Antigen-specific production of immune interferon by T Cells lines

Continuous cultures of T cells reactive to the hapten 4-ethoxymethylene-2-phenyloxazolone were tested for interferon production after antigenic stimulation in vitro. Induction of interferon was antigen-specific and also restricted by the I region of the major histocompatibility complex. Kinetics of antigen induced interferon production were different from those reported for mitogen induced synthesis.
