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.

Researchers at The Hong Kong University of Science and Technology (HKUST) have developed CarGAP, a chemo-optogenetic tool that uses vitamin B₁₂ and green light to precisely control gap junctions, the ...

Epithelial tissues are in constant interaction with their environment. Maintaining their functionality requires dynamic balance (homeostasis) and that their cell numbers are tightly regulated. This is ...
