Thus, some of the possible explanations for axonal dysfunction causes by the autoantibodies are: (1) anti‐SSA/SSB exerts its neuropathic effect by causing vasculitis that affects vasa vasorum and peripheral nervous system, or (2) anti‐SSA/SSB causes axonal degeneration and myelinated fiber loss due to nodal/internodal expression of SSA/SSB antigens induced under certain circumstances. This evidence concerns the gene SSB and vasculitis.
