More Description

The general characteristics of neuropeptides are discussed as a background for the understanding of their role in regulation of physiological systems. The extent of those systems that are crucially affected by neuropeptides is vast and the complexity of their interactions makes the clinical focus on a specific neu­ ropeptide unsatisfactory. The clinical potential of neuropeptides affecting eating disorders, eNS behavioral disorders and the neuroregenerative and neuroprotective action of neuropeptides is discussed. It is probable that suc­ cessful neuropeptide therapeutics will depend upon the application of trans­ lational and combinational research using various ingenious combinations and antagonists, neuropeptide receptor ago­ of neuropeptides, their agonists nists and antagonists, improved methods of delivery and the development of peptides targeted to the genetic profile of individual patients.
