PEGylated Galanin Shows Enhanced Analgesic Effects in PNS

Galanin is a naturally occurring neuropeptide in the human body that facilitates communication between cells to balance a myriad of physiological functions. Neuropeptides are biosynthesized molecules used by the human body for everything from neurogenesis to cell communication.  Galanin’s main receptor sites reside in the central nervous system (CNS), and it normally crosses the blood brain barrier; however, the peripheral nervous system (PNS) also reacts directly to galanin and its receptors in sites of pain mediation.1  Continue reading
