Cytokines are chemical messengers that primarily signal the immune system, but also play a role as neuromodulators. They can be defined as either pro-inflammatory or anti-inflammatory. Cytokine imbalances are known to be involved in autoimmune disorders, atopic conditions as well as neuropsychiatric disorders.
Cytokines are signaling proteins and glycoproteins that mediate and regular immunity, inflammation and hematopoiesis. They are also involved in cell growth and differentiation, cell death, angiogenesis, normal development and neuromodulations.
