We analysed the production of transforming growth factor β (TGF-β) during a cytomegalovirus (CMV) infection in a rat model system. Splenocytes from immunocompetent rats infected with rat CMV (RCMV) released increased amounts of TGF-β 1. TGF- β production was also evident in RCMV-infected radiation-immunosuppressed rats; their sera inhibited the interleukin 2-induced proliferation of T cells, which could be restored by anti-TGF-β anti bodies. In addition, TGF-β production could be visualized immunohistologically in the lungs, spleen, liver and bone marrow of radiation-immunosuppressed infected rats. The virus directly induced this cytokine since TGF-β was produced upon RCMV infection in vitro. The induction of TGF-β production may contribute to immunosuppression during CMV infection.
