Dr. Glorioso has spent his career studying the molecular biology of HSV and the last 20 years developing HSV gene vectors. He is a world-wide leader in this field and has to the expertise to develop the technology related to the treatment of diseases of the peripheral and central nervous system. His interest in peripheral nerve disease has included nerve degeneration due to diabetes and cancer drug therapies that have led to treatments of animal models. Studies to understand the pathophysiology of chronic pain and the identification of gene therapy interventions that create effective pain therapies have been long standing interests and he was among the first to develop HSV vectors to treat pain. This research has culminated in clinical trials for treatment of cancer pain. Dr. Glorioso has also focused his attention on neurodegenerative diseases that include SCA1 and Huntington's disease and the development of oncolytic vectors to treat brain tumors. Part of this research extends his application of HSV vectors for vector delivery across the blood brain barrier and for targeting specific neuronal cell populations in animals. He has also recently developed HSV vectors for the creation and neuronal differentiation of human iPS cells derived from fetal brain and human fibroblasts.
Research in the Barratt-Boyes laboratory addresses the immunology of infectious diseases of importance to humans.
Research in my lab combines nuclear magnetic resonance (NMR) spectroscopy with biophysics, biochemistry, and chemistry to investigate cellular processes at the molecular and atomic levels in relation to human disease. We presently focus on two areas in biology: gene regulation and HIV pathogenesis. To understand how biological macromolecules work and intervene with respect to activity and function, detailed knowledge of their architecture and dynamic features is required. Evaluation of the major determinants for stability and conformational specificity of normal and disease-causing forms of these molecules will allow us to unravel the complex processes associated with disease. Our group has developed new NMR methods for determining three-dimensional structures of biological macromolecules and applies these to challenging systems. Key contributions include the development of restrained molecular dynamics/simulated annealing algorithms and multidimensional, heteronuclear spectroscopy, which allowed the extension of conventional NMR methods to higher molecular weight systems. Our group has solved solution structures of a large number of medically and biologically important proteins, including cytokines and chemokines, transcription factors and their complexes and various HIV and AIDS related proteins. Work is also carried out on protein folding and design using the model protein GB1.
