Summary
Neuropeptide Y (NPY) regulates food intake, neuroendocrine axes, and blood vessel constriction. Its diverse roles suggest potential therapeutic applications for obesity, metabolic disorders, and cardiovascular diseases.
Area of Science:
- Endocrinology
- Neuroscience
- Cardiovascular Physiology
Background:
- Neuropeptide Y (NPY) is a peptide neurotransmitter implicated in regulating multiple physiological systems.
- NPY plays a key role in hypothalamic control of appetite and neuroendocrine function, particularly during metabolic stress.
Purpose of the Study:
- To review the multifaceted roles of Neuropeptide Y (NPY) in physiological regulation.
- To highlight NPY's potential as a therapeutic target for various human diseases.
Main Methods:
- Literature review of studies investigating NPY's physiological functions.
- Analysis of NPY's involvement in appetite regulation, neuroendocrine axes, vascular function, and cardiovascular remodeling.
Main Results:
- NPY is central to appetite regulation in the hypothalamus.
- NPY influences neuroendocrine axes activity under metabolic challenge.
- NPY exhibits vasoconstrictive properties and trophic effects, contributing to cardiovascular remodeling.
Conclusions:
- Neuropeptide Y (NPY) possesses diverse physiological functions, including appetite control, neuroendocrine regulation, and cardiovascular effects.
- NPY's multifaceted actions position it as a promising therapeutic target for obesity, metabolic disorders, hypertension, and heart failure.
