immunity, inflammation, and hematopoiesis
Cytokines are signaling molecules secreted by a variety of cells in the immune system including macrophages, B cells, T cells, and others. They play a critical role in regulating the immune response and mediating communication between different types of immune cells.
Cytokines can have both stimulatory and inhibitory effects on immune cells, and their overall effects depend on the specific cytokine and the context in which it is produced and received. For example, some cytokines such as IL-2 and IL-12 promote T cell activation and survival, while others such as IL-10 and TGF-beta can inhibit the immune response.
In addition to their immune regulatory functions, cytokines also have many other important biological roles. For instance, they help to coordinate tissue repair and wound healing, promote hematopoiesis, and contribute to the regulation of various physiological processes such as metabolism and sleep.
Overall, cytokines are incredibly important molecules in the immune system and beyond, and understanding their functions is crucial for our understanding of immunity and other physiological processes.
