Cytokines allow cells to communicate with one another and induce a wide range of activities. They can be pro- or anti-inflammatory, promote cell growth, or influence differentiation to various cell types. To mediate these functions, cytokines bind to their respective receptors on the cell surface, initiating signaling cascades for gene transcription. For example, Naïve CD4+ T cells can give rise to a number of T helper classes, depending on the recombinant proteins used to induce differentiation. Learn more about cytokines in T helper cell fates.
