Delta-Notch interaction is a crucial communication process between cells that helps regulate development and cell differentiation. It involves two main components: the Delta ligand, which is a protein found on the surface of one cell, and the Notch receptor, located on an adjacent cell. When Delta binds to Notch, it triggers a signaling cascade that influences the receiving cell's fate, often inhibiting it from becoming a similar type of cell. This interaction is essential in various biological processes, including embryonic development, neurogenesis, and immune response. By controlling how cells communicate and differentiate, Delta-Notch signaling plays a significant role in maintaining proper tissue organization and function.
