Distribution, pharmacology, molecular identity and roles of purine receptors in enteric neurons

Abstract

Digestive function needs to be adapted to the great variety of foods that we eat, and to our variable dietary habits. Adaptation is controlled through an extensive nervous system in the wall of the gastrointestinal tract, the enteric nervous system, and through digestive system hormones. The enteric nervous system detects the volume and key chemical components in the gastrointestinal lumen and, through an integrating nerve circuitry, causes changes in the patterns of movement, fluid secretion and local blood flow. Digestive system diseases, for example irritable bowel syndrome, can involve disordered function of the enteric nervous system, and there is considerable research and development f..
