Helper T cells are the mediators of the immune system, they carry information and decide when to give the green light to other immune cells to carry out an immune response. Helper T cells can only bind to swallowing cells like the macrophage and the B cell. cells are like the police chiefs of white blood cells. T cells are white blood cells called lymphocytes. There are many different types of T cells that all perform different functions, but among the most important are Helper T cells and Killer T cells.
If innate immune cells (dendritic cells) decide that the material is dangerous (part of a virus or bacteria), then they stimulate a specialized group of white blood cells causes CD4 + helper T cells to become activated. CD4 + refers to a surface protein on this class of T cells. Helper T cells can stimulate another group of white blood cells called B cells to produce antibodies that bind that specific antigen and immobilize it, preventing it from causing infection. Antibodies are specific for only one antigen.
