alpha- and beta-secretase: profound changes in Alzheimer's disease.

Biochemical and biophysical research communications, 2003
The amyloid plaque, a neuropathological hallmark of Alzheimer's disease, is produced by the deposition of beta-amyloid (Abeta) peptide, which is cleaved from Amyloid Precursor Protein (APP) by the enzyme beta-secretase. Only small amounts of Abeta form in normal brain; more typically this is precluded by the processing of APP by alpha-secretase.

Early administration of RS 67333, a specific 5-HT4 receptor agonist, prevents amyloidogenesis and behavioral deficits in the 5XFAD mouse model of Alzheimer’s disease

Frontiers in Aging Neuroscience, 2013
Amyloid β (Aβ) accumulation is considered the main culprit in the pathogenesis of Alzheimer's disease (AD). Recent studies suggest that decreasing Aβ production at very early stages of AD could be a promising strategy to slow down disease progression ...

Activation of Dll4/Notch Signaling and Hypoxia-Inducible Factor-1 Alpha Facilitates Lymphangiogenesis in Lacrimal Glands in Dry Eye. [PDF]

PLoS ONE, 2016
By using hypoxia-inducible factor-1 alpha conditional knockout (HIF-1α CKO) mice and a dry eye (DE) mouse model, we aimed to determine the role played by delta-like ligand 4 (Dll4)/Notch signaling and HIF-1α in the lymphangiogenesis of lacrimal glands ...

Biomarker-Drug and Liquid Biopsy Co-development for Disease Staging and Targeted Therapy: Cornerstones for Alzheimer's Precision Medicine and Pharmacology. [PDF]

, 2019
Systems biology studies have demonstrated that different (epi)genetic and pathophysiological alterations may be mapped onto a single tumor's clinical phenotype thereby revealing commonalities shared by cancers with divergent phenotypes.

Divergent Roles of mGlu2 and mGlu3 Receptors in Amyloid‐β Production and Cognitive Dysfunctions in Alzheimer's Disease

Advanced Science, EarlyView.
This study explores the opposing effects of the mGluR2 and mGluR3 receptors on amyloid precursor protein processing. mGluR2 promotes amyloidogenic cleavage, while mGluR3 favors non‐amyloidogenic pathways. Using a brain‐penetrant nanobody as a mGluR2 positive allosteric modulator, the study uncovers how its chronic activation aggravates amyloid‐β burden

TREM2-dependent effects on microglia in Alzheimer\u27s Disease [PDF]

, 2018
Alzheimer’s disease (AD) is a late-onset dementia characterized by the deposition of amyloid plaques and formation of neurofibrillary tangles (NFTs) which lead to neuronal loss and cognitive deficits.

Somatic cell reprogramming for Parkinson's disease treatment

Ibrain, Volume 11, Issue 1, Page 59-73, Spring 2025.
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option

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 ...
