Abstract
Thoracic duct lymphocytes (TDL) from Lewis rats immunized 9-10 days previously with basic protein in complete Freund's adjuvant (BP-CFA) failed to induce experimental allergic encephalomyelitis (EAE) in syngeneic recipients. This contrasts with the successful transfer of EAE by lymph node cell suspensions from donors immunized 9 days previously with BP-CFA. Only minor EAE was induced passively by TDL from rats immunized 11-12 days before with BP-CFA. TDL collected 9-20 days after BP-CFA immunization, however, were successful in transferring specific suppression of EAE tested by the lack of disease in the recipients immunized actively with BP-CFA 1 week after the TDL transfer. The data indicate that the thoracic duct contains specific suppressor cells shortly before, during and after the development of clinical EAE.
