A chemokine is a special type of cytokine whose main objective is to guide the white blood cells to the affected area, a process which is known as chemotaxis. The white blood cells, along with lymphocytes, destroy any foreign microorganisms that may be causing the infection.

What are Cytokines? Cytokines represent a diverse collection of chemical mediators that function as cellular molecular messengers. They are proteins produced by immune cells (not stored but secreted rapidly and briefly) that, when released either into the blood stream or localized tissue, activate or trigger a response in a target immune cell by binding to receptors on it. Lymphoid organs are the professional sites in the body that allow lymphocytes to encounter antigen, become activated and proliferate.
