Gap junctional communication is a widespread mechanism for metabolic coupling of adjoining cells. In the immune system, evidence has built up showing that lymphocytes possess the protein building blocks of gap junctions, the connexins. The most widespread is connexin 43, but connexin 40 is also present in secondary lymphoid organs. Inhibitors of gap junctional communication, especially the high...
Both neurons and glia throughout the central nervous system are organized into networks by gap junctions. Among glia, gap junctions facilitate metabolic homeostasis and intercellular communication. Among neurons, gap junctions form electrical synapses that function primarily for communication. However, in neurodegenerative states due to disease or injury gap junctions may be detrimental to surv...
PURPOSE This study is designed to provide a comprehensive expression profile of connexins in the human corneal epithelium (in vivo) and in cultured primary corneal epithelial cells (PCECs) (in vitro). It also evaluates the pathologic effects of a pathogenic missense mutation in Cx26, which causes keratitis-ichthyosis-deafness syndrome (KIDS), a rare genetic disorder with corneal involvement. ...
Gap junctions are intercellular channels made of connexin proteins, mediating both electrical and biochemical signals between cells. The ability of gap junction proteins to regulate immune responses, cell proliferation, migration, apoptosis and carcinogenesis makes them attractive therapeutic targets for treating inflammatory and neoplastic disorders in different organ systems. Alterations in g...
PURPOSE Within the corneal stroma, keratocytes communicate through gap junctions. These plasma membrane channels, which connect the cytoplasm of adjacent cells, are composed of connexins. In a cell culture model, an investigation was conducted to determine whether connexin-based gap junction intercellular communication is present in fibroblasts and myofibroblasts, both of which replace keratocy...
Electrophysiological properties of gap junction channels and mechanisms involved in the propagation of intercellular calcium waves were studied in cultured spinal cord astrocytes from sibling wild-type (WT) and connexin43 (Cx43) knock-out (KO) mice. Comparison of the strength of coupling between pairs of WT and Cx43 KO spinal cord astrocytes indicates that two-thirds of total coupling is attrib...
