INTEGRINS: A BEDSIDE TO BENCH TO BEDSIDE STORY
1Boston, Massachusetts.
I provide a narrative of the path I took to discover the membrane receptors that mediate leukocyte adhesion, now known as β2 integrins or CD11/CD18. We followed this discovery with the first determination of the 3-D structures of integrins. The latter advance provided the foundation for understanding the unique features of integrins as divalent cation-dependent signaling receptors and as mechanosensitive conduits between the extracellular matrix and the intracellular cytoskeleton. Our structural studies are now opening new paths for taming overactive integrins in disease while minimizing the collateral damage associated with the faulty pharmacodynamics of current integrin inhibitory drugs.
