EIF2A and infection: To determine whether treatment of SHFV-infected cells with an exogenous SG inducer alters the phosphorylation levels of eIF2α, MA104 cells were either mock-infected or infected with SHFV (MOI of 0.1), and at various times post-infection, cells were treated with SA (2 mM) or DTT (2 mM) for 45 min and then harvested for WB analysis.
