Clonal T cells fail to establish MxA-dependent antiviral status and allow selective viral replication.

Immunofluorescence analysis of VSV-infected PBMCs from patients with CTCL. (A) PBMCs were either treated with IFN-α (+IFN-α) or left untreated (untreated). (B) PBMCs were subsequently infected with VSV. Cells were harvested, fixed with acetone, and immunostained using antibodies specific for MxA and TCR Vβ6.7 (A) or VSV and TCR Vβ6.7 (B).
