Abstract
Adoptive transfer of experimental allergic encephalomyelitis (EAE) was carried out in Lewis rats using splenic lymphocytes incubated in vitro with either concanavalin A (Con A) or myelin basic protein (MBP). Requirements were established for sensitization of donors, culture conditions, numbers of transferred cells, and incubation period of EAE in recipients. These were strikingly similar whether Con A or MBP was used. In addition, cellular proliferation in vitro was not required in either system, but proliferation after transfer to the recipient was essential for the development of clinical signs and histological lesions. These methods have potential value for analyzing mechanisms of immune induction in this classic model of autoimmune disease.
