Neuropeptide Y (NPY), a peptide with 36-amino acids, acts as a neurotransmitter in the autonomic nervous system (ANS). It is one of the most abundant neuropeptides in the central and peripheral nervous system. In the periphery, NPY is widely distributed in the adrenal medulla, in the sympathetic nerves, platelets, and various cell types within white adipose tissue. Еще
