  • Publication number: 20240042042
    Abstract: Provided herein, in some aspects, are delivery vehicles comprising a ceramide and an agent to be delivered attached to the ceramide. In some embodiments, the ceramide does not comprise a fatty acid (i.e., is a sphingosine). In some embodiments, the ceramide comprises a fatty acid. In some embodiments, the ceramide is a glycoceramide. In some embodiments, the agent is attached to the ceramide covalently (e.g., via a linker). In some embodiments, the agent to be delivered is a therapeutic agent. The ceramide is able to deliver the agent to a cell or to a cellular compartment, as well as across the musical barrier. In some embodiments, agents delivered using the ceramide described herein exhibit longer half-life, compared to agents delivered alone. Methods of delivering a therapeutic agent to a subject for treating a disease using the ceramide delivery vehicle are also provided.
