Gap junctions are specialised intercellular channels that facilitate direct communication between adjacent cells by allowing the regulated exchange of ions, second messengers and small metabolites.

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 ...

Gap junctions contain numerous channels that are clustered in apposed membrane patches of adjacent cells. These cell-to-cell channels are formed by pairing of two hemichannels or connexons, and are ...

Scientists have uncovered a key role for the protein “Frazzled” in building and maintaining the rapid neural connections that allow fruit flies to react in milliseconds.

Ischemia reperfusion injury (IRI) is one of the main cause of organ dysfunction after heart attack and solid organ transplantation, and occurs frequently when the new organ comes from a deceased ...

There is a lot of excitement in the field of cell to cell communications. From the well known Gap junctions (small channels between cells) to the lesser known desmosomes (anchor points of contact ...

Anchored Protein Kinase-A (PKA) bound to A-Kinase Anchoring Protein (AKAP) mediates the effects of localized increases in cAMP in defined subcellular microdomains and retains the specificity in ...

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 ...

Researchers studying a critical stage of pregnancy – implantation of the embryo in the uterus – have found a protein that is vital to the growth of new blood vessels that sustain the embryo. Without ...

A new study by the University of California, Davis, shows how cells work together to avoid a sudden drop in blood sugar. Understanding these feedback loops could improve the lives of people with ...

Adeno-associated virus vector containing an adenine base editor provides an effective strategy to treat hereditary hearing loss caused by the R75W mutation. Moreover, this gene editing technology can ...
