Physical Chemistry of the Synapse
The focus of this lab is the study of the molecular basis of synaptic transmission in the mammalian brain. Our primary interests lie in understanding the molecular basis of synaptic performance.
We use biophysical tools to examine synapse function. These tools provide single synapse measurements of exocytosis, endocytosis, action potential wave forms, calcium fluxes as well as the concentration of key metabolites. The brain is acutely sensitive to metabolic compromise. We showed recently that nerve terminals represent one of the key loci of this vulnerability (Cell 2014, Neuron 2020, Science Advances 2021). These studies opened up several key questions the Ryan lab is currently pursuing about synaptic metabolism. How much ATP do different processes at synapses consume? What are the biochemical rules in play to synthesize ATP in response to activity? What are the biochemical reasons synapses are so vulnerable? Do neurodegenerative diseases impact synaptic bioenergetics?
