WebAs the authors show, these channels and transporters play crucial roles in transepithelial ion and fluid transport across epithelia and their contribution to maintaining homeostasis. Readers will be introduced to the fundamentals of ion transport in terms of function, modelling, regulation, structure and pharmacology. WebIon channels have been divided into families based on their structure, the primary ion they transport, and the mechanism(s) that trigger their opening or activation. They can been …
WebBook excerpt: Ion channels are membrane proteins that act as gated pathways for the movement of ions across cell membranes. They play essential roles in the physiology of all cells. In recent years, an ever-increasing number of human and animal diseases have been found to result from defects in ion channel function. WebAbstract: Ion channels, which are found in every biological cell, regulate the concentration of electrolytes, and are responsible for multiple biological functions, including in particular the propagation of nerve impulses. The channels with the latter function are gated (opened) by a voltage signal, which allows Na+ into the cell and K+ out.
