Assembly of gap junction intercellular communication channels.
788 with a lipidlprotein molar ratio of 100:1, a value close to that found in most biological membranes [21]. The data show that the calculation of distances between sites within the monomer of a membrane protein of a cross-sectional diameter of 5 nm based only from FET efficiency measurements is largely speculative in most cases in native biological membranes. Because the contribution of FET t...
متن کاملGap junction-mediated intercellular communication in the immune system.
Immune cells are usually considered non-attached blood cells, which would exclude the formation of gap junctions. This is a misconception since many immune cells express connexin 43 (Cx43) and other connexins and are often residing in tissue. The role of gap junctions is largely ignored by immunologists as is the immune system in the field of gap junction research. Here, the current knowledge o...
متن کاملUltraviolet A exposure induces reversible disruption of gap junction intercellular communication in lens epithelial cells.
Gap junction intercellular communication (GJIC) is essential for the proper function of many organs including the lens. Disruption of GJIC can cause lens metabolic disorder and can induce cataracts. The purpose of this study was to investigate the signal transduction pathways involved in GJIC disruption following ultraviolet A (UVA) exposure in lens epithelial cells. Following exposure of human...
متن کاملReduction in gap junction intercellular communication promotes glioma migration
Glioblastoma Multiforme (GBM), an aggressive form of adult brain tumor, is difficult to treat due to its invasive nature. One of the molecular changes observed in GBM is a decrease in the expression of the gap junction protein Connexin43 (Cx43); however, how a reduction in Cx43 expression contributes to glioma malignancy is still unclear. In this study we examine whether a decrease in Cx43 prot...
متن کاملExtracellular currents alter gap junction intercellular communication in synovial fibroblasts.
We studied the effect of extremely low frequency (ELF) currents on gap junction intercellular communication (GJIC) mediated by connexin43 protein. Confluent monolayers of synovial fibroblasts (HIG-82) and neuroblastoma cells (5Y) were exposed in bath solution to 0-75 mA/m(2) (0-56 mV/m), 60 Hz. Single channel conductance, cell membrane current-voltage (I-V) curves, and Ca(2+) influx were measur...
