Overview
Gap junctions are crucial structures that facilitate direct communication between adjacent cells, allowing for the transfer of ions and small molecules. They are composed of connexins, which form channels that enable rapid signaling, essential for coordinating functions in tissues such as the heart ...
Key Terms
Example: Different types of connexins can create gap junctions with varying permeability.
Example: Hormones and neurotransmitters are common signaling molecules.
Example: Gap junctions help maintain tissue homeostasis in the heart.
Example: Cardiac muscle cells are electrically coupled to ensure synchronized contractions.
Example: Gap junction dysfunction can lead to pathological conditions.
Example: Research on gap junctions may enhance regenerative therapies.
