Cytokines and growth factors are signaling molecules secreted by various cells of the immune system that play critical roles in regulating immune responses and inflammation. Cytokines and growth factors can act on a variety of different cell types depending on their specific function and target and they are involved in a wide range of functions, including cell growth and differentiation, inflammation, and the coordination of immune responses to pathogens. Research on cytokines and growth factors has contributed significantly to our understanding of the immune system and its role in disease in areas such as autoimmune disease, infectious diseases, developing cytokine-based therapies and vaccines.
