Résumé
C57BL/6J (B6) mice homozygous for the viable motheaten (mev) mutation are short-lived and display severe immunodeficiency, autoimmunity and inflammatory disease. B6 mice doubly homozygous for the nude (nu) and beige (bg) mutations (nubg mice) are also short-lived and immunodeficient. Nevertheless, grafts of mev lympho-hematopoietic cells increased life expectancy of nubg recipients. Such [mev --> nubg] chimeras did not develop any mev-like inflammatory pathology but showed autoimmunity features, particularly hyperglobulinemia which, unlike the mev one, was due to IgG rather than IgM. Serological studies of [mev IgHb --> nubg Igha] chimeras surprisingly revealed the exclusive host B-cell origin of the IgG2a overproduced by these chimeras. Yet, about half of such chimera serum IgM being IgMb, mev B cells had actually engrafted the nubg hosts. Together with the lack of transfer of the inflammatory pathology, this suggests that a non-mev environment might succeed acting as a regulator of some mev-induced dysfunctions.
