| Research Abstract |
A therapy that inhibits only autoreactive lymphocytes is desirable for the treatment of systemic lupus erythematosus (SLE). We analyzed an SLE model ‘anti-DNA-antibody-knock-in mouse' to know how autoreactive B cells are regulated. The homozygotes' splenic B cells were significantly decreased, and their maturation was inhibited in the bone marrow. Homo's B cells tended to move to the marginal zone in their spleens. Homo's B cells showed low expression levels of IgM/IgD, and were supposed to be regulated by anergy. Further analyses will elucidate the pathophysiology of SLE.
