Neuroendocrine modulation of the inflammatory response in common carp: Adrenaline regulates leukocyte profile and activity

► Stress mediators act as regulators of inflammation. ► Adrenaline induces apoptosis of macrophages in the focus of inflammation. ► Adrenaline reduces gene expression of chemokines and their receptors. ► Adrenaline thus contributes to a balanced immune response during stress.
