Analysis of measles virus (MV) pathogenesis requires the development of an adequate small animal model of MV infection. In this study, permissivity to MV infection was compared in human and transgenic murine T lymphocytes, expressing different levels of the human MV receptor, CD46. Whereas MV binding and entry correlated with CD46 expression, higher levels of MV replication were always observed in human T lymphocytes. This suggests the existence of intracellular factors, acting posterior to virus entry, that could limit MV replication in murine lymphocytes and should be considered when creating new animal models of MV infection.
