Many viruses use the host trafficking system at a variety of their replication steps. Measles virus (MV) possesses a nonsegmented negative-strand RNA genome that encodes three components of the ribonucleoprotein (RNP) complex (N, P, and L), two surface glycoproteins, a matrix protein, and two nonstructural proteins. A subset of immune cells and polarized epithelial cells are in vivo targets of MV, and MV is selectively released from the apical membrane of polarized epithelial cells. However, the molecular mechanisms for the apical release of MV remain largely unknown. In the present study, the localization and trafficking mechanisms of the RNP complex of MV were analyzed in detail using recombinant MVs expressing fluorescent protein-tagged L proteins. Live cell imaging analyses demonstrated that the MV RNP complex was transported in a manner dependent on the microtubule network and together with Rab11A-containing recycling endosomes. The RNP complex was accumulated at the apical membrane and the apical recycling compartment. The accumulation and shedding of infectious virions were severely impaired by expression of a dominant negative form of Rab11A. On the other hand, recycling endosome-mediated RNP transport was totally dispensable for virus production in nonpolarized cells. These data provide the first demonstration of the regulated intracellular trafficking events of the MV RNP complex that define the directional viral release from polarized epithelial cells.
