The term cytokine is derived from a combination of two Greek words - cyto meaning cell and kinos meaning movement. Cytokines are cell signalling molecules that aid cell to cell communication in immune responses and stimulate the movement of cells towards sites of inflammation, infection and trauma.
They are secreted primarily by white blood cells, T lymphocytes, and epithelial cells. There are two general groupings of cytokines based on the effect they have on lymphocytes: Th1 and Th2. The balance between Th1 and Th2 determines the type of immune response and the resultant health or disease that results.
