WebCD4+T helper cells are key regulators of host health and disease. In the original model, specialized subsets of T helper cells are generated following activation through lineage-specifying cytokines and transcriptional programs, but recent studies have revealed increasing complexities for CD4+T-cell differentiation. WebTwo transcription factors have been found that play a critical role in the choice between becoming a Th1 or a Th2 cell.. T-bet for Th1 cells ; GATA3 for Th2 cells . T-bet produces Th1 cells by turning on the genes needed for Th1 function (e.g., for IFN-γ) blocking the activity of GATA3. Mice whose genes for T-bet have been "knocked-out" lack Th1 cells …

WebAbstract. T lymphocytes, the major effector cells in cellular immunity, produce cytokines in immune responses to mediate inflammation and regulate other types of immune cells. … WebHelper T-cells aid other cells in the immune response. When they sense an infection, they release cytokines, molecules that send messages to other immune cells. These cytokines help activate cytotoxic T-cells to fight the infection.

Helper T cell differentiation - PubMed

WebHelper T cells located in follicles within lymph nodes act on B cells to regulate the affinity and class of antibodies they produce. They are called Tfh cells. Mice and humans actively producing IgE rely on a subset of Tfh cells that produce IL-13 in large amounts. They are required for the production of high-affinity IgE and are essential for ... WebThe specific cytokines present during the process of helper T cellactivation influence the type of effector cellproduced. Microbes at a site of infection not only stimulate dendritic cells to make cell-surface B7 costimulatory … WebAlthough pDHSs arise prior to helper T cell differentiation, some of these pDHSs, such as those seen in the Th2 cytokine gene locus, ... Long-term immunological memory in CD4 T cells is dependent on cytokine and TNFSF networks involving interleukin 7 (IL-7) and OX40 that maintain the rapid recall response in CD4 memory T cells.
