However, particularly the visualization of lipids such as cholesterol—a central compound of cell membranes—with high spatial resolution remains challenging because they cannot be efficiently immobilized for super-resolution microscopy investigations. Here we developed an azido- and amino-modified cholesterol probe that can be efficiently fixed and labeled with fluorophores by click chemistry. In combination with expansion microscopy, its cellular localization and interaction with other cellular proteins can be precisely determined in fixed cells at varying time points after addition. Our approach allows us to detect the endocytic pathway of cholesterol with unprecedented spatial resolution and shows that cholesterol is efficiently ingested in endocytic vesicles and accumulates as cholesterol aggregates with an average size of ∼37 nm in late endosomes and lysosomes, respectively.</p>","PeriodicalId":72127,"journal":{"name":"Aggregate (Hoboken, N.J.)","volume":"6 8","pages":""},"PeriodicalIF":13.7,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agt2.70104","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single-crystal X-ray diffraction analysis was conducted on four distinct compounds isolated during the reaction, and electrospray ionization mass spectrometry (ESI-MS) of both solid products and intermediate reaction solutions enabled the identification of 15 consecutive reaction steps, where Fe(III) was directly involved in eight steps. These transformations comprise nine intermolecular C─C coupling events and six intramolecular ring expansion processes. The heteroatoms (N, O, and S) play distinct mechanistic roles according to their positions within the heterocyclic framework: (1) nitrogen and oxygen coordinate with Fe(III), facilitating activation of the reaction site; (2) homolytic cleavage of the C─O bond promotes C─C coupling reactions; and (3) C─S migration induces intramolecular ring expansion. Notably, theoretical calculations indicate a decrease in Gibbs free energy along the intramolecular reaction pathways, substantiating the proposed mechanism and activation mode, which underscores the essential role of Fe(III) in enabling the reaction progression. Furthermore, an investigation of the photophysical properties revealed that the resulting heterocyclic aggregates exhibit strong luminescence within the 535–610 nm wavelength range, approaching the near-infrared region. These findings highlight the significance of this reaction pathway in the controlled synthesis of functional oligomers and polymers from monomeric precursors, particularly through catalysis by cost-effective metal ions.</p>","PeriodicalId":72127,"journal":{"name":"Aggregate (Hoboken, N.J.)","volume":"6 8","pages":""},"PeriodicalIF":13.7,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agt2.70094","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a novel fluorescence immunoassay strategy that leverages the spontaneous amino-yne click reaction to covalently assemble activated alkyne-based luminogens with aggregation-induced emission characteristics (AIEgens) onto the surface of bifunctional M13 bacteriophages, thereby facilitating efficient “lighting-up” fluorescence signal output in conjunction with magnetic-mediated immunorecognition. To further enhance the load of activated alkyne-based AIEgens and improve the fluorescence “lighting-up” efficiency, M13 bacteriophages were engineered to display varying numbers of surface-exposed lysine residues. This was achieved by inserting different quantities of lysines between the signal peptide and the amino acid sequence of the pVIII protein via a point mutation strategy. Benefiting from the synergy of AIEgen stacking-enhanced fluorescence output and M13 bacteriophage-driven signal amplification, the developed “lighting-up” immunoassay enabled highly sensitive and rapid detection of targets, from small molecules to pathogenic microorganisms. This work provides valuable insights into the design of “lighting-up” AIEgens for enhancing fluorescence immunoassays.

To address these challenges, a flexible hydrogel (LM@P/S@CP@Hemin) that involves flexible wood-modified logs, photoactive conjugated polymers, an immunomodulator, and an immobilization hydrogel was prepared for nasal cavity treatment. The flexible wood-modified logs provide mechanical strength support. In vitro, experiments verified that the hydrogel could efficiently induce the photothermal effect under near-infrared-II laser irradiation after deeply penetrating bone and produce reactive oxygen species (ROS) to initiate the photodynamic effect for synergetically eliminating bacteria. The introduction of hemin endows LM@P/S@CP@Hemin hydrogel with a strong immunomodulatory effect on macrophages to achieve anti-inflammation and cellular ROS clearance abilities, which avoids the excessive oxidative stress in the nasal cavity. The results showed that the hydrogel induced an anti-bacterial effect with a 98.5% inhibition rate against methicillin-resistant <i>Staphylococcus aureus</i>, hadexcellent clearance ability of excessive ROS, and promoted anti-inflammatory M2 macrophage generation to relieve inflammation. Meanwhile, transcriptome sequencing and mRNA level measurements revealed that the hydrogel could regulate inflammatory-related genes. In vivo, bacterial infection-induced acute sinusitis rabbit model experiments and histological analysis further confirmed the great therapeutic effect of LM@P/S@CP@Hemin for acute sinusitis based on photothermal and photodynamic therapy.
