Gap junctions are membrane channels between adjacent cells that allow the direct exchange of cytoplasmic substances. [1] Substances exchanged include small molecules, substrates, and metabolites. [1]

2019年10月4日 · Gap junctions are a type of cell junction in which adjacent cells are connected through protein channels. These channels connect the cytoplasm of each cell and allow molecules, ions, and electrical signals to pass between them.

2023年8月29日 · Gap junctions allow direct communication between neighboring cells. It allows them to exchange various substances, including ions, metabolites, and signaling molecules. This direct transfer of substances facilitates coordinated …

Gap junctions are aggregates of intercellular channels that permit direct cell–cell transfer of ions and small molecules. Initially described as low-resistance ion pathways joining excitable cells (nerve and muscle), gap junctions are found joining ...

2022年12月30日 · Unlike the other types of cell-cell adhesion, the gap junction (sometimes called a nexus) connects not only the outside of two cells, it connects their cytoplasm as well. Each cell has a connexon (aka hemichannel) made of six connexin proteins.

2023年1月17日 · Gap junctions allow various molecules and ions to pass freely between cells. A gap junction channel is composed of two connexons, also known as hemichannels that line up across the intercellular space.

2025年1月6日 · Cell - Gap Junctions, Intercellular Communication, Connexins: These junctions allow communication between adjacent cells via the passage of small molecules directly from the cytoplasm of one cell to that of another.

Gap junctions are essential to the function of multicellular animals, which require a high degree of coordination between cells. In vertebrates, gap junctions comprise connexins and currently 21 connexins are known in humans. The functions of gap ...

2021年1月19日 · A gap junction is a type of cell junction characterized by an intercellular bridge (i.e. ~2 nm gap) that forms between the membranes of neighboring cells. It is involved in intercellular communication, i.e. allowing the direct passage of ions, small molecules, or electrical impulses from one cell to another.

2024年1月13日 · Gap junctions are collections of intercellular channels that allow ions and tiny molecules to move directly between cells. Gap junctions are found connecting nearly all cells in solid tissues and were first identified as low-resistance ion channels interconnecting excitable cells (nerve and muscle).
