Dendritic cells are immune cells that form part of the mammalian immune system.
Their main function is to process antigen material and present it on the surface to other cells of the immune system, thus functioning as antigen-presenting cells.
Dendritic cells are present in small quantities in tissues that are in contact with the external environment , mainly the skin (where there is a specialized dendritic cell type called Langerhans cells) and the inner lining of the nose, lungs, stomach and intestines.
