title: Neuroblastoma SH-SY5Y cell-derived exosomes stimulate dendrite-like outgrowths and modify the differentiation of A375 melanoma cells.
abstract: The identification of small vesicles released by many cell types as tools of intercellular communication is proposed. Here, we identify SH-SY5Y neuroblastoma-derived exosomes comprised of major histocompatibility complex II (MHC II), Hsp90 and flotillin-1. Our data also suggest that, when applied extracellularly, exosomes released from neuronal cells stimulate dendrite-like outgrowth and melanogenesis of A375 melanoma cells through the mitogen-activated protein kinase (MAP kinase), extracellular signal-regulated kinase 1 (ERK1) activation. These results suggest a modification of differentiation of melanocyte by the treatment of neuronal cell exosomes. Since exosomes from neuronal cells have the capacity to affect melanoma cells, they could be generally implicated in intercellular communication between different types of cells.
