AbstractEncapsulation of microRNAs in exosomes confers protection against degradation and a vehicle for shuttling of microRNAs between cells and tissues, and cellular uptake by endocytosis. Exosomes can be found in foods including milk. Humans absorb cow's milk exosomes and deliver the microRNA cargo to peripheral tissues, consistent with gene regulation by dietary nucleic acids across species boundaries.

MicroRNAs (miRNAs) can be synthesized endogenously and cause gene repression. Encapsulation of miRNAs in exosomes confers protection against degradation and a vehicle for shuttling between cells and tissues, and cellular uptake by endocytosis. Exosomes can be found in biological fluids and foods including milk. Evidence suggests that humans absorb cow’s milk exosomes and deliver the microRNA cargo to peripheral tissues, consistent with gene regulation by nucleic acids across species boundaries.
