Since the early days, the field of neuropeptide biology has dramatically widened, and today the ultimate frontiers in neuropeptide research lie in the development of pharmacologically active compounds that are capable of crossing the blood-brain barrier to exert their biological role(s) "in vivo" and in the construction of genetic vectors to be employed in gene therapy. "Neuropeptides: Methods and Protocols" presents a readily reproducible collection of established and emerging techniques for neuropeptide research as contributed by expert researchers in the field.
