Extrasynaptic Communication

open access: yesFrontiers in Molecular Neuroscience, 2021
Streams of action potentials or long depolarizations evoke a massive exocytosis of transmitters and peptides from the surface of dendrites, axons and cell bodies of different neuron types.

Acetylcholine as a trigger of the somatic exocytosis in Retzius neurons [PDF]

open access: yes, 2020
Abstract The redistribution of vesicles containing serotonin in leech neurons was studied using the fluorescent, scanning ion-conductance, and laser phase microscopy methods. During acetylcholine receptor (AChR) activation in Retzius neurons, the changes of Ca 2+ desorption ...

Modulation of synaptic vesicle exocytosis in muscle-dependent long-term depression at the amphibian neuromuscular junction. [PDF]

open access: yesPLoS ONE, 2014
We have labeled recycling synaptic vesicles at the somatic Bufo marinus neuromuscular junction with the styryl dye FM2-10 and provide direct evidence for refractoriness of exocytosis associated with a muscle activity-dependent form of long-term ...

Biophysics of active vesicle transport, an intermediate step that couples excitation and exocytosis of serotonin in the neuronal soma. [PDF]

open access: yesPLoS ONE, 2012
Transmitter exocytosis from the neuronal soma is evoked by brief trains of high frequency electrical activity and continues for several minutes. Here we studied how active vesicle transport towards the plasma membrane contributes to this slow phenomenon ...

Primary neurons lacking the SNAREs vti1a and vti1b show altered neuronal development

open access: yesNeural Development, 2022
Background Neurons are highly specialized cells with a complex morphology generated by various membrane trafficking steps. They contain Golgi outposts in dendrites, which are formed from somatic Golgi tubules.

Exocytosis of serotonin from the neuronal soma is sustained by a serotonin and calcium-dependent feedback loop

open access: yesFrontiers in Cellular Neuroscience, 2014
The soma of many neurons releases large amounts of transmitter molecules through an exocytosis process that continues for hundreds of seconds after the end of the triggering stimulus.

Extrasynaptic exocytosis and its mechanisms: a source of molecules mediating volume transmission in the nervous system

open access: yesFrontiers in Physiology, 2012
We review the evidence of exocytosis from extrasynaptic sites in the soma, dendrites and axonal varicosities of central and peripheral neurons of vertebrates and invertebrates, and how it may contribute to signaling in the nervous system.

Extrasynaptic Neurotransmission Mediated by Exocytosis and Diffusive Release of Transmitter Substances

open access: yesFrontiers in Synaptic Neuroscience, 2018
This review article deals with the mechanisms of extrasynaptic release of transmitter substances, namely the release from the soma, axon and dendrites in the absence of postsynaptic counterparts.

Bilateral lichen striatus: A case report with review of literature

open access: yesIndian Dermatology Online Journal, 2017
Lichen striatus is a self-limiting dermatosis presenting with sudden eruption of lichenoid papules along the lines of Blaschko. A 5-year-old girl presented with asymptomatic hypopigmented linear lesions over both upper limbs.

Capacitance measurement of dendritic exocytosis in an electrically coupled inhibitory retinal interneuron: an experimental and computational study

open access: yesPhysiological Reports, 2019
Exocytotic release of neurotransmitter can be quantified by electrophysiological recording from postsynaptic neurons. Alternatively, fusion of synaptic vesicles with the cell membrane can be measured as increased capacitance by recording directly from a ...
