Studies of experimental allergic encephalomyelitis by using encephalitogenic T cell lines and clones in euthymic and athymic mice.
The role of T-T cell interactions in the clinical course of acute experimental allergic encephalomyelitis (EAE) in mice was investigated. Myelin basic protein (MBP)-reactive and encephalitogenic T cell clones were established from long-term lines derived from susceptible strain SJL/J mice and resistant strain DDD/1 mice. The lines and clones from DDD/1 mice were obtained by immunization of congenitally athymic mice of DDD/1 origin, which had been reconstituted with syngeneic Lyt-2+-depleted splenic T cells. The clones derived from both strains bore surface phenotypes of Lyt-1+, 2- and L3T4+, and proliferated well in response to rat, rabbit, bovine, and guinea pig MBP in the presence of antigen-presenting cells with I-As. Passive EAE could be induced in syngeneic normal recipients by these clones as well as by the lines from which the clones were derived. The clinical features of the clone-induced EAE were essentially the same as those of the line-induced EAE. Furthermore, DDD/1 athymic recipients developed signs of acute EAE by the adoptive transfer of I-A-compatible syngeneic and allogeneic T cell clones, in which there was no significant difference in time of onset, maximum severity, or prognosis. These results indicate that the entire clinical course of acute EAE can be elicited by a single population of MBP-reactive T cells in the absence of the thymus and other populations of primed or unprimed T cells.[1]References
