Neuronal survival and development.
Modification of synaptic neurotransmission at glutamatergic synapses and activation of Ca2+-dependent second messenger systems contribute to the processes of learning and memory, neuronal survival and differentiation. In addition, these systems play important roles in the neuronal dysfunction that is observed following stroke and ischemia, focal epilepsies and Alzheimer’s disease. Our research program is focused on analysis of the expression and functional responsiveness of distinct excitatory amino acid receptors (NMDA subtypes), modulation of responses by Ca+2-dependent protein kinases, and examination of the roles of these receptors and kinases in neuronal survival and differentiation. Dissociated neuronal cultures and knockout mice are used as model systems.
