Targeted Sensors for Glutamatergic Neurotransmission [PDF]
Biophysical Journal, 2021 AbstractOptical report of neurotransmitter release allows visualization of excitatory synaptic transmission. Sensitive genetically-encoded glutamate reporters operating with a range of affinities and emission wavelengths are available. However, without targeting to synapses, the specificity of the fluorescent signal is uncertain, compared to sensors ...

Paired associative stimulation demonstrates alterations in motor cortical synaptic plasticity in patients with hepatic encephalopathy [PDF]
Clinical Neurophysiology, Volume 132, Issue 10, October 2021,
Pages 2332-2341, 2022 Objective: Hepatic encephalopathy (HE) is a potentially reversible brain dysfunction caused by liver failure. Altered synaptic plasticity is supposed to play a major role in the pathophysiology of HE. Here, we used paired associative stimulation with an inter-stimulus interval of 25 ms (PAS25), a transcranial magnetic stimulation (TMS) protocol, to ...

Phosphatidic acid and neurotransmission [PDF]
Advances in Biological Regulation, 2017 Lipids play a vital role in the health and functioning of neurons and interest in the physiological role of neuronal lipids is certainly increasing. One neuronal function in which neuronal lipids appears to play key roles in neurotransmission. Our understanding of the role of lipids in the synaptic vesicle cycle and neurotransmitter release is becoming

Long-term memory and synapse-like dynamics in two-dimensional nanofluidic channels [PDF]
Science 379, 161-167 (2023), 2022 Fine-tuned ion transport across nanoscale pores is key to many biological processes such as neurotransmission. Recent advances have enabled the confinement of water and ions to two dimensions, unveiling transport properties unreachable at larger scales and triggering hopes to reproduce the ionic machinery of biological systems.

Dopamine drives Drosophila sechellia adaptation to its toxic host
eLife, 2014 Many insect species are host-obligate specialists. The evolutionary mechanism driving the adaptation of a species to a toxic host is, however, intriguing.

Risperidone response in patients with schizophrenia drives DNA methylation changes in immune and neuronal systems [PDF]
, 2023 Background: The choice of efficient antipsychotic therapy for schizophrenia relies on a time-consuming trial-and-error approach, whereas the social and economic burdens of the disease call for faster alternatives. Material \& methods: In a search for predictive biomarkers of antipsychotic response, blood methylomes of 28 patients were analyzed before ...

Optical Modulation of Neurotransmission [PDF]
Biophysical Journal, 2013 The computational properties of an isolated neuron have been analyzed in detail by postsynaptic activation with caged compounds. However, new tools are needed to manipulate neurotransmission at individual synapses in order to understand how a neuron integrates physiological stimuli received from presynaptic neurons within a circuit.
