Computer illustration of a dendritic cell (light blue) and a t-cell (bright blue) interacting. Both cells are components of the body's immune system. Dendritic cells are antigen-presenting cells (APCs), that is, they present pathogens or foreign molecules (antigens) to other cells of the immune system to be eliminated. T-cells are activated by dendritic cells to effect an immune response.
