Tumour-secreted microvesicles carry bioactive molecules that can be transferred to recipient cells, impacting tumour progression. A study now shows that ARF6 drives miRNA loading into tumour microvesicles through interaction with pre-miRNA–Exportin-5 complexes, thus shedding light on specific cargo packaging mechanisms.
