Abstract:
Background: Exosomes, one of the extracellular vesicles, are widely present in all biological
fluids and play an important role in intercellular communication. Due to their hydrophobic lipid bilayer
and aqueous hydrophilic core structure, they are considered a possible alternative to liposome drug delivery
systems. Not only do they protect the cargo like liposomes during delivery, but they are also less
toxic and better tolerated. However, due to the lack of sources and methods for obtaining enough
exosomes, the therapeutic application of exosomes as drug carriers is limited.
Methods: A literature search was performed using the ScienceDirect and PubMed electronic databases
to obtain information from published literature on milk exosomes related to drug delivery.
Results: Here, we briefly reviewed the current knowledge of exosomes, expounded the advantages of
milk-derived exosomes over other delivery vectors, including higher yield, the oral delivery characteristic
and additional therapeutic benefits. The purification and drug loading methods of milk exosomes, and
the current application of milk exosomes were also introduced.
Conclusion: The emergence of milk-derived exosomes is expected to break through the limitations of
exosomes as therapeutic carriers of drugs. We hope to raise awareness of the therapeutic potential of
milk-derived exosomes as a new drug delivery system.
