Nerves and Skin

I just discovered a large review article: Neuronal Control of Skin Function: The Skin as a Neuroimmunoendocrine Organ by Dirk Roosterman, Tobias Goerge, Stefan W. Schneider, Nigel W. Bunnett and Martin Steinhoff. For some reason, it's open access, despite being a very large and recent. I haven't read it yet (just the first few para's), so I'll add comments as they occur to me.
