The neuro-immuno-cutaneous-endocrine network is not a simple construct featuring organ systems intimately involved in the bridge between body and mind. Mind-body influences are bi-directional and the skin should be considered an active neuroimmunoendocrine interface, where effector molecules of neuropeptides act as common words used in a dynamic dialogue immune system and skin.

Alpha-melanocyte stimulating hormone (alpha-MSH), between brain, one of the principal neuroimmunomodulating peptides, seems to exercise some control on the cutaneous inflammatory process, through a central action mediated by descending anti-inflammatory neural pathways and via local direct influence on inflammatory cells infiltrating the dermis, such as monocytes, macrophages and neutrophils. alpha-MSH down-regulates the production of proinflammatory cytokines, while the production of the anti-inflammatory cytokine IL-10 is stimulated by alpha-MSH. Finally, alpha-MSH seems to regulate the expression of surface molecules in immunocompetent cells.

Thus, further studies may lead to the use of alpha-MSH as an important anti-inflammatory agent in clinical dermatology.
