Fusosome composition for delivering biologic agents to target cells
A patent application (Publication Number: US20240033227A1) describes a fusosome composition that includes multiple fusosomes derived from a source cell. These fusosomes consist of a lipid bilayer, a lumen containing cytosol from the source cell, an exogenous or overexpressed fusogen (such as specific viral proteins), and cargo. Notably, the fusosomes do not contain a nucleus, and the viral capsid protein content is minimal. Additionally, some fusosomes may include a targeting moiety specific to certain cell surface markers, enabling precise delivery to skin cells, cardiomyocytes, hepatocytes, and other cell types. The fusosomes may vary in size and can be derived from various cell types, including neutrophils, stem cells, and neurons.
Furthermore, the patent application outlines the use of this fusosome composition in pharmaceutical compositions for delivering therapeutic agents to subjects. By administering these compositions, the cargo can be effectively delivered to the target cells, offering a potential method for targeted drug delivery. The fusosome composition can be tailored to include specific fusogens and cargoes, enhancing its versatility for various applications. The absence of viral capsid proteins in the fusosomes is a notable feature, ensuring the safety and efficacy of the delivery system. Overall, the patent application presents a novel approach to drug delivery using fusosomes, highlighting their potential in precision medicine and targeted therapy.
