Integrins are a family of cell surface receptors that play a crucial role in cell adhesion, migration, and signal transduction. They are composed of two subunits, alpha and beta, which combine to form different receptor complexes that bind to specific extracellular matrix proteins. Integrins are involved in various physiological processes, such as embryonic development, immune response, and wound healing, as well as in pathological conditions, including cancer and inflammatory diseases. Research in the field of integrin biology focuses on understanding the structure, function, and regulation of integrins, as well as their potential as therapeutic targets for treating various diseases.
