Regular biography
Troy Littleton is a Fellow in the Department of Biology at the Massachusetts Institute of Technology. His research focuses on the formation and function of neuronal connections, as well as how neurological diseases disrupt synaptic communication. Using Drosophila as a model system, he investigates synaptic transmission, learning, memory, and the molecular mechanisms underlying neurological disorders such as epilepsy, autism, and Huntington’s Disease. His work bridges molecular components of the synapse with physiological responses. Littleton's research includes studies on synaptotagmin, complexin, and other proteins involved in neurotransmitter release and synaptic plasticity.
Scholar-generated biography
J. Troy Littleton is a Professor of Neuroscience at MIT, specializing in Synapse Biology. His research explores the molecular mechanisms underlying synaptic transmission, focusing on the role of proteins such as synaptotagmin, complexin, and Rop in neurotransmitter release and synaptic organization. Using Drosophila as a model system, he investigates how calcium-dependent processes regulate synaptic vesicle fusion, exocytosis, and synaptic plasticity. His work also addresses neurodegenerative diseases like Huntington’s disease by examining the impact of polyglutamine aggregates on axonal transport. Through comparative genomics and genetic analysis, he seeks to understand the evolutionary and functional significance of synaptic proteins in both insect and mammalian systems.
