Connexins and cell signaling in development and disease.
Gap junctions contain hydrophilic membrane channels that allow direct communication between neighboring cells through the diffusion of ions, metabolites, and small cell signaling molecules. They are made up of a hexameric array of polypeptides encoded by the connexin multi-gene family. Cell-cell communication mediated by connexins is crucial to various cellular functions, including the regulati...
متن کاملLife cycle of connexins in health and disease.
Evaluation of the human genome suggests that all members of the connexin family of gap-junction proteins have now been successfully identified. This large and diverse family of proteins facilitates a number of vital cellular functions coupled with their roles, which range from the intercellular propagation of electrical signals to the selective intercellular passage of small regulatory molecule...
متن کاملConnexins in the Nervous System
This chapter reviews the localizations and physiological roles of connexins in neurons and glia of the central and peripheral nervous systems. Cx32 forms gap junctions in noncompact myelin in Schwann cells, which are thought to form a reflexive communication pathway connecting the outer and inner myelin layers. Cx29 is also expressed in myelinating Schwann cells, but does not appear to form gap...
متن کاملConnexins in leukocytes: shuttling messages?
Gap junctions, formed by the connexin (Cx) protein family, are intercellular channels that permit the cytoplasmic exchange of ions and small metabolites between neighboring cells, a process called gap junction intercellular communication (GJIC). These channels possess unique properties, including distinctive permeabilities for various signaling molecules, which depend on the connexin member(s) ...
متن کاملWhich connexins connect?
Electrical signaling via gap junctions modulates vascular function via 2 physiologically interrelated mechanisms, namely dilations/constrictions that propagate longitudinally along the vessel wall,1–4 and the EDHF phenomenon, in which relaxation is facilitated by the transmission of endothelial hyperpolarization to smooth muscle via a radial myoendothelial pathway.5 Gap junctions are composed f...
