AB Both heterogeneity and restricted heterogeneity of the encephalitogenic
myelin basic protein (MBP) peptide-specific T cell receptors (TCRs) were
demonstrated in inbred animals depending on the strain-specific genetic
characteristics, the stage of the disease, the compartment of the
lymphocytes obtained and the methodology used. Nevertheless, the similar
features of some MBP-specific TCRs demonstrated across species suggest
that conservation of these autoantigen-specific molecules undoubtedly
exists, even though the degree of this conservation is controversial.
However, the unequivocal heterogeneity of the immune response directed
at one of the most important myelin constituents, proteolipid
lipoprotein (PLP), which occurs either as a primary or a secondary event
during experimental allergic encephalomyelitis (EAE), indicates the
complexity of the in vivo situation. Intramolecular and intermolecular
spreading of antigen specificity during the course of the disease
indicates that a TCR directed therapy may not be the choice of
intervention in established disease even in individual strains of
laboratory animals with restricted heterogeneity of the primary
MBP-specific response. Studying the sequence of events, the recruited
regulatory cells and cytokines, and the stromal factors controlling
persistence or death of activated, memory cells in the tissue lesion,
may reveal new therapeutic modalities with more universal
applicabilities.
