Selection and characterization of a BHK-21 cell line resistant to infection by Theiler's murine encephalomyelitis virus due to a block in virus attachment and entry.
A clonal population of BHK-21 cells resistant to infection with the low-neurovirulence BeAn strain of Theiler's murine encephalomyelitis virus (TMEV) was derived after four cycles of infection and characterized. These cells were resistant to both low- and high-neurovirulence TMEV strains due to a block in virus attachment and entry and not in virus replication, since transfection of these cells with TMEV RNA to bypass the entry step(s) induced virus replication and assembly. The resistance to infection was stable for more than a year, suggesting that it is a heritable property arising from a mutation in the susceptible parent BHK-21 population. This cell line is being used to identify a receptor for TMEV.
