Unilateral mastication‐induced memory deficits linked to disrupted hippocampal cholesterol metabolism in rats

VIEW, EarlyView.
Unilateral mastication, a common oral habit, induces cognitive decline in rats by disrupting hippocampal cholesterol metabolism. It triggers astrocyte hyperplasia, enhances cholesterol synthesis, impairs transport/degradation, and reduces 24‐hydroxycholesterol (24‐OHC), ultimately damaging synaptic function.

Hippocampal subfield differences in people with and without recreational ketamine use: Insights from multi‐modal neuroimaging

Addiction, EarlyView.
Abstract Background and aims Recreational ketamine use has increased globally and is associated with psychiatric and cognitive concerns. The hippocampus in preclinical models shows damage and working‐memory disruption with repeated dosing. However, whether specific hippocampal subregions may differ in people with chronic ketamine use remains unclear ...

The CA3 “backprojection” to the dentate gyrus [PDF]

, 2007
The hippocampus is typically described in the context of the trisynaptic circuit, a pathway that relays information from the perforant path to the dentate gyrus, dentate to area CA3, and CA3 to area CA1. Associated with this concept is the assumption that most hippocampal information processing occurs along the trisynaptic circuit.

A unified 3D reconstruction of microscopy and MRI in a brain showing Alzheimer's disease‐related neuropathology

Brain Pathology, EarlyView.
Post mortem MRI was combined with neuropathological assessments at 600 μm intervals throughout the brain. Through this approach, a three dimensional account of an entire human brain with an intermediate Alzheimer's disease neuropathologic change was created.

3D imaging of neuronal inclusions and protein aggregates in human neurodegeneration by multiscale x‐ray phase‐contrast tomography

Brain Pathology, EarlyView.
x‐ray phase‐contrast tomography enabled three‐dimensional, label‐free visualization and quantification of protein aggregates in neurodegenerative diseases with isotropic submicrometer resolution. The study revealed distinct electron density patterns in Lewy bodies, Hirano bodies, granulovacuolar degeneration, and amyloid plaques, highlighting their ...

Calponin‐3 is associated with epilepsy through the regulation of astrocyte activity

Brain Pathology, EarlyView.
Increased calponin‐3 expression correlates with astrocyte activation in epileptic mice, modulating adenosine metabolism regulators ADK and ENT1. Calponin‐3 overexpression increased susceptibility to epileptic seizures, while its downregulation reduces spontaneous recurrent seizures, identifying it as a potential therapeutic target for epilepsy ...

Alzheimer's disease and mixed pathologies as a hidden contributor to fatal hypothermia: A large‐scale forensic autopsy‐based study

Brain Pathology, EarlyView.
We investigated neuropathological manifestations of hypothermia in 168 cases. Patients aged 65 years or more constituted 80% of the total cohort. Alzheimer's disease was the most common comorbidity, affecting 40% of all patients. Abstract There is a paucity of autopsy‐based studies providing detailed neuropathological characteristics of fatal ...

Tau‐targeting active immunotherapy slows progression and reduces pathology in mouse models of tauopathy

Brain Pathology, EarlyView.
The efficacy of the novel anti‐tau active immunotherapy, p5555kb, was tested using two mouse models of tau pathology. p5555kb inoculation increased the survival rate and reduced tau pathology in tau‐overexpressing P301L mice and decreased tau seeding in the brains of C57BL/6 mice injected with human‐purified Alzheimer's disease tau.
