A.SW mice sensitized with myelin oligodendrocyte glycoprotein (MOG)92–106 is an animal model for progressive multiple sclerosis (MS). We isolated MOG-reactive monoclonal antibodies that were immunoglobulin (Ig)M and polyreactive, similar to natural autoantibodies. Upon analysis of the variable (V) light chains and the diversity (D) and joining (J) regions of V heavy chains, we found they were identical to germ line Vκ19/28, Jκ5, DFL16.1e and JH4, respectively. The sequence of the VH region had 99.7% and 100% identity at the nucleotide and amino acid levels, respectively, compared with the germ line encoded antibody, P3, of the Q52 family. Although A strain mice have been reported to have an insertion in BAFF-R, the receptor for BAFF (B cell activation factor from the tumor necrosis factor family), which could explain our results, A.SW mice have no mutations in BAFF-R.
