Developmental shift to a mechanism of synaptic vesicle endocytosis requiring nanodomain Ca2+

T Yamashita, K Eguchi, N Saitoh, H von Gersdorff… - Nature …, 2010 - nature.com
Ca 2+ is thought to be essential for the exocytosis and endocytosis of synaptic vesicles.
However, the manner in which Ca 2+ coordinates these processes remains unclear, particularly …

Wild-type monomeric α-synuclein can impair vesicle endocytosis and synaptic fidelity via tubulin polymerization at the calyx of held

K Eguchi, Z Taoufiq, O Thorn-Seshold… - Journal of …, 2017 - Soc Neuroscience
α-Synuclein is a presynaptic protein the function of which has yet to be identified, but its
neuronal content increases in patients of synucleinopathies including Parkinson's disease. …

[HTML][HTML] Frequency-dependent block of excitatory neurotransmission by isoflurane via dual presynaptic mechanisms

HY Wang, K Eguchi, T Yamashita… - Journal of …, 2020 - Soc Neuroscience
Volatile anesthetics are widely used for surgery, but neuronal mechanisms of anesthesia
remain unidentified. At the calyx of Held in brainstem slices from rats of either sex, isoflurane at …

[HTML][HTML] Advantages of acute brain slices prepared at physiological temperature in the characterization of synaptic functions

K Eguchi, P Velicky, E Hollergschwandtner… - Frontiers in Cellular …, 2020 - frontiersin.org
Acute brain slice preparation is a powerful experimental model for investigating the
characteristics of synaptic function in the brain. Although brain tissue is usually cut at ice-cold …

Microtubule assembly by tau impairs endocytosis and neurotransmission via dynamin sequestration in Alzheimer's disease synapse model

T Hori, K Eguchi, HY Wang, T Miyasaka, L Guillaud… - Elife, 2022 - elifesciences.org
Elevation of soluble wild-type (WT) tau occurs in synaptic compartments in Alzheimer’s disease.
We addressed whether tau elevation affects synaptic transmission at the calyx of Held in …

[PDF][PDF] Maturation of a PKG-dependent retrograde mechanism for exoendocytic coupling of synaptic vesicles

K Eguchi, S Nakanishi, H Takagi, Z Taoufiq… - Neuron, 2012 - cell.com
At presynaptic terminals vesicular membranes are fused into plasma membrane upon
exocytosis and retrieved by endocytosis. During a sustained high-frequency transmission, …

Microtubule and actin differentially regulate synaptic vesicle cycling to maintain high-frequency neurotransmission

LPA Babu, HY Wang, K Eguchi, L Guillaud… - Journal of …, 2020 - Soc Neuroscience
Cytoskeletal filaments such as microtubules (MTs) and filamentous actin (F-actin) dynamically
support cell structure and functions. In central presynaptic terminals, F-actin is expressed …

[HTML][HTML] The number and distinct clustering patterns of voltage-gated calcium channels in nerve terminals

K Eguchi, J Montanaro, E Le Monnier… - Frontiers in …, 2022 - frontiersin.org
Upon the arrival of action potentials at nerve terminals, neurotransmitters are released from
synaptic vesicles (SVs) by exocytosis. Ca V 2.1, 2.2, and 2.3 are the major subunits of the …

Rho-kinase accelerates synaptic vesicle endocytosis by linking cyclic GMP-dependent protein kinase activity to phosphatidylinositol-4, 5-bisphosphate synthesis

Z Taoufiq, K Eguchi, T Takahashi - Journal of Neuroscience, 2013 - Soc Neuroscience
Rho-kinase plays diverse roles in cell motility. During neuronal development, Rho-kinase is
involved in neuronal migration, and in neurite outgrowth and retraction. Rho-kinase remains …

Vesicular glutamate filling and AMPA receptor occupancy at the calyx of Held synapse of immature rats

T Yamashita, T Kanda, K Eguchi… - The Journal of …, 2009 - Wiley Online Library
At central glutamatergic synapses, neurotransmitter often saturates postsynaptic AMPA
receptors (AMPARs), thereby restricting the dynamic range of synaptic efficacy. Here, using …
