Acute genetic manipulation of neuronal activity for the functional dissection of neural circuits-a dream come true for the pioneers of behavioral geneticsMoto Yoshihara
Department of Neurobiology, University of Massachusetts Medical School, Worcester, Massachusetts 01605 4321, USA
J Neurogenet 26:43-52. 2012..This methodology opened a new avenue to dissect functions of neural circuits to make dreams of the pioneers into reality...
Differential regulation of synchronous versus asynchronous neurotransmitter release by the C2 domains of synaptotagmin 1Motojiro Yoshihara
Picower Institute for Learning and Memory, Department of Biology, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Proc Natl Acad Sci U S A 107:14869-74. 2010..These results suggest that the tandem C2 domains of Syt 1 play independent roles in neurotransmission, as Ca(2+) binding to C2A suppresses asynchronous release, whereas Ca(2+) binding to C2B mediates synchronous fusion...
Synaptotagmins are trafficked to distinct subcellular domains including the postsynaptic compartmentBill Adolfsen
The Picower Center for Learning and Memory, Department of Biology, Massachusetts Institute of Technology, Cambridge 02139, USA
J Cell Biol 166:249-60. 2004..In addition, the identification of a postsynaptic synaptotagmin suggests calcium-dependent membrane-trafficking functions on both sides of the synapse...
Retrograde signaling by Syt 4 induces presynaptic release and synapse-specific growthMotojiro Yoshihara
Picower Institute for Learning and Memory, Department of Biology, Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Science 310:858-63. 2005..Postsynaptic Ca2+ influx also stimulates local synaptic differentiation and growth through Syt 4-mediated retrograde signals in a synapse-specific manner...
The synaptotagmins: calcium sensors for vesicular traffickingMotojiro Yoshihara
The Picower Center for Learning and Memory, Department of Biology, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Neuroscientist 10:566-74. 2004..This suggests an intriguing possibility that syt 4 may mediate a postsynaptic vesicle trafficking pathway, providing a molecular basis for an evolutionarily conserved bidirectional vesicular trafficking communication system at synapses...
Synaptotagmin I functions as a calcium sensor to synchronize neurotransmitter releaseMotojiro Yoshihara
Picower Center for Learning and Memory, Cambridge, MA, USA
Neuron 36:897-908. 2002..These results indicate that synaptotagmin is the major Ca(2+) sensor for evoked release and functions to trigger synchronous fusion in response to Ca(2+), while suppressing asynchronous release...
Presynaptic N-type calcium channels regulate synaptic growthGabrielle E Rieckhof
Department of Biology, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA
J Biol Chem 278:41099-108. 2003..Linking presynaptic voltage-gated calcium entry to downstream calcium-sensitive synaptic growth regulators provides an efficient activity-dependent mechanism for modifying synaptic strength...
Cytoplasmic aggregates trap polyglutamine-containing proteins and block axonal transport in a Drosophila model of Huntington's diseaseWyan Ching Mimi Lee
Picower Center for Learning and Memory, Department of Biology, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Proc Natl Acad Sci U S A 101:3224-9. 2004..Our findings indicate that nonnuclear events induced by cytoplasmic huntingtin aggregation play a central role in the progressive neurodegeneration observed in Huntington's disease...
Is synaptotagmin the calcium sensor?Motojiro Yoshihara
Picower Center for Learning and Memory and Department of Biology, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Curr Opin Neurobiol 13:315-23. 2003..Biochemical and genetic studies suggest that lipid and SNARE interactions underlie synaptotagmin's ability to mediate the incredible speed of vesicle fusion that is the hallmark of fast synaptic transmission...
