Bioorthogonally-Engineered Extracellular Vesicles for Applications in Detection and Therapeutic Delivery


Project TitleBioorthogonally-Engineered Extracellular Vesicles for Applications in Detection and Therapeutic Delivery
Track Code28938
Short Description

In the body, extracellular vesicles (EVs) are derived from the cellular membrane during the budding process and are vehicles used for the transport of mRNA and microRNA. Intrinsically biocompatible, EVs are promising as delivery carriers for drugs, therapeutics, or genes. However, there lacks a fast, convenient, and efficient way to synthetically functionalize EVs. Synthetic functionalization is highly desirable as a way to facilitate EVs to be purified, concentrated, and delivered properly post loading with desired cargo.

UCI researchers have developed a facile method for introducing binding sites on the surface of EVs. These binding sites serve as a platform to conjugate various molecules such as fluorescent groups or magnetic particles. The different types of molecules that can be conjugated enable the user to utilize the EVs for a variety of applications, ranging for molecular imaging to delivery of desired cargo to targeted tissues.


Extracellular vesicles (EVs) are promising as drug delivery carriers because they are inherently biocompatible, It would be desirable to efficiently, specifically, and rapidly change the EVs surface presentation to program the interactions with its target cells. Inventors at UC Irvine have developed a strategy for functionalizing the cellular membranes of EVs with precision and ease.
