Arnaout Laboratory

A primary research goal of the Arnaout Laboratory is to elucidate the structure and function of integrins, cell adhesion receptors that play vital roles in normal physiology and disease. Other research interests include regulation of the diameter of blood vessels and renal tubules, fate determination in hemangioblasts, precursors of the vascular and blood cell compartments, microfluidic devices for dialysis and structure-based drug design.

A major research focus of the Arnaout Laboratory is dissecting the role of integrins in health and disease. Integrins play pivotal roles in mediating homing of leukocytes and platelets to sites of injury, thus fending off pathogens and maintaining hemostasis, respectively. Integrins are normally expressed on the cell surface in an inactive conformation, but rapidly switch into the active ligand-binding state by agonists. Ligands bind activated integrins eliciting classic outside-in signals that regulate every aspect of cell function. Improper activation of integrins is associated with common diseases including atherosclerosis, thrombosis, diabetes, and cancer. Using genetic, molecular and structural biology approaches, our goal is to define the structural basis of affinity regulation in integrins, elucidate the intracellular pathways that regulate these receptors and that mediate their downstream effects, and use this information in designing structure-based novel therapeutics to treat common diseases linked to integrin dysfunction.
