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. Cytokines exist in peptide, protein and glycoprotein (proteins with a sugar attached) forms.
Cytokines are important as well since they are molecules used for signaling, and this helps to coordinate the process of inflammation between body systems and cells. Learning Outcomes.
