Given their functional significance, there are intense research interests to use EVs as disease markers and drug carriers. However, EVs characterization is greatly hindered by the small size, the low biomolecule payload, and the high level of heterogeneity. To address these challenges, researchers have adopted sensitive microscopic methods such as single-molecule fluorescence imaging, single-particle dark-field imaging, surface-enhanced Raman scattering, and surface plasmon resonance imaging for single EV analysis. These techniques can detect signals from individual EVs, enabling a detailed study of the heterogeneity. Analysis of EVs cargo has provided insights into the protein/nucleic acid expression and enabled subgroup differentiation. Superresolution mapping has visualized EVs structures, and single EV tracking has offered insights into their release and uptake mechanisms. In this review, we will summarize the recent advances in optical imaging of single EVs, including the biomarkers used for EV labeling, the performance of the reported microscopic methods, and their biological findings.

Unfortunately, traditional strategies are complicated and insufficiently accurate due to the widely used single-target screening method. Herein, a simple dual-target-based drug-screening strategy (dt-DSS) is proposed to screen highly effective drugs by fluorescence imaging. As a proof of concept, we utilized a dual-responsive fluorescence probe to screen drugs for diabetic cardiomyopathy (DCM). We first developed and took advantage of a dual-response probe HDB to detect reactive oxygen species (ROS) and mitophagy levels in cellular starvation and high glucose models. Based on this, HDB was utilized to study the effects of different drugs in the mitophagy process caused by the high-glucose cell model for DCM. Combined with Western blotting assays, we found that Drp-1 inhibitors could fundamentally reduce mitophagy caused by the high-glucose cells model. Compared with commercial single-target antioxidant drugs, the drugs with simultaneous antioxidant capacity and Drp-1 inhibition screened by dt-DSS, such as resveratrol and icariin, could treat DCM better. Therefore, HDB as an effective tool could accurately and quickly screen high-potency drugs for DCM. We believe that this work provides an attractive strategy to explore the pathogenesis of diabetic cardiomyopathy and precisely screen for highly effective drugs.</p>","PeriodicalId":53181,"journal":{"name":"Chemical & Biomedical Imaging","volume":"2 3","pages":"185–193"},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/cbmi.3c00112","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138980637","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}

Here, we report a DNA nanotechnology-based platform for reversible manipulation and localized analysis of lipid rafts, which consists of two modules: “patching and coding probe pair” and “fishing probe”. The probe pair is generated by modifying two different sets of connectable DNA structures on a lipid raft-specific protein. After recognizing lipid rafts, the two probes in close proximity are linked by a DNA ligase reaction to form a lipid raft identity (LR-ID) code. The LR-ID strand patches and stabilizes the lipid raft structure. Interestingly, the raft patches formed can be depatched by restriction endonucleases, providing the first reversible manipulation of the lipid raft structure in living cells. We also designed a “fishing probe” with a DNA hairpin structure using an aptamer that can specifically bind to the target. The probe can cascade the reaction to two input signals “LR-ID” and “target protein” to generate an “off–on” fluorescence switch, allowing imaging and dynamic monitoring of target proteins localized in lipid rafts. By encoding arbitrary targets (in the case of glycans) in lipid rafts, we have created a universal lipid raft-localized imaging platform.

This emerging field has been coined “nanoscale brachytherapy”. Despite present-day advancements, an ongoing challenge is obtaining an advanced, functional nanomaterial that concurrently incorporates features of high radiolabeling yield, short labeling time, good radiolabeling stability, and long tumor retention time without leakage of radioactivity to the nontargeted organs.

Our code processes multichannel, time-lapse microscopy videos of cocultured CN and immune cells that have each been fluorescently stained with unique dyes and provides quantitative readouts of the spatiotemporally dynamic process that is vomocytosis. This study also explored metrics, such as the rate of change of pathogen colocalization with the host cell, that could potentially be used to predict vomocytosis occurrence based on the quantitative data collected. Ultimately, the algorithm quantifies vomocytosis events and reduces the time for video analysis from over 1 h to just 10 min, a reduction in labor of 83%, while simultaneously minimizing human error.
