Summary of "Rapid Detection of Exosomal MicroRNAs Using Virus-Mimicking Fusogenic Vesicles."

Exosomal microRNAs (miRNAs) are important biomarkers for clinical diagnosis and disease treatment monitoring. However, most approaches for exosomal miRNA detection are time-consuming, laborious, and expensive. Herein, we report a virus-mimicking fusogenic vesicle (Vir-FV) that enables rapid, efficient, and high-throughput detection of exosomal miRNAs within 2 h. Fusogenic proteins on Vir-FVs can specifically target the sialic-acid-containing receptors on exosomes, inducing efficient fusion of Vir-FVs and exosomes. Upon vesicle content mixing, the molecular beacons encapsulated in Vir-FVs specifically hybridize with the target miRNAs in the exosomes, generating fluorescence. Combined with flow cytometry, the Vir-FVs can not only detect exosomal miRNAs but also distinguish tumor exosomes from normal exosomes by sensing the tumor-related miRNAs, paving the way towards the rapid and efficient detection of exosomal miRNAs for diagnosis and prognosis prediction of diseases.
