Photosensitizing Lipid Nanoparticles for Ferroptosis‐Enhanced Photodynamic Cancer Therapy via GPX4 Silencing

open access: yesAdvanced Healthcare Materials, EarlyView.
Photosensitizing lipid nanoparticles (PLNPs) are engineered by incorporating cholesterol–PEG–pheophorbide a into MC3‐based LNPs and encapsulating GPX4‐targeting siRNA. Upon light activation, PLNPs generate reactive oxygen species (ROS) while silencing GPX4 to induce ferroptosis.

An Ultrapotent, Ultraeconomical, Antifreeze Polypeptide

open access: yesAdvanced Materials, EarlyView.
Simple and inexpensive polypeptides composed of random copolymers of alanine and glutamic acid are effective antifreezes for applications in foods and biomedicine. The polypeptides, inspired by natural extremophile proteins, inhibit the growth of large ice crystals and prevent damage to sensitive biologics.

Inhibiting Liver‐Derived C3 Protein Rescues Anesthesia/Surgery‐Induced Cognitive Impairment, Synaptic Disorders, and Microglial Phagocytosis

open access: yesAdvanced Science, EarlyView.
This study provides evidence that anesthesia/surgery can induce the BBB breakdown and promote the release of hepatogenous C3 protein into the blood. This surgical dual factors ultimately drove C3 to cross the damaged BBB and selectively colocalize with C3aR in the hippocampus, which results in structural and functional injury of synapse, C3aR‐mediated ...
