Moreover, the dendritic cells directly activated both the subset of helper T cells as well as the killer T cells. Once activated by dendritic cells, the T cells could also interact vigorously with other antigen presenting B cells and macrophages to produce additional immune responses from these cells. The term accessory has since been replaced by the terms professional and co-stimulatory, but the basic concept is unchanged.
What are Dendritic Cells? Dendritic cells are a type of antigen-presenting cell (APC) that form an important role in the adaptive immune system. The main function of dendritic cells is to present antigens and the cells are therefore sometimes referred to as âprofessionalâ APCs. In addition, only the dendritic cells have the capacity to induce a primary immune response in the inactive or resting naÃ¯ve T lymphocytes.
