Integrin activation

Integrin activation is a process by which certain proteins on cell surfaces change shape to become more effective at connecting cells to their surroundings or to each other. Normally, integrins are in a less active state, but when signals or specific signals are received, they undergo structural changes that increase their ability to bind to other molecules, such as the extracellular matrix or neighboring cells. This activation helps cells adhere, move, or communicate, which is essential for processes like wound healing, immune response, and tissue maintenance.
