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 The term accessory has since been replaced by the terms professional and co-stimulatory, but the basic concept is unchanged.
T cells (Thymus cells) and B cells (bone cells). The function of T cells and B cells is to recognize specific non-self antigens, during a process known as antigen presenta â¦ tion.Once they have identified an invader, the cells generate specific responses that are tailored to maximally eliminate specific pathogens or pathogen infected cells.n response to pathogens some T cells, called T helper cells, produce cytokines that direct the immune response while other T cells, called cytotoxic T cells, produce toxic granules that contain powerful enzymes which induce the death of pathogen infected cells.
