Surface engineering with pH-responsive polyserotonin and self-activated DNAzyme for better microbial therapy of tumor.

Bacteria-based microbial immunotherapy shows various unique properties for tumor therapy owing to their active tropism to tumor and multiple anti-tumor mechanisms. However, its clinical benefit is far from satisfactory, which is limited by rapid systemic clearance and neutrophils-mediated immune restriction to compromise the efficacy, as well as non-specific distribution to cause toxicity. To address all these limitations, herein we reported a polyserotonin (PST) coated () with surface adsorption of DNAzyme (Dz)-functionalized MnO nanoparticles (DzMN) for tumor therapy.

Supramolecular Assembly Based on Calix(4)arene and Aggregation-Induced Emission Photosensitizer for Phototherapy of Drug-Resistant Bacteria and Skin Flap Transplantation.

Photodynamic therapy as a burgeoning and non-invasive theranostic technique has drawn great attention in the field of antibacterial treatment but often encounters undesired phototoxicity of photosensitizers during systemic circulation. Herein, a supramolecular substitution strategy is proposed for phototherapy of drug-resistant bacteria and skin flap repair by using macrocyclic p-sulfonatocalix(4)arene (SC4A) as a host, and two cationic aggregation-induced emission luminogens (AIEgens), namely TPE-QAS and TPE-2QAS, bearing quaternary ammonium group(s) as guests. Through host-guest assembly, the obtained complex exhibits obvious blue fluorescence in the solution due to the restriction of free motion of AIEgens and drastically inhibits efficient type I ROS generation.

Lipidomics Analysis in Ferroptosis.

Ferroptosis is a form of regulated cell death that occurs due to abnormal lipid metabolism. Lipids, which have been identified in over 45,000 different molecular species, play essential roles in modulating basic life processes. The process of ferroptosis is highly reliant on various lipid species, with polyunsaturated fatty acids (PUFAs) playing a central role in driving this process.

The bio-functionalized membrane loaded with Ta/WH nanoparticles promote bone regeneration through neurovascular coupling.
