Absolutely! There is an abundance of evidence describing the shuttling of microRNA and messenger RNA through microvesicles and/or exosomes. I am most familiar with microRNAs, so my answer will focus on those. The most well characterized model system of exosome-mediated microRNA transfer in the immune synapse between dendritic cells and T-cells (see attached paper by Nolte-‘t Hoen et. al.). There is also significant evidence of both exosomal transfer of microRNAs in several cancer-related mechanisms (see attached papers by Tadokoro et. al. and Hood et. al.). Finally, some recent evidence has shown that microRNAs can be selectively packaged into exosomes for secretion through the recognition of a sumoylated RNA-binding protein to a specific microRNA sequence (see attached paper by Villarroya-Beltri et. al.).
Sorry for the long answer, but I hope it helps. The additional attachments will be added as separate comments.
Thanks for all the information. I am sorry missed the early replies. My focus is on malaria and this does further the possibilities of host -parasite modulation in either direction. Could extend to many other similar infections as well. Would certainly have implications for preventives being investigated.
