Abstract:
For a long time research on the action of TKs on gastrointestinal tissue has been demonstrating the importance of the TKs as non-cholinergic stimulators of motility in most parts of the mammalian gastrointestinal tract. The past years witnessed the development of TK agonists and antagonists selective for the various receptor types, which prompted a wealth of new insight into the pharmacology and molecular biology of the TK receptors. This knowledge now allows a more specific elucidation of the role of TKs and their receptors in the various aspects of gastrointestinal motility, not only in normal tissue but also under pathological conditions.
Insights
Tachykinins (TKs) are crucial non-cholinergic stimulators of mammalian gastrointestinal motility. Recent advances in TK receptor pharmacology and molecular biology offer new insights into their roles in both normal and diseased states.
