Function of a gap junction
WebGap junctions are clumps of intercellular channels that allow ions and tiny molecules to flow freely between cells. Gap junctions are low-resistance ion channels that connect excitable cells (nerve and muscle) in solid tissues.Gap-junctional intercellular communication has been adapted to a range of roles and has many regulation mechanisms thanks to its … WebMay 1, 2013 · Gap Junctions. Gap junctions are aggregates of protein channels formed between apposing cells that facilitate intercellular communication by allowing the passage of small molecules and metabolites from one cell to another ().These intercellular channels assemble from connexin (Cx) subunits named after the molecular mass of each family …

WebOct 29, 2024 · A gap junction is a type of protein that helps to connect adjacent cells together. This protein is important for many different functions in the body, including helping to regulate cell communication and cell death. Gap junctions are also involved in the development of some diseases, such as cancer. WebStem cell therapy has emerged as a potential modality for myocardial infarction treatment. Mesenchymal stem cells (MSCs) exert reparative actions in the injured myocardium mainly through the secretion of paracrine factors. In addition, the overexpression of connexin 43 (Cx43), a gap junction protein, promotes cardiac repair and function restoration. It is …
WebCardiac muscle is striated muscle that is present only in the heart. Cardiac muscle fibers have a single nucleus, are branched, and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes to hold the fibers together when the heart contracts.
