This article aims to provide a broad coverage of over 300 studies on T helper 17 (Th17) cells published mainly between 2011 and 2016, with a focus on factors negatively regulating Th17 cell differentiation and functions. During the last decade, processes underlying Th17 cell differentiation and activation, as well as Th17specific cytokines, chemokines, and transcription factors, have been chara...

Identification of CD4+Foxp3+ Tregs and Th17 modified the historical Th1-Th2 paradigm. Currently, the Th17-Tregs dichotomy provides a dominant conceptual framework for the comprehension of immunity/inflammation and tolerance/immunosuppression in an increasing number of diseases. Targeting proinflammatory Th17 cells or immunosuppressive Tregs has been widely considered as a promising therapeutic ...

Recent data indicate that there are different subpopulations of Th17 cells that can express a regulatory as opposed to an inflammatory gene signature. The transmembrane glycoprotein PDPN is critical in the development of multiple organs including the lymphatic system and has been described on T cells in mouse models of autoimmune Th17 inflammation. Here, we demonstrate that unlike in mice, PDPN...

IL-17-producing helper T (Th17) cells are critical for host defense against extracellular pathogens but also drive numerous autoimmune diseases. Th17 cells that differ in their inflammatory potential have been described including IL-10-producing Th17 cells that are weak inducers of inflammation and highly inflammatory, IL-23-driven, GM-CSF/IFNγ-producing Th17 cells. However, their distinct deve...

Objective: In Persian medicine (PM), wet-cupping therapy (WCT) is the most utilized approach. WCT is mostly done between the shoulders, which is referred to as “hejamt-e-aam” in the Persian language. CD4+T cells also refer to T helper lymphocytes play a critical role in the immune system. Naïve CD4+ T cells differentiate into at least four subsets, T helper 1 (Th1), T helper 2 (Th2), T helper 1...

In chronic hepatitis B virus (HBV)-infected patients, T helper 17 (Th17) cells are significantly elevated. Th17 cells initiate immune‑mediated pathogenesis and have a critical role in the process of HBV‑related liver cirrhosis (HBV‑LC). The mechanisms underlying this process are attributed to Th17‑secreted cytokines, which include interleukin (IL)‑17, IL‑21 and IL‑22; however, a systemic analys...

Recent reports have shown that IL-17-producing CD4+ T cells (Th17 cells) belong to a distinct helper T cell lineage and are critically involved in the pathogenesis of autoimmune diseases and allergies. However, the chemokine receptor profile of Th17 cells remains to be clarified. In this study, we report that human Th17 cells are identified as CCR2+CCR5- memory CD4+ T cells. Analysis of PBMC fr...

Th17 cells reactive to the enteric microbiota are central to the pathogenesis of certain types of inflammatory bowel disease. However, Th17 cells display substantial developmental plasticity, such that some progeny of Th17 cell precursors retain a predominantly IL-17A(+) phenotype, whereas others extinguish IL-17 expression and acquire expression of IFN-γ, giving rise to "Th1-like" cells. It re...

Until recently, effector T helper (Th) cells have been classified into two subsets, Th1 and Th2 cells. Since the discovery of Th17 cells, which produce IL-17, much attention has been given to Th17 cells, mainly because they have been implicated in the pathogenesis of various inflammatory diseases. We have performed transcriptome analysis combined with factor analysis and revealed that the expre...
