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.rom Wikipedia, the free encyclopedia.

Dendritic cells are also proving to be major adjuvants in cancer vaccine research. Natural killer cells (NK cells) are a type of cytotoxic T-cell that are not specific for one cancer cell type, as are the tumor specific cells produced in response to dendritic cells.riginally NK cells were thought to simply attack cancer cells when they find them and not require activation by finding a specific cancer cell marker, hence the name natural killer cells. We now know that they are activated by lack of a cell marker that identifies the cell as âselfâ that is normal to the body.
