    These are taken up by cells throughout the body called antigen-presenting cells, such as dendritic cells. [28] These antigen presenting cells enter the lymph system and then lymph nodes. They present the antigen to T cells and, if there is a T cell with the appropriate T cell receptor, it will be activated.
