title: The fate of adoptively transferred quiescent encephalitogenic T cells in normal and antigen-tolerized mice.
abstract: Adoptive transfer of quiescent encephalitogenic T cells to normal syngeneic recipients was without clinical effect. RT-PCR was used to assess localization of an adoptively transferred quiescent encephalitogenic T cell clone in normal and antigen-unresponsive mice prior to or after challenge with neuroantigen/CFA. The T cell clone was not detectable in lymphoid tissues prior to challenge with neuroantigen; however, following challenge, the clone was found in the spleen, lymph nodes and spinal cord of both normal and antigen-tolerized mice. The latter animals remained clinically normal. Non-activated encephalitogenic T cells transferred to wild-type recipients pretreated i.p. with neuroantigen/IFA were rendered unresponsive. Transfer of the same T cells to alpha/beta T cell-deficient mice pretreated with neuroantigen/IFA resulted in spontaneous disease indicating that an intact alpha/beta T cell system was required for development of the unresponsive state.
