T- cells

T-cells are a type of white blood cell that circulates around our bodies, scanning for cellular abnormalities and infections. T-cells are essential for human immunity.

There are several different kinds of T-cell; broadly speaking they can be divided into two different types, killer T-cells and helper T-cells.
