AAK1 and infection: To determine whether AAK1 kinase activity plays a role in RABV infection, HEK-293 cells, SK cells, and mouse primary neuron (mPN) cells were pretreated with different concentrations of sunitinib or DMSO for 1 h at 37 °C before infection with ERA-mCherry at a multiplicity of infection (MOI) of 0.01.
