Dr. Norman Haughey's research focuses on signaling pathways that promote the dysfunction and death of neuronal cells. In this context, he is interested in the mechanisms that promote neurotoxic processes in HIV and Alzheimer's related dementias. Dr. Haughey and his colleagues use a multidisciplinary approach including tissue culture, molecular reconfiguration, transgenic or knock-out mice and biochemical approaches in order to identify and modify signal transduction pathways that are associated with neurodegenerative processes. Using these model systems, they have described pathogenic modifications of calcium permeable receptors and transporters that promote excessive calcium accumulation. Current research is focused on mapping perturbations in lipid raft based signal transduction pathways that lead to the oxidative modification of subcellular targets involved apoptotic and anti-apoptotic signaling.
A second research interest is in the biology of neural stem and neural progenitor cells. In particular, he is interested in the mechanisms that govern the function and survival of neural stem and neural progenitor cells and how these processes are disrupted in neurodegenerative conditions.
