Dr. Wiley's research concentrates on the pathogenesis of neurodegenerative diseases and in particular on viral and age induced nervous system diseases. Viruses damage the nervous system either by direct infection of neural cells or by secondary effects of an immune response. In recent years his studies have focused on central nervous system retroviral infections and have pioneered the use of molecular and imaging techniques to quantitatively assess viral burden. This same technology is now being applied to quantify neurological damage and the immune / neuroinflammatory response with specific attention focused on disruption of the extracellular matrix and how this leads to synaptic damage. Using MRI and PET he is investigating the evolution of blood brain barrier defects and macrophage trafficking in mediating neurological disease. Trainees in Dr. Wiley's laboratory have the opportunity to learn a wide variety of techniques related to studying degeneration of the nervous system. Whole organism techniques include; PET, MRI, brain harvesting and sampling, and small animal perfusion, histological techniques include; immunocytochemistry, in situ hybridization and ultrastructural analysis. Training on laser confocal and electron microscopes is available. Protein techniques include; antibody purification and tagging. Molecular techniques include; RNA and DNA extraction from tissues, competitive PCR probe construction and quantitation. Lab rotation projects involve quantitation of mRNA and protein expression in human nervous system tissue in vivo or in vitro.
