Reassigning cells to fight infection

Just as a uniform helps distinguish a soldier from a police officer, scientists use proteins that immune cells wear on their surfaces to determine their job in the body. T cells, for example, that display ...

T cell

T cells belong to a group of white blood cells known as lymphocytes, and play a central role in cell-mediated immunity. They can be distinguished from other lymphocyte types, such as B cells and natural killer cells by the presence of a special receptor on their cell surface called T cell receptors (TCR). The abbreviation T, in T cell, stands for thymus, since this is the principal organ responsible for the T cell's maturation. Several different subsets of T cells have been discovered, each with a distinct function.
