Summary of Research Studies: Our research is focused on understanding the mechanisms by which neurotrophic growth factors, including nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF), regulate nervous system development and function. BDNF and NGF have been implicated in the pathophysiology of neurodegenerative disease, neuropsychiatric illness, CNS injury, and obesity. The contributions made by specific neurotrophin-regulated gene products to depression, memory, and energy balance, are being being examined using novel knockout, transgenic, and knockin mouse models. The lab has identified VGF, a secreted peptide precursor and granin family member, and the cell adhesion molecule (CAM) L1 or NILE, as important gene products that are induced by neurotrophin exposure during neural differentiation. Cultured neurons, neural and endocrine cell lines, and hippocampal slices are all utilized to study effects of these proteins on synaptic plasticity, neurogenesis, axonal outgrowth, and axonal pathfinding. Conservation of function of neurotrophin-regulated proteins, including VGF and L1, in simpler vertebrate models such as zebrafish, is also under investigation. We are currently determining the potential functional roles and signaling pathways of these and other neurotrophin-regulated molecules in clinically relevant diseases, including major depression, neuropathic pain, obesity, and fetal alcohol syndrome.
