Abstract:
:Two models of murine graft-versus-host disease (GVHD) were studied with respect to autoantibody production and development of systemic lupus erythematosus (SLE) like disease. One model was induced by injection of (B10.A(4R) x B10.A(2R]F1 mice with parental (B10.A(4R] spleen and lymph node cells (groups I GVHD), the other by injection of (DBA/2 x C57/B16)F1 mice with DBA/2 cells (group II GVHD). Group I GVHD mice remained in a seemingly healthy condition and did not show any proteinuria, in spite of high titres of anti-nuclear antibodies including antibodies to dsDNA, anti-Sm and anti-ribosomal P protein antibodies. Measured levels of these autoantibodies as well as their isotypes were comparable with those found in MRL/lpr and NZB/W mice. Group II GVHD mice developed SLE-like disease signs, including severe proteinuria. At 4 months after induction of the GVHD, almost 50% of these mice had died. At the time nephritis was present, group II mice also produced anti-dsDNA and anti-nuclear antibodies of other (unknown) specificities, but no anti-Sm or anti-P. Furthermore, the incidence of these antibodies was lower than observed in group I GVHD, MRL/lpr or NZB/W mice. It is concluded that (high avidity) anti-dsDNA as well as anti-Sm and anti-P may be present in the circulation without giving rise to the development of nephritis.
