The effects of peripheral and central high insulin on brain insulin signaling and amyloid-β in young and old APP/PS1 mice [PDF]

, 2016
Hyperinsulinemia is a risk factor for late-onset Alzheimer's disease (AD). In vitro experiments describe potential connections between insulin, insulin signaling, and amyloid-β (Aβ), but in vivo experiments are needed to validate these relationships ...

Impaired glymphatic transport in hypoxic-ischemic encephalopathy

NeuroImage
Hypoxic-ischemic encephalopathy (HIE) is a major cause of neonatal brain injury. The glymphatic system aids in waste clearance via perivascular pathways and is crucial in maintaining brain functions.

Attenuation of cerebral edema facilitates recovery of glymphatic system function after status epilepticus

JCI Insight, 2021
Status epilepticus (SE) is a neurological emergency usually accompanied by acute cerebral edema and long-term cognitive impairment, and is characterized by neurodegeneration and aberrant hyperphosphorylated tau protein (p-tau) aggregation.

The Ocular Glymphatic Clearance System [PDF]

, 2019
AbstractDespite high metabolic activity, the retina and optic nerve head lack traditional lymphatic drainage. We here identified a novel ocular glymphatic clearance route for fluid and wastes via the proximal optic nerve. Amyloid-β (Aβ) was cleared from the vitreous via a pathway driven by the ocular-cranial pressure difference.

Transplantation of GABAergic Interneuron Progenitors Restores Cortical Circuit Function in an Alzheimer's Disease Mouse Model

Advanced Science, EarlyView.
Transplantation of medial ganglionic eminence (MGE) interneuron progenitors into APP/PS1 cortices restored the slow oscillation characteristic of Alzheimer's disease. Donor cells survived, migrated, and matured into functional GABAergic interneurons, forming synaptic connections.

A mixed finite element method for nearly incompressible multiple-network poroelasticity

, 2018
In this paper, we present and analyze a new mixed finite element formulation of a general family of quasi-static multiple-network poroelasticity (MPET) equations.

NIR-II nanoprobes for investigating the glymphatic system function under anesthesia and stroke injury

Journal of Nanobiotechnology
The glymphatic system plays an important role in the transportation of cerebrospinal fluid (CSF) and the clearance of metabolite waste in brain. However, current imaging modalities for studying the glymphatic system are limited.

Targeting the glymphatic system to promote α-synuclein clearance: a novel therapeutic strategy for Parkinson’s disease

Neural Regeneration Research
The excessive buildup of neurotoxic α-synuclein plays a pivotal role in the pathogenesis of Parkinson’s disease, highlighting the urgent need for innovative therapeutic strategies to promote α-synuclein clearance, particularly given the current lack of ...

Glymphatic Dysfunction Induced Oxidative Stress and Neuro-Inflammation in Major Depression Disorders

Antioxidants, 2022
Major Depression disorder (MDD) is a potentially life-threatening mental illness, however, many patients have a poor response to current treatments. Recent studies have suggested that stress- or trauma-induced oxidative stress and inflammation could be ...
