Abstract: | The molecular mechanisms underlying Ca2+ entry evoked by cell surface receptors in smooth muscle have long been enigmatic, but an important breakthrough has been made by recent investigations on mammalian homologues of Drosophila transient receptor potential (TRP) protein. There is now growing evidence that TRPC6 plays an integrative role in vascular tone regulation, Ca2+ entry channels activated by the sympathetic nerve stimulation, vasoactive peptides, and mechanosensitive mechanisms. Other TRPC isoforms, such as TRPC1 and TRPC4 (and perhaps TRPC5), are also expressed abundantly in smooth muscle and may contribute to muscle contraction, cell proliferation, and cholinergic control of the gut motility. This paper briefly overviews the current knowledge about these TRP proteins in smooth muscle physiology. |
