WebCytokine is a general term used for small secreted proteins that are key modulators of inflammation. Cytokines are produced in response to invading pathogens to stimulate, recruit, and proliferate immune cells. … WebClassification of Cytokines. Based on their actions, cytokines can be classified as follows: Chemokines are a class of cytokines that cause the cells to migrate along a chemical gradient. When the macrophages release chemokines, the cells migrate through chemotaxis and move towards the region where the concentration of chemokines is the highest ... imf fitness center
