TRAF3 and infection: Interestingly, upon SeV infection or stimulation with Poly(I:C), TRAF3 recruitment to TFG-containing immunocomplexes was further increased compared to that in control cells, plateauing at 4h for poly(I:C) transfection and increasing between 8 to 24 h post infection with SeV (Fig 3A and S3A Fig).
