Connexins: A Guide is a practical and valuable reference and text covering a wide scope of information about the connexin family of membrane channel proteins. The editors and contributing authors intend for this cutting-edge work to be informative to scientists wishing to learn about the field, as well as to those who are active researchers in this area. Connexins: A Guide masterfully addresses specific needs of the scientific community; it is a comprehensive and comprehensible narrative of the uncommonly diverse connexin field, making previously hard-to-find information easily accessible, while also presenting intelligible insights into the extensive experimental methods and conceptual frameworks necessary to appreciate and understand the important roles that connexin channel proteins play in health and disease.
