. However, their roles in the pathogenesis of Graves'disease (GD) are unclear. This study is aimed at examining the frequency of peripheral blood Th22, Th17, and Th1 cells and the levels of plasma IL-22, IL-17, and IFN-γ in patients with GD. A total of 27 patients with new onset GD and 27 gender- and age-matc...

newly  identified  t  helper  cell  22  (th22)  is  a  subset  of  cd4+t  cells  with  specific properties apart from other known cd4+ t cell subsets with distinguished gene expression and function. th22 cells are characterized by production of a distinct profile of effector cytokines, including interleukin (il)-22, il-13, and tumor necrosis factor-α (tnf-α). the levels of th22 and related cyto...

BACKGROUND We set out to determine the magnitude of antigen-specific memory T helper cell responses to Pseudomonas aeruginosa in healthy humans and patients with cystic fibrosis. METHODS Peripheral blood human memory CD4(+) T cells were co-cultured with dendritic cells that had been infected with different strains of Pseudomonas aeruginosa. The T helper response was determined by measuring pr...

T helper (Th) cell imbalance plays important roles in tumor development and their effects in Multiple myeloma (MM) remain unclear. In the present study, we investigated the levels and clinical significance of Th22, Th17 and Th1 cells in patients with MM. Th subsets were examined by flow cytometry. Plasma IL-22, IL-17A and IFN-γ concentrations were measured by ELISA. AHR and RORC mRNA expression...

BACKGROUND Coronary atherosclerotic heart disease (CHD) is one of the major concerns in type 2 diabetes (T2D). The systemic chronic inflammation has been postulated to bridge the increased risk of cardiovascular disease and T2D. We formulated that increased peripheral proinflammatory T helper subsets contributed to the development of cardiovascular complications in diabetic patients. METHODS ...

BACKGROUND CD4+ T helper (Th) cells play critical roles in the development and progression of atherosclerosis and the onset of acute coronary syndromes (ACS, including acute myocardial infarction (AMI) and unstable angina pectoris (UAP)). In addition to Th1, Th2, and Th17 cells, Th22 and Th9 subsets have been identified in humans. In the present study, we investigated whether Th22 cells and Th9...
