Neurobiology
VIP, PACAP, and three receptors that do not divide neatly
Two neuropeptides found nineteen years apart turned out to share most of a receptor family. Which receptor a study engaged is often the first thing to ask of it.
Neurobiology
Neuropeptides: ACTH fragments, a sleep factor, and VIP
Three research lines from very different places: Soviet-era clinical pharmacology, a 1977 discovery that was never settled, and a well-mapped hormone.
