title: 'Lupus-prone' mice are susceptible to organ-specific autoimmune disease, experimental allergic encephalomyelitis.
abstract: Immunization with the multideterminant autoantigen myelin basic protein (MBP) causes experimental allergic encephalomyelitis (EAE), a T-cell-mediated autoimmune disease that serves as a model for multiple sclerosis (MS). MBP peptides Ac1-11 and p35-47 induce potent EAE in mice of the H-2u haplotype. T cells specific for Ac1-11 predominantly utilize one T-cell receptor (TCR) V beta gene segment, V beta 8.2. All T-cell clones and hybridomas analyzed, regardless of TCR V beta usage, utilize D beta 2 and J beta 2 elements. The NZW mouse strain (H-2z), which contributes to the spontaneous 'lupus-like' illness in (NZB x NZW)F1 mice, has a genomic deletion encompassing D beta 2 and J beta 2 gene segments. The NZW strain expresses class II (I-A and I-E) genes which share identical sequences with H-2u class II. We investigated whether these strains are susceptible to EAE induced with intact MBP and known encephalitogenic MBP peptides. In vitro analysis demonstrated that NZW antigen-presenting cells (APC) can present MBP and MBP peptide Ac1-11 to an encephalitogenic T-cell clone derived from an H-2u mouse, confirming the functional identity of NZW class-II (I-A) molecules with their respective H-2u class-II gene products. In vivo results demonstrated that NZW and (NZB x NZW)F1 mice are susceptible to EAE induced with intact MBP and Ac1-11. MBP p35-47 caused EAE in (NZB x NZW)F1 mice, which express alleles for both the normal (NZB) TCR beta-gene locus, and the abnormal (NZW) TCR beta-gene locus containing the J beta 2 deletion.(ABSTRACT TRUNCATED AT 250 WORDS)
