GABAA receptors and neuroligin 2 synergize to promote synaptic adhesion and inhibitory synaptogenesis

open access: yesFrontiers in Cellular Neuroscience
GABAA receptors (γ-aminobutyric acid-gated receptors type A; GABAARs), the major structural and functional postsynaptic components of inhibitory synapses in the mammalian brain, belong to a family of GABA-gated Cl−/HCO3− ion channels.

Spatiotemporal Drug Delivery via a Neonatal Spinal Cord ECM Hydrogel for Biomimetic Microenvironment Remodeling After Spinal Cord Injury

open access: yesAdvanced Functional Materials, EarlyView.
A biomimetic hydrogel derived from neonatal spinal cord ECM (DNSCM) delivers LAMB2 protein and ISP peptide to remodel the inhibitory injury microenvironment. The system sustains drug release, upregulates pro‐regenerative LAMB2, downregulates inhibitory CSPG, and promotes axonal regeneration.

The P2X receptor mediated regulation of inhibitory synaptic transmission [PDF]

open access: yes
In the central nervous system ATP can be released by neurons and glial cells through similar pathways as other neurotransmitters. Extracellular ATP targets P2X purinoreceptors, causing an influx of Ca2+ ions which transmit very important messages for ...

A53T-alpha-synuclein overexpression impairs dopamine signaling and striatal synaptic plasticity in old mice

open access: yes, 2010
BACKGROUND: Parkinson's disease (PD), the second most frequent neurodegenerative disorder at old age, can be caused by elevated expression or the A53T missense mutation of the presynaptic protein alpha-synuclein (SNCA). PD is characterized pathologically

Mechanoluminescent HOF Nanotransducers Enabled Sono‐Optogenetics in Parkinsonian Rats

open access: yesAdvanced Functional Materials, EarlyView.
We present a mechanoluminescent system utilizing porous hydrogen‐bonded organic frameworks (HOFs) as a toolkit for focused ultrasound‐triggered, non‐invasive light delivery to the deep brain in rats. This approach enables the specific activation of PV‐GPe neurons in dopamine‐depleted Parkinson's disease rat models, resulting in a comparable alleviation

Glutamate transporters are involved in direct inhibitory synaptic transmission in the vertebrate retina

open access: yesOpen Biology
In the central nervous system of vertebrates, glutamate serves as the primary excitatory neurotransmitter. However, in the retina, glutamate released from photoreceptors causes hyperpolarization in post-synaptic ON-bipolar cells through a glutamate-gated

Electro‐Steric Ion Confinement in Polyelectrolyte Networks for Robust Nonvolatile Artificial Synapse

open access: yesAdvanced Functional Materials, EarlyView.
Polyelectrolyte stoichiometry governs ion transport and retention in electrolyte‐gated synaptic transistors. A PSS‐rich network creates electro‐steric ion confinement that suppresses ion back‐diffusion and stabilizes channel doping, enabling robust nonvolatile synaptic memory, linear weight updates, and low‐energy operation.

Spinal Microglial TLR7 Activation Drives Hyperalgesia in a Lupus Mouse Model via Upregulation of IL-1β, IL-18, and Cav2.2 and Enhanced Glutamatergic Synaptic Activity

open access: yesCells
Patients with systemic lupus erythematosus (SLE) often suffer from chronic pain due to a lack of effective and safe analgesics. In this study, we investigated the role of spinal TLR7 in the pathogenesis of chronic pain using female MRL lupus prone (MRL ...

Solution‐Processed Thin‐Film Transistors With Tunable Temporal Dynamics for Neuromorphic Computing

open access: yesAdvanced Functional Materials, EarlyView.
Solution‐processed CNT and CNT/P3HT ion‐gated transistors exhibit materials‐defined synaptic timescales: fast CNT devices for high‐frequency spiking and slow hybrid devices for temporal integration. Embedding these dynamics into coupled reservoir‐computing and spiking neural network simulations reveals that a Hybrid‐Reservoir / CNT‐SNN architecture ...
