Integrins

Integrins are specialized proteins found on the surface of cells that act like sensors and anchors. They help cells attach to their surroundings, such as other cells or the extracellular matrix (a supportive network outside cells). By doing so, integrins transmit signals that influence cell behavior, like movement, growth, or immune responses. They are essential for various biological processes, including wound healing, immune defense, and tissue development. Essentially, integrins serve as communication links, allowing cells to sense their environment and respond appropriately.
