Cytokines and Their Functions

Cytokines are a group of small proteins that act as signaling molecules, playing an important role in the immune system by regulating the interaction, growth, and differentiation of cells. Their functions are diverse and include regulating inflammation, triggering innate and adaptive immunity, and even modulating cell death. Cytokines are also involved in a multitude of complex cellular processes, such as developing inflammation, maintaining tissue integrity and homeostasis, and influencing the behavior of many different types of cells. Their effects are crucial for the maintenance of health and the prevention of diseases. As such, they represent a promising target for therapeutic applications, such as treating autoimmune and inflammatory diseases, allergies, cancer, and infectious diseases.
