NCIt definition : Immunocompetent cells of the lymphoid and hemopoietic systems and skin. They function
morphologically and phenotypically by presenting or processing antigens, thereby stimulating
cellular immunity. They represent the most potent antigen-presenting cells and, therefore,
play a critical role in the primary T cell immune response.;
Alternative definition : NCI-GLOSS: A special type of immune cell that is found in tissues, such as the skin,
and boosts immune responses by showing antigens on its surface to other cells of the
immune system. A dendritic cell is a type of phagocyte and a type of antigen-presenting
cell (APC).;
