  • Publication number: 20060204495
    Abstract: Cross-reactive T cells recognizing both MBP93-105 and HHV-61-13 peptides represent a significant subset of T cells with some degree of TCR degeneracy. It appears that the recognition of the cross-reactive T cells has a less stringent requirement for the flanking residues of the two peptides. In contrast, these flanking residues are critical for the T cell recognition of mono-specific T cells. The association between HHV-6 and autoreactive immune responses to MBP indicates that cross-reactive T cells, peptides from the V-D-J region of the T cell receptor from autoreactive T cells, and antiviral agents may prevent or treat MS.

  • Publication number: 20050064483
    Abstract: The invention relates to gene expression profiling technology to quantitatively measure the expression profiles of genes selected based on their role in inflammation and their susceptibility to regulation by current multiple sclerosis (MS) treatment agents, beta-interferon (IFN) and glatiramer acetate (GA). The invention also provides an assay for detection of beta-IFN neutralizing antibody based on the blocking effect of serum antibodies on the known regulatory properties of beta-IFN on PBMC and evaluation of treatment responses in MS patients.
