Polystyrene Nanoplastics Drive β‐Cell Dedifferentiation Through Dendritic Cell‐Intrinsic MHC‐I‐Dependent Inflammatory Crosstalk

Advanced Science, EarlyView.
Polystyrene nanoplastics disrupt pancreatic immune–endocrine homeostasis by promoting MHC‐I‐associated dendritic cell activation and inflammatory crosstalk with β cells. This immune remodeling drives β‐cell dedifferentiation, impairs insulin secretion, and aggravates metabolic dysfunction, revealing a previously unrecognized immunometabolic mechanism ...

Amyloid-β Peptide-targeting Immunotherapy in Alzheimer Disease: A Systematic Review of Clinical Studies [PDF]

Caspian Journal of Neurological Sciences
Background: Amyloid-β (Aβ) peptide accumulation in the brain is a pathological hallmark of Alzheimer disease (AD). Because of the relationship between the Aβ plaque formation and AD progression, targeting Aβ has been advocated as a treatment strategy for

Beyond PEG: Emerging Polymer Lipid Alternatives for Lipid Nanoparticle (LNP) Formulations

Advanced Science, EarlyView.
This review discusses recent advances in PEG‐alternative LNP designs, including non‐PEG polymers, zwitterionic lipids, and polypeptides. It evaluates how surface‐engineering chemistry influences LNP formation and biological behavior, and highlights current limitations and opportunities of PEG‐alternative LNPs.

Analysis of high density lipoprotein apolipoproteins by capillary zone and capillary SDS gel electrophoresis

Journal of Lipid Research, 1998
We describe new methods for analyzing the apolipoproteins (apo) of the high density lipoproteins (HDL) of several species by two modes of capillary electrophoresis: size separation using a molecular sieving buffer, and capillary zone electrophoresis (CZE)

Phase Separation of TRIM21 Modulates PTPN14 Stability to Drive Flow‐Dependent Endothelial Activation and Atherogenesis

Advanced Science, EarlyView.
Disturbed flow promotes the formation of TRIM21‐rich biomolecular droplets, which concentrate TRIM21 and PTPN14 and facilitate their SPRY‐FERM interaction (illustrated by the TRIM21 D355‐PTPN14 R132 salt bridge). This condensate‐driven proximity enables TRIM21 to catalyze K48‐linked polyubiquitination of PTPN14 at lysine 956, leading to proteasome ...

Apolipoprotein E Polymorphism and Lipid Metabolism Disorders in Children with Cholelithiasis

Zdorovʹe Rebenka, 2016
Relevance. The incidence of cholelithiasis in children in Ukraine has increased from 0.1–1 to 4.8 % in the structure of biliary pathology [6, 9, 13]. Rising the incidence of cholelithiasis in childhood is obvious, but the reasons are not clear.
