Abstract
We analysed the production of transforming growth factor beta (TGF- beta) during a cytomegalovirus (CMV) infection in a rat model system. Splenocytes from immunocompetent rats infected with rat CMV (RCMV) released increased amounts of TGF-beta1. TGF-beta production was also evident in RCMV-infected radiation-immunosuppressed rats; their sera inhibited the interleukin 2-induced
