The neuropeptide neurotensin (NT) has been recently shown to protect pancreatic beta cells from toxic agents-induced apoptosis through interaction with the NT receptor-2 (NTSR2) and activation of the phosphatidylinositol-3 kinase pathway. However, expression of the NT receptor-3/sortilin (NTSR3) in the mouse pancreatic beta cell line -TC3 led...

Following inflammation or infection, cytokines are released in the blood. Besides their effect on the immune system, cytokines can also act in the brain to modulate our behaviors, inducing for example anorexia when produced in large amount. This review focuses on our current knowledge on how cytokines can influence the brain and the behaviors...

The pharmacological roles of the neuropeptide neurotensin through its three known receptors are various and complex. Neurotensin is involved in several important biological functions including analgesia and hypothermia in the central nervous system and also food intake and glucose homeostasis in the periphery. This review focuses on recent...

The neurotensin (NT) receptor-3 (NTSR3), also called sortilin, is thought to display several functions including a role as a receptor or a co-receptor, in the sorting to plasma membrane and to lysosomes, and in the regulated secretion. The aim of this study was to investigate the function of the soluble form of NTSR3 (sNTSR3) released from...

The neurotensin (NT) receptor-3 (NTSR3), also called sortilin is a multifunctional protein localized at the intracellular and plasma membrane level. The extracellular domain of NTSR3 (sNTSR3) is released by shedding from several cell lines including colonic cancer cells. This soluble protein acts as an active ligand through its ability to bind,...

The neurotensin hexapapetide fragment NT(8-13) is a potent analgesic when administered directly to the central nervous system but does not cross the blood-brain barrier. A total of 43 novel derivatives of NT(8-13) were evaluated, with one, ABS212 (1), being most active in four rat models of pain when administered peripherally. Compound 1 binds...
