Transcriptional Mechanisms of Neuroprotection in Excitotoxicity Driven Neurodegeneration in \u3ci\u3eC. elegans\u3c/i\u3e [PDF]

, 2022
Excitotoxicity is notorious for triggering neuronal cell death in both developmental and adult-onset neurodegenerative diseases. In excitotoxicity, excessive concentrations of Glutamate in the synapse overstimulate Glutamate Receptors (GluRs) on ...

Modulation of Presynaptic Inhibitory Retinal Circuits for Retinal Ganglion Cell Neuroprotection in Glaucoma

Advanced Science, EarlyView.
Ocular hypertension induces early hyperactivity in inner retinal inhibitory circuitry before substantial retinal ganglion cell loss. Sustained pharmacological inhibition of GABAergic/glycinergic neurotransmission and Vgat‐targeted Lin28 expression suppress this hyperactivity and improve RGC survival without reducing intraocular pressure. These findings

VEGFD Protects Retinal Ganglion Cells and, consequently, Capillaries against Excitotoxic Injury

Molecular Therapy: Methods & Clinical Development, 2020
In the central nervous system, neurons and the vasculature influence each other. While it is well described that a functional vascular system is trophic to neurons and that vascular damage contributes to neurodegeneration, the opposite scenario in which ...

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

Advanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

Serum Magnesium Levels and Lipid Profile in Patients with Epileptic Seizures: A Cross-sectional Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Recurrent seizures of cerebral origin with episodes of sensory, motor, or autonomic expression, with or without loss of consciousness, are typical symptoms of epilepsy, a chronic neurological condition.

The Redox Biology of Excitotoxic Processes: The NMDA Receptor, TOPA Quinone, and the Oxidative Liberation of Intracellular Zinc

Frontiers in Neuroscience, 2020
This special issue of Frontiers in Neuroscience-Neurodegeneration celebrates the 50th anniversary of John Olney’s seminal work introducing the concept of excitotoxicity as a mechanism for neuronal cell death.

A Biomimetic PLK1 Nanodelivery System Promotes Migrasome‐Mediated Mitocytosis to Restore Efferocytosis and Functional Recovery After Spinal Cord Injury

Advanced Science, EarlyView.
MM‐NPs@PLK1 are formed by encapsulating PLK1 plasmids within CBP5 and coating the nanocomplexes with macrophage membranes. After macrophage‐associated uptake, the NPs@PLK1 enter the cytoplasm and release the PLK1‐encoding plasmid in response to elevated intracellular ROS levels.

Animal stroke models and outcome evaluation: A review

Animal Models and Experimental Medicine, EarlyView.
Rodents are the preeminent stroke model species. Large animal models exist too, but are poorly standardized. Ischemic and hemorrhagic experimental models are available, with the intraluminal filament model being predominant. Outcomes are evaluated via quantifying subjects' sensorimotor impairment, cognitive memory faculties, degree of cellular ...

CD3ζ-Mediated Signaling Protects Retinal Ganglion Cells in Glutamate Excitotoxicity of the Retina

Cells
Excessive levels of glutamate activity could potentially damage and kill neurons. Glutamate excitotoxicity is thought to play a critical role in many CNS and retinal diseases.
