Identification of postentry restrictions to Mason-Pfizer monkey virus infection in New World monkey cells.

ABSTRACT: TRIM5alpha has been shown to be a major postentry determinant of the host range for gammaretroviruses and lentiviruses and, more recently, spumaviruses. However, the restrictive potential of TRIM5alpha against other retroviruses has been largely unexplored. We sought to determine whether or not Mason-Pfizer monkey virus (M-PMV), a prototype betaretrovirus isolated from rhesus macaques, was sensitive to restriction by TRIM5alpha. Cell lines from both Old World and New World primate species were screened for their susceptibility to infection by vesicular stomatitis virus G protein pseudotyped M-PMV. All of the cell lines tested that were established from Old World primates were found to be susceptible to M-PMV infection. However, fibroblasts established from three New World monkey species sp
