Sympathetic control of regional cardiac function occurs through postganglionic innervation from stellate ganglia and thoracic sympathetic chain. Neuropeptide Y. Neuropeptide Y ( NPY) is a 36 amino-acid neuropeptide that is involved in various physiological and homeostatic processes in both the central and peripheral nervous systems. There is growing evidence that neuropeptides, including neuropeptide Y (NPY), act as neuronal messengers in the brain and have diverse neurobehavioral functions. NPY is abundant in cerebral cortex, hippocampus, thalamus, brainstem, and hypothalamus, where it is colocalized with agouti-related protein (AgRP), and positively modulates food intake. Neuropeptide Y (NPY), one of the most abundant neuropeptides in the body, is widely expressed in the central and peripheral nervous systems and acts on the cardiovascular, digestive, endocrine, and nervous systems. Whereas norepinephrine (NE) is their primary neurotransmitter, neuropeptide Y (NPY) is an abundant cardiac cotransmitter. The . Ther.

Blocking /silencing Y2R abrogated NPY-induced angiogenic potential of CEC. Increasing evidence suggests that NPY has pronounced anti-inflammatory effects, which might depend on the inhibition of dipeptidyl-peptidase-IV (DPP-IV). Neuropeptide Y (NPY) is a major transmitter that is linked to the regulation of stress and anxiety, and has been recognized as a "stress resilience factor" in humans and rodents. . Therefore, a combination of these two new targets can be considered as a unique approach for the further development of new compounds for the treatment of anxiety disorder. Since its discovery, NPY has been implicated in metabolic regulation and, although interest in its role in central mechanisms related to food intake and obesity has somewhat diminished, the topic remains a strong focus of research concerning NPY signalling. A recent report found deceased CSF concentrations of NPY in patients with treatment resistant unipolar major depression (Heilig et al 2004).
