Dendritic cell and T-lymphocytes, illustration - stock illustration

Illustration of a dendritic cell (centre) presenting an antigen to T-lymphocytes. Both cells are components of the bodys 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.
