Elevated Apolipoprotein E Expression in Hippocampal Microglia Drives Temporal Lobe Epilepsy Progression

Advanced Science, EarlyView.
In temporal lobe epilepsy, hippocampal APOE is markedly upregulated predominantly in microglia. APOE overexpression in microglia drives TLR4 and cGAS/STING‐dependent neuroinflammation, engages bidirectional crosstalk with neurons and astrocytes, increases neuronal excitability, and perturbs hippocampal lipid metabolism. These findings suggest that APOE‐

NDST3‐Induced Epigenetic Reprogramming Reverses Neurodegeneration in Parkinson's Disease

Advanced Science, EarlyView.
NDST3‐mediated epigenetic reprogramming revitalizes neuronal circuits in the substantia nigra and striatum to halt dopaminergic neuron degeneration and restore motor function in Parkinson's disease models. This strategy promotes neuronal maintenance and functional recovery, highlighting NDST3's therapeutic potential in neurodegenerative disorders ...

Postsynaptic protein organization revealed by electron microscopy. [PDF]

, 2019
Neuronal synapses are key devices for transmitting and processing information in the nervous system. Synaptic plasticity, generally regarded as the cellular basis of learning and memory, involves changes of subcellular structures that take place at the ...

Morphine Tolerance Gated through EZH2‐Mediated Suppression of Trpc5 in Spinal GABAergic Interneurons in Male Mice

Advanced Science, EarlyView.
Chronic morphine suppresses Trpc5 in spinal GABAergic interneurons via EZH2‐mediated histone modification, reducing Ca2+ influx and GABA release. TRPC5 activation enhances morphine analgesia, while EZH2 inhibition restores efficacy and reverses tolerance.

Mild Traumatic Brain Injury Evokes Pyramidal Neuron Axon Initial Segment Plasticity and Diffuse Presynaptic Inhibitory Terminal Loss

Frontiers in Cellular Neuroscience, 2017
The axon initial segment (AIS) is the site of action potential (AP) initiation, thus a crucial regulator of neuronal activity. In excitatory pyramidal neurons, the high density of voltage-gated sodium channels (NaV1.6) at the distal AIS regulates AP ...

LncRNA THUMPD3‐AS1 Regulates Behavioral and Synaptic Structural Abnormalities in Schizophrenia via miR‐485‐5p and ARHGAP8

Advanced Science, EarlyView.
Schizophrenia (SCZ) is linked to synaptic structural deficits driven by dysregulated noncoding RNAs. Using the novel ceRNAxis pipeline, THUMPD3‐AS1/miR‐485‐5p/ARHGAP8 is identified as a key regulator of actin cytoskeletal remodeling through noncanonical RhoB/C‐ROCK2 signaling. Modulating this axis ameliorates SCZ‐like phenotypes in mice and aligns with

Complex events initiated by individual spikes in the human cerebral cortex.

PLoS Biology, 2008
Synaptic interactions between neurons of the human cerebral cortex were not directly studied to date. We recorded the first dataset, to our knowledge, on the synaptic effect of identified human pyramidal cells on various types of postsynaptic neurons and

Stabilized Ion Selectivity Corrects Activation Drift in Kalium Channelrhodopsins

Advanced Science, EarlyView.
As newly emerged optogenetic tools, potassium channelrhodopsins (KCRs) can drift from inhibition to activation during illumination as K⁺ selectivity declines. It is shown that both the absolute K⁺/Na⁺ permeability ratio and its stability over time govern this drift, identify KCR1‐C29D as a reliably inhibitory variant, and outline design principles for ...

Ionic Permeability of the Inhibitory Postsynaptic Membrane of Lobster Muscle Fibers

The Journal of General Physiology, 1969
Reversal potentials (E IPSP) of the inhibitory postsynaptic potential and the membrane resting potentials (EM) of lobster muscle fibers were determined with intracellular recording under a variety of ionic conditions.
