    Collapse Overview
    The Sieburth lab studies synaptic signaling pathways that regulate synaptic function, with the goal of understanding how these pathways contribute to the function of neuronal circuits controlling behavioral programs in the nervous system. My laboratory uses C. elegans as a model organism for studying synaptic biology, because of its simple neuronal circuitry, the ability to visualize synapses by fluorescent imaging in live animals, and its powerful genetics. We combine state of-the-art behavioral, genetic, cell biological, and in vivo neuronal imaging techniques in to study the cellular molecular mechanisms underlying secretion of synaptic vesicles and dense core vesicles. My lab is interested in three major areas: 1) How does localized sphingolipid signaling at presynaptic terminals regulate synaptic transmission at neuromuscular junctions, 2) The mechanisms by which oxidative stress regulates synaptic transmission and behavior, and 3) How does a neuropeptide signaling pathway deliver timing information from a pacemaker to activate a rhythmic behavioral circuit.
