Abstract
Transfer of allergic encephalomyelitis has been accomplished by injection of lymph node cells, obtained from donor rats sensitized to spinal cord, into recipient rats pretreated neonatally with normal rat spleen cells. Transfer of the disease may be achieved most frequently when the recipients are pretreated with spleen cells of the prospective lymph node cell donors. These transfers are attributed to the use of recipients which have acquired immunological tolerance to donor lymph node cells, as a result of the spleen cell pretreatment, and in which, therefore, the donor cells can survive and function longer after transfer.
