title: An autoreactive T hybridoma expressing nonspecific helper activity.
abstract: Two functional T hybridomas were prepared by fusing BW5147 with ovalbumin (OVA)-primed splenic T blast cells. One was OVA specific for helper function requiring concanavalin A supernatant (CAS) for activity while the other, termed autoreactive, was nonspecific for helper-augmenting activity. Both required H-2d presenter cells for interleukin 2 (IL-2) production. The autoreactive clone showed helper activity only in the presence of suboptimal numbers of antigen (Ag)-primed T cells. Both T hybridomas were Lyt 1+2+ and Thy 1+. Cells produced from such fusions should provide a useful instrument not only in dissecting the T-cell regulatory mechanism, but also in isolating and characterizing self-recognition structures.
