Produced by many immune and nonimmune cells, all ______ are small proteins that bind to and activate receptors located on target cells and low molecular weight. Cytokine secretion (not stored) is a brief, self-limited event. Cytokines link the components of the immune system together. They are the chemical communication network that allows different immune system cells to “talk” to one another. This is called cross talk, and it is essential for the precise timing of the functions of the immune system. Most ______ are secreted by more than one type of immune system cell and also by certain nonimmune cells (for example, by endothelial cells and fibroblasts). Cytokines may have both protective and deleterious effects on the host.
