| abstractText | MRL lpr/lpr mice suffer from a systemic lupus erythematosus-like autoimmune disease. The lpr mutation impairs the normal transcription of the fas message, the product of which mediates apoptosis and presumably the proper selection of T cells. We have found an early expansion of CD4+ T cells bearing a distinctive V beta 8.3-D beta 1.1-J beta 1.1 T cell receptor beta chain in the periphery of MRL lpr/lpr mice, which was not detected in MRL +/+ mice nor in the thymus of MRL lpr/lpr mice. Thus, since thymic selection is normal in MRL lpr/lpr mice, we propose that the lpr mutation results in defective negative selection at the periphery. |
