Gap junctions are intercellular channels that allow small molecules and electrical current to passively diffuse between adjacent cells. They are found in neurons and glia throughout the nervous system ...

Tight junctions (blue dots) between cells are connected areas of the plasma membrane that stitch cells together. Adherens junctions (red dots) join the actin filaments of neighboring cells together.

Proceedings of the National Academy of Sciences of the United States of America, Vol. 98, No. 7 (Mar. 27, 2001), pp. 4190-4195 (6 pages) Gap junctional communication between microglia was investigated ...

The same kind of neurons can have completely different wiring diagrams in the rat and mouse, as mice lack intercellular molecular channels known as gap junctions, researchers at Karolinska Institutet ...

Rat heart and other organs contain mRNA coding for connexin43, a polypeptide homologous to a gap junction protein from liver (connexin32). To provide direct evidence that connexin43 is a cardiac gap ...
