via EVs. For example, the HIV co-receptors CCR5 and CXCR4 could be transferred from an HIV-susceptible cell to a refractory cell by "microparticles," rendering the recipient cell susceptible to infection.

Beginning in 2006, several laboratories reported that EVs contain nucleic acids and have the ability to transfer them from cell to cell. Nucleic acids including DNAs and RNAs were even found to be functional in the recipient cell. Whether carrying
