Ca2+-Dependent Induction of Intracellular Ca2+ Oscillation in Hippocampal Astrocytes During Metabotropic Glutamate Receptor Activation

Journal of Pharmacological Sciences, 2005
We have investigated whether the intracellular calcium concentration ([Ca2+]i) oscillations induced in astrocytes using the metabotropic glutamate-receptor agonist, (1S,3R)-1-aminocyclopentane-1,3-dicarboxylic acid (t-ACPD) are Ca2+-dependent, using ...

Alcohol-drinking during later life by C57BL/6J mice induces sex- and age-dependent changes in hippocampal and prefrontal cortex expression of glutamate receptors and neuropathology markers

Addiction Neuroscience, 2023
Heavy drinking can induce early-onset dementia and increase the likelihood of the progression and severity of Alzheimer's Disease and related dementias (ADRD).

Hyperhomocysteinemia‐Driven Ischemic Stroke: Unraveling Molecular Mechanisms and Therapeutic Horizons

Food Science &Nutrition, Volume 13, Issue 7, July 2025.
Neurotoxicity of Hcy. (A figure that best represents the scope of the paper.) Homocysteine can reduce the tightness of endothelial cell connections, increase vascular permeability, and damage the blood–brain barrier. Homocysteine activates various glutamate receptors on the surfaces of neurons and glial cells, triggering excitotoxicity, promoting the ...

Stimulation of microglial metabotropic glutamate receptor mGlu2 triggers tumor necrosis factor alpha-induced neurotoxicity in concert with microglial-derived fas ligand [PDF]

, 2005
Activated microglia may be detrimental to neuronal survival in a number of neurodegenerative diseases. Thus, strategies that reduce microglial neurotoxicity may have therapeutic benefit.

Temporal Profiling of Male Cortical Astrocyte Transcription Predicts Molecular Shifts From Early Development to Aging

Glia, Volume 73, Issue 7, Page 1349-1364, July 2025.
Main Points Comprehensive analysis of cortical astrocyte gene expression across the lifespan. Profiling dynamic changes of key astrocyte genes reveals functional shifts. Astrocytes contribute to gene‐length‐dependent transcription decline in the aging brain.

Protocol for interfering peptide injection into adult mouse hippocampus and spatial memory testing

STAR Protocols, 2021
Summary: Metabotropic glutamate receptor-dependent long-term depression (mGluR-LTD) occurs in diverse brain regions and contributes to the plasticity of behavior, learning, and memory. mGluR-LTD relies on rapid (in minutes) local protein synthesis. Here,

Multi‐Omic Analysis Reveals Astrocytic Annexin‐A2 as Critical for Network‐Level Circadian Timekeeping in the Suprachiasmatic Nucleus

Glia, Volume 73, Issue 7, Page 1483-1501, July 2025.
Main Points Multi‐omics reveal Annexin‐A2 (A2) and S100a10 (A10) as SCN astrocyte enriched proteins. Disrupting A2‐A10 complex elevates astrocyte Ca2+ and compromises SCN timekeeping. Astrocytic A2‐A10 is a critical control point for SCN network rhythms.

Direct and indirect pathways for heterosynaptic interaction underlying developmental synapse elimination in the mouse cerebellum

Communications Biology
Developmental synapse elimination is crucial for shaping mature neural circuits. In the neonatal mouse cerebellum, Purkinje cells (PCs) receive excitatory synaptic inputs from multiple climbing fibers (CFs) and synapses from all but one CF are eliminated
