In addition, another protein, moesin, has been shown to be linked with the susceptibility of human cells to MV infection. Murine cells are largely resistant to MV infection, although a number of cell types can be productively infected. As murine cells do not express CD46 an additional mechanism for the uptake of MV is likely. Murine cells possess a functional homologue of CD46 (Crry/p65) in addition to murine moesin, which has nucleotide and amino acid homology to human moesin. We report that anti-moesin monoclonal antibodies 119 and 38/87 reduce the number of infectious centres attributed to MV in murine cell lines NS20Y and L929, whereas polyclonal antisera specific for Crry/p65 and CD46 had no effect on MV infection of these cells. We suggest that moesin may be important in the non-CD46-mediated uptake of MV strain Edmonston by susceptible murine cell lines. * Author for correspondence.
