Delta Ligand is a type of protein that plays a crucial role in cell signaling, particularly in the development of the nervous system. It is part of the Notch signaling pathway, which helps regulate cell differentiation, proliferation, and apoptosis. Delta Ligand interacts with Notch receptors on adjacent cells, influencing their fate and function. In addition to its role in development, Delta Ligand is also involved in various biological processes, including immune response and tissue regeneration. Dysregulation of Delta Ligand and the Notch pathway can lead to several diseases, including certain types of cancer and developmental disorders.
