From Wikipedia, the free encyclopedia. Dendritic cells (DCs) are antigen-presenting cells (also known as accessory cells) of the mammalian immune system. Their main function is to process antigen material and present it on the cell surface to the T cells of the immune system.
What are Dendrites? By Morgan Gallagher on Saturday, January 29th, 2011 Have you ever heard a Metallurgist or a Welding Engineer talk about a dendritic structure, or secondary dendrite arm spacing, and wondered what those terms meant? When metals solidify, the solid/liquid interface in most cases is not planar; rather âfingersâ of solid jut forward ahead of the solidifying interface. These fingers are dendrites, which in turn become the subgrain structure in the solidified metal. The term dendrite is derived from the Greek word dendron, meaning âtreeâ. It is easy to see how this term is appropriate in the SEM image below (âWelding: Solidification and Microstructureâ by David, Babu, and Vitek (JOM 6/03)), where the dendrites of a Ni-based superalloy, growing towards the viewer, resemble the birds eye view of a pine forest.
