Adjacent cells freely exchange small molecules and ions with each other through channels made from proteins called connexins. Dysfunction in this important type of intercellular communication has ...

Gap junctions (yellow) are clusters of channels that form tunnels of aqueous connectivity between cells.

local activation of fluorescent molecular probes (LAMP), which uses the cell-permeable caged dye NPE-HCCC2/AM to study cell gap junction coupling 1. To extend this assay to cells in physiological ...
