Laboratory-attenuated RABV and wt RABV trans-complemented with G from laboratory-attenuated virus can activate DCs in an IPS-1-dependent manner. (A) Flow-cytometric analysis of the number of CD86-, CD80-, and MHC-II-positive DCs derived from IPS-1 knockout or wild-type mice that were mock treated, infected with CVS-B2c, DRV-Mexico, B2c(DRV-P), B2c(DRV-G), or DRV(B2cG), or treated with LPS or poly(I·C).
