摘要: Neuropeptide Y (NPY136), a sympathetic cotransmitter and neurohormone, has pleiotropic activities ranging from the control of obesity to anxiolysis cardiovascular function. Its actions are mediated by multiple Gi/o-coupled receptors (Y1Y5) modulated dipeptidyl peptidase IV (DPPIV/cd26), which inactivates NPY's Y1-agonistic activity but generates Y2 Y5-agonist, NPY336. Released activity, NPY is major mediator stress, responsible for prolonged vasoconstriction via Y1 receptors. also mediate potent vascular growth-promoting leading in vivo rodents neointima formation. This association polymorphism signal peptide with increased lipidemia carotid artery thickening humans strongly suggest role atherosclerosis. DPPIV/cd26 coexpressed endothelium, where activates angiogenesis. A similar system exists immune cells, coactivated in...
