Conformational pathway provides unique sensitivity to a synaptic mGluR

Nature Communications, 2019
Metabotropic glutamate receptors (mGluRs) are dimeric G-protein–coupled receptors that operate at neural synapses. Here authors use FRET assays in live cells to monitor mGluR2/7’s activation and reveal how heterodimerization can alter the glutamate ...

Purinergic and muscarinic modulation of the cell cycle and calcium signaling in the chick retinal ventricular zone [PDF]

, 2002
Spontaneous calcium transients occur in the ventricular zone of the chick retina and result from the endogenous release of neurotransmitters in the absence of action potentials.

Multiscale Coupling From Mastication to Retronasal Aroma Perception: The PG‐DTCFN Model and Multiphysics Simulation

Advanced Science, EarlyView.
Using grilled lamb skewers as a model system, this work builds a multiscale coupling framework from oral processing to retronasal aroma perception, reveals dual‐kinetic release patterns and Electroencephalogram‐characterized central encoding features, and proposes an interpretable physics‐guided deep learning model validated by multiphysics simulation,

Group-I metabotropic glutamate receptors: hypotheses to explain their dual role in neurotoxicity and neuroprotection

, 1999
The role of group-I metabotropic glutamate receptors (mGlu1 and 5) in neurodegeneration is still controversial. While antagonists of these receptors are consistently neuroprotective, agonists have been found to either amplify or attenuate excitotoxic ...

Functionalized Biomimetic Scaffolds for Human‐Derived Auditory Neural Circuit Construction

Advanced Science, EarlyView.
In Vitro Auditory Circuit Model. ABSTRACT Damage to auditory circuits results in sensorineural hearing loss. However, the scarcity of human inner ear tissue significantly hinders the development of therapies to preserve auditory function, creating a critical need for reliable in vitro models.

Deconstruction of Human Age‐Related Cataract Capsules Defines Aging

Advanced Science, EarlyView.
We generate a comprehensive atlas of age‐related cataracts (ARC) at a single‐cell resolution, encompassing three disease states—mild cataract group (Mild), severe cortical cataract group (Severe_C), and severe nuclear cataract group (Severe_N). We find that ARC involves seven distinct lens capsule cell types, with notable differences in cellular ...

Targeted β‐Glucan‐Veiled Oral Apremilast Nanotherapy Modulates Key Dysbiosis‐Associated Gut Microbiota and Alleviates Ulcerative Colitis‐Associated Anxiety, Depression, and Neuropsychiatric Behaviors

Advanced Science, EarlyView.
This study introduces β‐glucan‐shielded apremilast laden nanomicelles that withstand gastrointestinal degradation, selectively accumulate in inflamed colon tissue, and modulate the microbiota–gut–brain axis. The formulation restores barrier integrity, reduces systemic and neuroinflammation, and improves anxiety‐ and depression‐like behaviors in colitis

Regulation of the microglial NADPH oxidase by neurotransmitters: implications for microglial – neuronal interactions [PDF]

, 2012
Neurotransmitter dysregulation and reactive oxygen species (ROS) are a hallmark of neurodegenerative disease. Microglia, the immune cells of the CNS, express three NADPH oxidase isoforms (Nox1, Nox2 and Nox4), which produce superoxide that is used as an ...

Neuropeptide Y—Graphene Oxide Complexes Inhibit Amygdala NPY‐Receptor Expressing Glutamatergic Pathways and Selectively Remove Aversive Memory In Vivo

Advanced Science, EarlyView.
A graphene oxide nanocarrier presents neuropeptide Y specifically to NPY receptor‐expressing pathways in the amygdala, whose activation selectively suppresses aversive memory formation, without modulating anxiety responses. This circuit‐restricted drug release strategy may impact future design of neuropsychiatric therapies with limited off‐target ...
