Intracerebroventricular (I.C.V.) administration of an inhibitor of nitric oxide synthase (NOS) increases oxytocin but not vasopressin secretion, in dehydrated rats [38]. Surprisingly, central injection of L-arginine, the substrate for NOS, caused a similar effect. Kyotorphin (L-tyrosyl-L-arginine), a dipeptide formed from

High-affinity type H+/peptide cotransporter PEPT2 is preferentially expressed in the kidney, and is responsible for reabsorption of di- and tripeptides in epithelial tubules. Interestingly, PEPT2 has been recently cloned from rat brain. However, there is very little information available on

It is generally accepted that morphine exerts its analgesic effect by binding to specific opiate receptors in the brain and spinal cord. Since Hughes et al. isolated and identified two endogenous pentapeptides, Met- and Leu-enkephalin, from the brain and found

Although we have obtained a number of pharmacological tools and mutant mice lacking specific genes related to the pain, the distinct molecular basis of the pain-producing mechanism has remained to be fully clarified since we have been using conventional paradigms

The intraplantar injection of kyotorphin (Kyo) elicited nociceptive flexor responses in mice in a dose-dependent manner between 0.1 and 100 fmol. These actions were completely blocked by substance P (NK1) receptor antagonists, such as CP-96345 and CP-99994, but not by
