Tetrandrine alleviates inflammation and neuron apoptosis in experimental traumatic brain injury by regulating the IRE1α/JNK/CHOP signal pathway

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Aim The aim of this study was to investigate the therapeutic roles of Tetrandrine (TET) on traumatic brain injury (TBI) and the underlying mechanism. Method Traumatic injury model of hippocampal neurons and TBI mouse model were established to evaluate the therapeutic effects.

Upconversion‐Based Remote Deep Brain Modulation for Therapeutic Dissection of Parkinson's Disease

Advanced Therapeutics, EarlyView.
An upconversion‐based wireless optogenetic strategy enables an all‐optical deep brain modulation solution for treating Parkinson's disease in rodent animals without using electronics or any tethered cables, providing experimental evidence supporting a therapeutic mechanism of STN‐DBS by disruption of anterograde signal transmission along the indirect ...

Activation of Glutamatergic Neurons in the Supramammillary Nucleus Promotes the Recovery of Consciousness under Sevoflurane Anesthesia

Advanced Science, EarlyView.
Selective lesioning of SuM glutamatergic neurons promoted the induction of and delayed emergence from sevoflurane anesthesia and increased sevoflurane sensitivity. Optogenetic stimulation of SuM glutamatergic neurons or the SuM‐MS projection promoted behavioral arousal and cortical activation under steady‐state sevoflurane anesthesia and reduced the ...

Fabrication and Functionalisation of Nanocarbon‐Based Field‐Effect Transistor Biosensors

ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
Next‐generation diagnostics: Nanocarbon‐based field effect transistors (NC‐FETs) use incoming target analytes to impart a gating effect on conductance. Here, we review the operational mechanisms behind NC‐FETs, the fabrication and functionalisation of NC‐FETs with receptor biomolecules and downstream biosensing applications.

Estimating the synaptic current in a multi-conductance AMPA receptor model [PDF]

, 2010
A pre-synaptic neuron releases diffusing neurotransmitters such as glutamate that activate post-synaptic receptors. The amplitude of the post-synaptic current, mostly mediated by glutamatergic (AMPARs) receptors, is a fundamental signal that may generate an action potential.

α‐Synuclein Pathology Spreads in a Midbrain–Hindbrain Assembloid Model

Advanced Science, EarlyView.
A novel midbrain–hindbrain assembloid model demonstrates the spread of α‐synuclein pathology, a hallmark of Parkinson's disease, mimicking Braak's hypothesis. This model reveals how pathology propagates from the hindbrain to the midbrain, inducing synaptic changes and early signs of neuronal vulnerability. It offers an innovative platform for exploring

Chemical Proteomics Reveals Protein Tyrosination Extends Beyond the Alpha‐Tubulins in Human Cells**

ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
Protein post‐translational modifications allow cells to swiftly adjust activity and localization of proteins. Here, we developed a chemical proteomic approach to determine a protein tyrosination status using an O‐propargyl tyrosine probe. We show that tyrosination modifies previously described alpha‐tubulins with ‐EEY C‐terminal sequence together with ...

Deciphering Auditory Hyperexcitability in Otogl Mutant Mice Unravels an Auditory Neuropathy Mechanism

Advanced Science, EarlyView.
By investigating auditory hyperexcitability in a mouse model for hereditary deafness, this study identified a subpopulation of afferent neurons of the auditory nerve marked by Otogl expression. Despite their apparently normal hearing, Otogl+/− mice display poor activation of afferent neurons processing loud sounds and an elevation of the middle the ear
