CRYSTAL STRUCTURE ANALYSIS OF THE COMPLEX LFA-1 (CD11A) I-DOMAIN / LOVASTATIN AT 2.6 A RESOLUTION
Overview
The lymphocyte function-associated antigen (LFA-1) belongs to the family, of beta2-integrins and plays an important role in T-cell activation and, leukocyte migration to sites of inflammation. We report here that, lovastatin, a drug clinically used for lowering cholesterol levels, inhibits the interaction of human LFA-1 with its counter-receptor, intercellular adhesion molecule-1. Using nuclear magnetic resonance, spectroscopy and X-ray crystallography we show that the inhibitor binds to, a highly conserved domain of the LFA-1 alpha-chain called the I-domain., The first three-dimensional structure of an integrin inhibitor bound to, its receptor reveals atomic details for a hitherto unknown mode of LFA-1, inhibition. It also sheds light into possible mechanisms of LFA-1 mediated, signalling and will support the design of novel anti-adhesive and, immunosuppressive drugs.
