Chrysanthemum morifolium extract protects HT22 cells from oxidative stress and enhances sleep via GABAergic modulation: contribution of luteolin‐7‐glucoside

Journal of the Science of Food and Agriculture, Volume 106, Issue 4, Page 2100-2110, 15 March 2026.
Abstract BACKGROUND Chrysanthemum morifolium has long been utilized in traditional medicine for its antioxidant and sedative properties, yet its potential in sleep regulation and neuroprotection against oxidative stress remains underexplored. This study investigates the antioxidant and sleep‐enhancing effects of C.

Müller Glial Kir4.1 Channel Dysfunction in APOE4‐KI Model of Alzheimer's Disease

Glia, Volume 74, Issue 3, March 2026.
APOE4 impairs Müller cell health by reducing Kir4.1 expression and buffering. APOE4 causes mitochondrial dysfunction with decreased ΔΨm and increased ROS. MitoQ restores Kir4.1 expression and reduces ROS in APOE4‐transfected cells. ABSTRACT Alzheimer's disease (AD), particularly late‐onset AD (LOAD), affects millions worldwide, with the apolipoprotein ...

Choroid plexus alterations in long COVID and their associations with Alzheimer's disease risks

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Choroid plexus (ChP) enlargement is a neuroimaging biomarker of neuroinflammation and neurodegeneration. However, evidence of ChP structural and perfusion alterations in long coronavirus disease (COVID) and their clinical relevance remains limited.

The Association between Glymphatic System and Perivascular Macrophages in Brain Waste Clearance

Diagnostics
The glymphatic system suggests the convective bulk flow of cerebrospinal fluid (CSF) through perivascular spaces and the interstitial spaces of the brain parenchyma for the rapid removal of toxic waste solutes from the brain.

Impaired adrenergic regulation of Kv channels underlies LC hyperactivity and early‐onset sleep disruption in AD‐like amyloidogenic mice

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Sleep–wake disturbances frequently occur at early stages of Alzheimer's disease (AD) and accelerate disease progression, but the underlying neural mechanisms are not fully understood. METHODS We examined sleep–wake behavior and locus coeruleus (LC) activity in young 5xFAD mice using electrophysiology and pharmacological approaches

APP‐mediated intracellular signaling rescues sleep impairment and blood–brain barrier leakage in Alzheimer's disease mouse model

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Amyloid beta peptide (Aβ) accumulation in the brain is an Alzheimer´s disease (AD) hallmark. Sleep disturbances hamper Aβ production and clearance, thereby exacerbating the Aβ burden. The mechanisms involved remain unclear. We reported that amyloid precursor protein (APP), the Aβ source, possesses intracellular signaling that ...

Neurologic symptoms as a hallmark of glymphatic alteration in recovered patients with COVID-19

BMC Neurology
Background The glymphatic system is a glial-based perivascular network that facilitates the clearance of metabolic waste from the brain. Dysfunction of the glymphatic system, along with neurological symptoms such as cognitive deficits and olfactory ...

Relationship between locus coeruleus and slow‐wave sleep in aging and Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Sleep disruption, particularly loss of slow‐wave sleep (SWS), is common in Alzheimer's disease (AD), but its neurobiological underpinnings remain unclear. We investigated whether locus coeruleus (LC) integrity relates to SWS across the AD continuum and whether sex and perivascular spaces (PVSs) modify these associations.
