Innovative Test Strip‐Based Colorimetric Sensors Integrated With Affinity Chromatography: Acetylcholinesterase Inhibitor Screening Breakthrough in Lycium Barbarum Leaves

Advanced Science, EarlyView.
Schematic diagrams illustrating the breakthrough in the screening of AChE inhibitors from LBL, and the research process of the pharmacodynamics of the NCP are presented. ABSTRACT Current Alzheimer's drugs exhibit limited effectiveness, highlighting the necessity for multi‐target treatments.

Single‐cell atlas of neuroglial dynamics in SNCA‐A53T Parkinson's disease mouse model

Animal Models and Experimental Medicine, EarlyView.
We performed single‐cell RNA sequencing of midbrain and striatal tissues from SNCA‐A53T Parkinson's disease (PD) mice, revealing glia‐enriched PD‐risk gene signatures and disease‐specific subpopulations. Transcriptional dysregulation of key TFs (e.g., Rorb, Foxc1) and enhanced neuroinflammatory signaling (SEMA, CCL, MIF) were identified.

Generation of App knock-in mice reveals deletion mutations protective against Alzheimer’s disease-like pathology

Nature Communications, 2018
To date, only one mutation in the gene for amyloid-beta precursor protein APP has been suggested to be protective against Alzheimer’s disease. Here, authors found using gene editing of a mutant App knock-in mouse line that deletion of the 3’UTR region is

Strategies for inducing diabetes in laboratory animals: Advances from chemical, surgical, immunologic, dietary, and genetic approaches

Animal Models and Experimental Medicine, EarlyView.
This review summarizes the principal experimental approaches used to induce diabetes in animal models. Strategies include chemical agents (streptozotocin, alloxan, dithizone, gold thioglucose), dietary interventions (high‐fat and high‐sugar diets), surgical methods (total or partial pancreatectomy), genetic models (db/db, ob/ob, Goto‐Kakizaki [GK ...

Microglia and amyloid precursor protein coordinate control of transient Candida cerebritis with memory deficits

Nature Communications, 2019
The potential links between infections and neurodegenerative disorders are unclear. Here, Wu et al. present a mouse model of low-grade candidemia characterized by highly localized cerebritis, accumulation of amyloid precursor protein and beta peptides ...

The liver‐brain axis: A multidimensional regulatory network implicated in Alzheimer's disease pathogenesis and clinical implications

Animal Models and Experimental Medicine, EarlyView.
Schematic diagram of the core pathways of the liver‐brain axis in regulating AD. The liver regulates cerebral Aβ deposition, tau phosphorylation, and neuroinflammation through pathways such as metabolic detoxification (urea cycle, ketone body metabolism, glutathione antioxidant system), molecular secretion (APOE, CRP, FGF21, IGF‐1), and Aβ clearance ...

Use of Peptides for the Management of Alzheimer’s Disease: Diagnosis and Inhibition

Frontiers in Aging Neuroscience, 2018
Alzheimer’s disease (AD) is a form of dementia and the most common progressive neurodegenerative disease (ND). The targeting of amyloid-beta (Aβ) aggregation is one of the most widely used strategies to manage AD, and efforts are being made globally to ...

Distribution of Big Tau Isoforms in the Human Central and Peripheral Nervous System

Annals of Neurology, EarlyView.
Objective Tau is widely studied in neurodegeneration, yet most work has focused on canonical brain tau isoforms. A longer isoform, “big tau,” produced by inclusion of exon 4a, is expressed in the peripheral nervous system (PNS) and central nervous system (CNS) regions.

Biophysical Characterization and Proteomic Analysis of Small Extracellular Vesicles Derived From Different Neural Cell Lines

Advanced NanoBiomed Research, EarlyView.
This study systematically compares small extracellular vesicles (sEVs) derived from four neural cell lines, revealing how cellular origin shapes vesicle biophysical properties and proteomic cargo. Distinct, lineage‐specific signatures linked to neuronal, astrocytic, and microglial functions are identified, highlighting the importance of cell source ...

Cross‐Species Single‐Cell Comparative Analysis Reveals Gluconeogenic Features of Hepatocytes in Ruminants

Animal Research and One Health, EarlyView.
In this study, we used cross‐species comparisons to identify ruminant hepatocyte features. We also identified potential genes and TFs involved in coordinating gluconeogenesis in ruminant hepatocytes. By integrating single‐cell data with population genetic analyses, we further identified candidate genetic variation in glucose metabolism and ...
