One of the proteins produced by white blood cells.

A soluble protein, produced by white blood cells, that acts as a messenger between cells, either stimulating or inhibiting the activity of various cells of the immune system. There is normally a very delicate balance among the various cytokines.

proteins (such as interleukins, tumor necrosis factor, and interferons) that are secreted by immune cells.

Messenger molecules by which the cells of the immune system communicate with one another and with other cells. Some cytokines are also used by nerve cells as messenger molecules. Cytokines play an important role in inflammation.
