How to increaseneurotensin Neurotensin peptide is a fascinating molecule that plays a significant role in both the central nervous system (CNS) and the gastrointestinal tract. Primarily known as a 13 amino acid neuropeptide, it is also described as a peptide of 13 amino acids and an endogenous tridecapeptide neurotransmitter. Its complex functions have garnered considerable attention in neuroscience and endocrinology, leading to its exploration for various physiological processes and potential therapeutic applications.作者：S Crunkhorn·2016·被引用次数：2—NT is a 13-amino-acid peptidelocated in enteroendocrine cells of the small intestine, where it is released by fat ingestion to facilitate fatty ...

First isolated from bovine hypothalamus, neurotensin is a peptide hormone and a neurotransmitter-like hypothalamic peptide. Its distribution is widespread, as it is widely distributed in the brain and gastrointestinal tract. This dual localization allows it to exert both central and peripheral effects through interaction with specific receptorsNeurotensin.

Understanding the Structure and Origin of Neurotensin

The precise sequence of neurotensin peptide is characterized by 13 amino acids, with the sequence often represented as pGlu-Leu-Tyr-Glu-Asn-Lys-Pro-Arg-Arg-Pro-Tyr-Ile-Leu-OH. Its molecular weight is a key parameter, with estimations such as Molecular Weight: 816.Neurotensin (8-13); [60482-95-3]51 for specific forms like Neurotensin (8-13).Neurotensin Peptide In terms of its production, neurotensin is primarily synthesized by endocrine cells of the ileal mucosa. The description "Source, Synthetic" also highlights its availability for research purposes through chemical synthesis, often with a purity exceeding 95%.

Physiological Functions of Neurotensin Peptide

Neurotensin fulfills a dual function, acting as a neuromodulator in the brain and a hormone in the gastrointestinal tract. Its physiological actions are diverse and include:

* Regulation of Hormone Release: Neurotensin peptide is implicated in the regulation of luteinizing hormone and prolactin release.

* Cardiovascular Effects: It is known to lower blood pressure and increases vascular permeability.

* Metabolic Regulation: Neurotensin plays a role in the regulation of luteinizing hormone and prolactin release, and NTS is anti-thermogenic, suggesting a function in energy balance and thermoregulation.Neurotensin (8-13) It is also suggested to have an endocrine or paracrine role in the regulation of fat metabolism, as NT is a 13-amino-acid peptide located in enteroendocrine cells of the small intestine, where it is released by fat ingestion to facilitate fatty acid absorption. Recent research, such as studies in 2023, further emphasizes neurotensin and energy balance, and its role in body temperature regulation and temperature perception, key components of maintaining homeostasis.

* Neurotransmitter Modulation: Neurotensin can act as a neuromodulator of dopamine transmission.

* Gastrointestinal Functions: It stimulates the contraction of smooth muscle and is released by dietary fat intake.

* Central Nervous System Effects: Neurotensin has been shown to possess analgesic, hypothermic, and antipsychotic-like propertiesNTS - Neurotensin/neuromedin N - Homo sapiens (Human). Its ability to cross the blood-brain barrier is an area of ongoing research, with efforts to develop neurotensin peptide analogue NT-20.3 for potential applications in neurological protection.

Neurotensin Receptors and Signaling

The effects of neurotensin are mediated primarily through specific receptors. It acts on three subtypes of neurotensin receptors, most notably the G-protein-coupled receptors: NTS1 (also referred to as Ntsr1) and NTS2. Activation of NTS1, in particular, has been implicated in a wide range of neurobiological and physiological processes.

Research and Potential Applications

The multifaceted nature of neurotensin peptide makes it a subject of intense scientific investigation. Its role in various physiological and pathological processes, including its potential involvement in conditions like glucagon-like peptide-1 suppresses neuroinflammation, continues to be explored. Furthermore, its association with cancer, where Neurotensin, a gut tridecapeptide, acts as a potent cellular mitogen for various colorectal and pancreatic cancers which possess high-affinity neurotensin receptors (NTR), opens avenues for targeted therapies.Neurotensin Peptide

The availability of neurotensin for research, often synthesized by entities described as a CRDMO specializing in peptide and oligonucleotide production, facilitates these investigations. While specific products like Neurotensin (1-11) is a peptide are available, the broader scientific community continues to delve into the intricate mechanisms and therapeutic potential of the neurotensin peptide.
