Abstract

The tridecapeptide neurotensin (NT) (pGlu-Leu-Tyr-Glu-Asn-Lys-Pro-Arg-Arg-Pro-Tyr-Ile-Leu-OH) is thought to act as a neurotransmitter/modulator in the central nervous system (Nemeroff et al., 1982). The existence of functional specific NT receptors that exist in both high- and low-affinity states in brain tissues has been well documented (Kitabgi et al., 1985). In some cases, it has been possible to identify the neurons that bear NT receptors. For instance, there is strong evidence for the presence of somatodendritic NT receptors on dopaminergic neurons from the substantia nigra and the ventral tegmental area (Quirion, 1983). These receptors presumably mediate, at least in part, the regulatory effects that NT is thought to exert on the nigrostriatal and mesolimbic dopaminergic systems (Nemeroff and Cain, 1985).
