Because host or viral RNA or other genetic material packaged into the tegument would also be expected to be damaged during UV inactivation, we therefore have not yet eliminated the possibility that infection of IC-21 cells may stimulate SOCS1 and/or SOCS3 by one or more viral or host transcripts that are packaged into the tegument of SG-MCMV. This evidence concerns the gene SOCS1 and infection.
