Gene ontology analysis of signature exosomal miRNA targets revealed several signaling pathways that are known to be important in Kaposi's sarcoma-associated herpesvirus (KSHV) pathogenesis. Functional analysis of endothelial cells exposed to patient-derived exosomes demonstrated enhanced cell migration and IL-6 secretion. This suggests that exosomes derived from KSHV-associated malignancies are functional and contain a distinct subset of miRNAs. See Chugh et al.
