Neurotensin
Neurotensin
Neurotensin (pronounced: noor-oh-TEN-sin) is a 13 amino acid neuropeptide that is found in the central nervous system and in the gastrointestinal tract. It was first isolated in 1973 from bovine hypothalami.
Etymology
The term "neurotensin" is derived from the words "neuro", referring to the nervous system, and "tensin", indicating its tension or pressure-related functions.
Function
Neurotensin is involved in a variety of physiological processes, including the regulation of dopamine activity, pain modulation, and the regulation of body temperature. It also has a role in the regulation of gastrointestinal motility and secretion.
