 Project objective

Synaptic transmission is an extremely energetically-demanding process that consumes 75% of the energy required for brain function. However, it remains poorly understood how synapses guarantee the necessary ATP levels required for neurotransmission. While our understanding of the metabolic pathways for ATP production is vastly detailed, very little is known about the actual molecular implementation of these pathways in neurons for sustaining synaptic bioenergetics. I hypothesize that tightly-regulated control mechanisms exist presynaptically to ensure the molecular activation of glycolysis and oxidative phosphorylation (OxPhos) on demand, optimally coupling local ATP synthesis to consumption thereby maintaining synaptic metabolic integrity and safeguarding presynaptic function. Here I propose to develop a comprehensive molecular understanding of the mechanisms controlling these pathways in firing synapses. I will use cutting-edge optophysiology tools that I and others have developed to study neuronal bioenergetics together with novel proteomic approaches to identify key molecules involved in controlling presynaptic OxPhos and glycolysis. First, I will dissect the fundamental mechanisms controlling Ca2-mediated activation of OxPhos in presynaptic mitochondria during synaptic activity. To further elucidate the presynaptic choreography of molecular mechanisms enhancing glycolysis rates on demand, I will dissect the mechanistic control of the presynaptic glucose carrier GLUT4 and establish the role of glycolytic metabolons in accelerating glycolysis during synaptic activity. By generating for the first time a comprehensive picture of the molecular mechanisms actively maintaining presynaptic metabolic integrity, this study will provide a framework for future studies into the molecular basis of brain disease states associated with dysfunctional metabolism, such as mitochondriopathies, vascular dementias or glucose metabolism diseases.

Are you the coordinator (or a participant) of this project? Plaese send me more information about the "SYNAPTOENERGY" project.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an  email (fabio@fabiodisconzi.com) and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.
