Spatial multi‐omics identifies a NOTCH3‐mediated capillary–mCAF crosstalk driving immune exclusion in hepatocellular carcinoma

iMeta, EarlyView.
Spatial multi‐omics defines a DLL4–NOTCH3–driven capillary–mCAF axis orchestrating fibrotic remodeling and immune exclusion in hepatocellular carcinoma tumor cores, conferring immune checkpoint blockade resistance. Targeting stromal NOTCH3 disrupts this pro‐fibrotic niche, enhances T cell infiltration, and synergizes with anti‐PD‐1 therapy ...

BACE1 (β-secretase) knockout mice do not acquire compensatory gene expression changes or develop neural lesions over time

Neurobiology of Disease, 2003
The formation of Alzheimer's Aβ peptide is initiated when the amyloid precursor protein (APP) is cleaved by the enzyme β-secretase (BACE1); inhibition of this cleavage has been proposed as a means of treating Alzheimer's disease.

The Alzheimer's disease β-secretase enzyme, BACE1 [PDF]

, 2007
The pathogenesis of Alzheimer's disease is highly complex. While several pathologies characterize this disease, amyloid plaques, composed of the β-amyloid peptide are hallmark neuropathological lesions in Alzheimer's disease brain.

High‐ and Ultra‐High‐Frequency Ultrasound Identifies a Subclinical Link Between Suppurative Comedonal Nevus and Hidradenitis Suppurativa

Journal of Ultrasound in Medicine, EarlyView.
Suppurative nevus comedonicus (SNC) is a variant of nevus comedonicus in which the characteristic features coexist with recurrent inflammatory lesions that clinically resemble those of hidradenitis suppurativa (HS). We present the ultrasound characteristics of this entity and emphasize the value of high‐resolution dermatologic ultrasound both as a ...

Targeting neuroinflammation in Alzheimer’s disease [PDF]

, 2016
Almost 47 million people suffer from dementia worldwide, with an estimated new case diagnosed every 3.2 seconds. Alzheimer’s disease (AD) accounts for approximately 60%–80% of all dementia cases. Given this evidence, it is clear dementia represents one

Multi‐Targeting Ligands as Prospective Therapeutics for Alzheimer's Disease, a Prevalent Neurodegenerative Disorder: Mechanistic Insights, Emerging Targets and Drug Discovery Campaigns

Medicinal Research Reviews, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a debilitating neurodegenerative condition characterized by progressive cognitive impairment, memory deterioration, and neuronal dysfunction. Its complex pathophysiology involves multiple interlinked processes, including amyloid‐β (Aβ) aggregation, tau hyperphosphorylation, oxidative stress, neuroinflammation ...

The Large Ectodomain of APP Prevents APP from being Directly Cleaved by γ-Secretase

Frontiers in Bioscience-Landmark
Background: Alzheimer’s disease (AD) is characterized by the deposition of amyloid-β peptide (Aβ) in the brain. Aβ is produced by sequential β- and γ-secretase cleavages of amyloid precursor protein (APP).

In Silico Structure‐Guided Design of Peptide Candidates Targeting γ‐Secretase Subunit Assembly

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The γ‐secretase complex is a membrane‐embedded protease essential for intramembrane cleavage of substrates such as Notch receptors and the amyloid precursor protein (APP), processes central to cancer progression and Alzheimer's disease (AD) pathology.

AMPK in the central nervous system: physiological roles and pathological implications [PDF]

, 2016
5′ AMP-activated protein kinase (AMPK) is considered the master metabolic regulator in all eukaryotes, as it maintains cellular energy homeostasis in a variety of tissues, including the brain.

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

Small Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...
