gap junctions

(redirected from neuronal gap junctions)

gap junctions

aligned protein membrane channels of two adjacent cells, allowing passage of low-molecular-weight solutes (ions, chemical messengers, amino acids and glucose) directly between cells

gap junctions

regions of high and special ionic permeability between closely apposed cells. They are places at which cells exchange molecules of large size and provide an avenue by which developing cells can influence each other. Called also nexus.

neuronal gap junctions
very tight contacts between some neurons permitting the almost instant transmission of impulses from one neuron to the other; structural elements extend across the gap conferring a continuity of cytoplasm between the cells.

Neuronal gap junctions may be an unexplored drug target for the treatment of anxiety disorders such as PTSD; they hold promise because giving a regular injection of drugs in a cavity near the abdomen worked as effectively as an injection directly into the brain.
Neuronal gap junctions form where inhibitory neurons touch one another.
Specific topics there include gap junction channel structure, the chemical gating of connexin channels, electrical signaling with neuronal gap junctions, and pharmacology.
