Localization Of Neuropeptide Y Y₁ Receptor In Heart And Vessels And Its Distribution In Cerebral Arteries Of The Simulated Weightlessness Rats

The sympathetic nerve plays an important role in the cardiovascular regulatory function. Noradrenaline is considered to be the classic transmitter of the sympathetic nerve, but adenosine triphosphate and Neuropeptide Y (NPY) as cotransmitters. They are all involved in cardiovascular regulation. NPY is a 36-amino acid peptide found in both the central and peripheral nervous systems. Until now the functions of NPY on cardiovascular regulation have been widely investigated.
