OBJECTIVE Chronic low-grade inflammation has long been recognized as the central link between obesity and type 2 diabetes (T2D). The novel subset of T helper (Th) cells, Th22, plays an emerging role in chronic inflammation. We investigated the potential association between Th22 and the pathogenesis of obesity and T2D. METHODS Ninety T2D inpatients (T2D group), 30 healthy participants with BMI...

Th subsets are defined according to their production of lineage-indicating cytokines and functions. In this study, we have identified a subset of human Th cells that infiltrates the epidermis in individuals with inflammatory skin disorders and is characterized by the secretion of IL-22 and TNF-alpha, but not IFN-gamma, IL-4, or IL-17. In analogy to the Th17 subset, cells with this cytokine prof...

Th17 and Th22 cells are thought to function as innate regulators of mucosal antimicrobial responses, tissue inflammation and mucosal integrity, yet their role in persistent SIV infection is still unclear. Here we compared Th17 and Th22 cells in their phenotype, effector/cytokine function, and frequency in blood and intestinal mucosal tissues, and correlate levels with mucosal damage in SIV-infe...

The Guillain-Barré syndrome (GBS) is considered a T helper 1 (Th1) cells-mediated acute inflammatory peripheral neuropathy. However, some changes in GBS could not be explained completely by Th1 cells pathogenic role. Recently, Th17 cells have been identified and can mediate tissue inflammation and autoimmune response. Therefore, a study on the role of Th17 and Th22 cells and their cytokines in ...

BACKGROUND T-helper (Th) 22 is involved in the pathogenesis of inflammatory diseases. The roles of Th22 cells in the pathophysiological of ankylosing spondylitis (AS) and rheumatoid arthritis (RA) remain unsettled. So we examined the frequencies of Th22 cells, Th17 cells and Th1 cells in peripheral blood (PB) from patients with AS and patients with RA compared with both healthy controls as well...

BACKGROUND We have shown previously that T cells from atopic dermatitis (AD) patients produce more IL-22 upon staphylococcal exotoxin stimulation compared to psoriasis patients and healthy controls. The role of staphylococcal exotoxins on polarized memory T helper (Th)22 cells which are enriched in inflamed AD skin remains elusive. Our aim was to investigate IL-22 production in response to stap...

This study is conducted to investigate the involvement of T-helper (Th) cells and regulatory T cells in epithelial ovarian cancer (EOC).The percentages of Th22, Th17, Th1, and regulatory T cells in the peripheral blood of EOC patients, benign ovarian epithelial neoplasm (BOEN) patients, and healthy control (HC) were examined by flow cytometry. Enzyme-linked immunosorbent assay was used to deter...

Leukemia is a hematological tumor in which the malignant myeloid or lymphoid subsets play a pivotal role. Newly identified T helper cell 22 (Th22) is a subset of CD4(+) T cells with distinguished gene expression, function and specific properties apart from other known CD4(+) T cell subsets.Th22 cells are characterized by production of a distinct profile of effector cytokines, including interleu...

T-helper (Th) 22 and Th17 cells are implicated in the pathogenesis of autoimmune diseases. However, the role of Th22 cells in the pathophysiology of immune thrombocytopenia (ITP) remains unclear. Th22, Th17 and Th1 cells in both ITP patients and healthy controls were examined by flow cytometry. Plasma interleukin-22 (IL-22) level was measured by enzyme linked immunosorbent assay (ELISA). Signal...

During the last decade, the field of T cell immunology started to confuse the scientific community. More and more subtypes of T helper cells and their counterparts in the innate immune system are described. We are just at the beginning to understand which specific function the distinct subtypes fulfill. Th22 cells are terminally differentiated and very specialized T helper cells characterized b...
