Hypothalamic Neurotensin Neurons represent a specialized population of neurons in the hypothalamus that produce and release neurotensin, a 13-amino acid neuropeptide with diverse physiological functions. These neurons play crucial roles in modulating pain perception, dopamine signaling, body temperature regulation, and have emerging connections to neurodegenerative disease processes.

Overview
Mermaid diagram (expand to render)
Neurotensin is a neuropeptide found in hypothalamic neurons that modulates pain, dopamine signaling, and body temperature. The hypothalamus contains distinct populations of neurotensin-expressing neurons that project to various brain regions and regulate multiple physiological systems. [@neurotensin2021]
