Figure-2. Exosome Structure.
Exosomes are capable of hosting a wide array of molecules including viruses, nucleic acid material (RNAs, DNA), and microRNAs depending on a variety of factors including the cell type or origin. Other factors influencing exosome content include pathological state of the host organism. The contents of exosomes can be transferred from the cell of origin to their target cells in local microenvironment or even at distant site that can possibly give rise to an exponential intercellular communication networks.
