WebOne specific type of cytokine is called a chemokine. A chemokine can make immune cells move toward a target. There are different kinds of chemokines, including interleukins, interferons, tumor necrosis factors, and growth factors. Some cytokines can be made in a lab and are used to treat cancer. WebFor example, cytokines can direct immune cells toward an infection site so the cells can fight germs there. They can heighten or lessen the processes associated with inflammation. Cell differentiation: Cytokines can tell immature cells to develop into a specific type of cell.
