TLR2 Regulates Gap Junction Intercellular Communication in Airway Cells

Communication in Airway Cells TLR2 Regulates Gap Junction Intercellular

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...

Reduction 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...

Extracellular 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...
