Like other subsets of T helper cells, Th17 cells differentiate from naive CD4+ cells in the periphery in response to T cell receptor (TCR) antigen stimulation and activating cytokines secreted by antigen-presenting cells [6]. While differentiation was originally bel...
T helper (Th) cells are CD4+T cells that play a central role in the adaptive immune system, by facilitating the activity of other immune cells – especially antigen-presenting cells (APCs) such as B cells, macrophages, anddendriticcells – through the release of cytokines and chemokines. They...
The effector function of CD4+T helper cells is mediated primarily by secreted cytokines, and the specific cytokine profile produced by each subset has been one of the main defining characteristics uses to phenotype each population [1] (Figure ...
Helper T cells constitute a specific subpopulation of CD4+ T cells that provide help to other cells of the immune system in mounting an immune response through either direct cell–cell interaction or the secretion of cytokines.

3.1T helper 1 cells (Th1) The T helper cells (Th1 cells) are a subset of CD4+T cellswhich are characterized by releasing cytokines likeinterferon gamma(IFN-γ), IL-2, andtumor necrosis factor alpha(TNF-α) to activate otherimmune cellsand contribute tocellular immune responses. The number...
Why do helper T-cells make cytokines?CytokinesCytokines play an essential role in the operation of macrophages by linking the adaptive and the innate immunity. Also, it influences the microenvironment of macrophages. Furthermore, cytokines regulate apoptosis and cell replication....
In the few years since their discovery, T helper 17 cells (TH17) have been shown to play an important role in host defense against infections, and in tissue inflammation during autoimmunity. TH17 cells produce IL-17, IL-21, IL-10, and IL-22 cytokines, and thus have broad effects on a...
T follicular helper (TFH) cells are a phenotypically distinct subset of activated T cells that specializes in promoting germinal centre reactions that support B cell proliferation, somatic hypermutation and class-switch recombination. TFH cell development is regulated by a suite of transcriptional factors...
