Host range conversion of murine leukemia virus resulting from recombination with endogenous virus

Host range conversion of murine leukemia virus resulting from recombination with endogenous virus Ecotropic murine leukemia viruses (MuLVs) are classified into B-, N-, or NB-tropic MuLV by their host range determined by the Fv-1 gene product. B-tropic MuLV is restricted in N-type mouse cells (Fv-1 n/n ) and N-tropic MuLV is restricted in B-type mouse cells (FV-1 b/b ). Although forced passages in a restrictive host grant a wider host range (NB-tropism), we show here a host range conversion from B to N tropism. The conversion was most likely a result of recombination between the exogenously infected B-tropic MuLV and an endogenously expressed N-tropic MuLV in a C57BL/6 mouse cell line, YH-7. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

Abstract

Ecotropic murine leukemia viruses (MuLVs) are classified into B-, N-, or NB-tropic MuLV by their host range determined by the Fv-1 gene product. B-tropic MuLV is restricted in N-type mouse cells (Fv-1 n/n ) and N-tropic MuLV is restricted in B-type mouse cells (FV-1 b/b ). Although forced passages in a restrictive host grant a wider host range (NB-tropism), we show here a host range conversion from B to N tropism. The conversion was most likely a result of recombination between the exogenously infected B-tropic MuLV and an endogenously expressed N-tropic MuLV in a C57BL/6 mouse cell line, YH-7.
