Transplantation of normal bone marrow from C3H/HeN nu/nu (H-2k) mice into young MRL/MP-lpr/lpr (MRL/l; H-2k) mice (< 1.5 mo.) prevented the development of autoimmune diseases and characteristic thymic abnormalities in the recipient mice. When female MRL/1 (> 2 mo.) or male BXSB (H-2b) mice (9 mo.) with autoimmune diseases and lymphadenopathy were lethally irradiated and then reconstituted with allogeneic bone marrow cells from young BALB/c nu/nu (H-2d) mice (< 2 mo.), the recipients survived for > 3 mo. after the bone marrow transplantation and showed no graft-vs.-host reaction. Histopathological study revealed that lymphadenopathy disappeared and that all evidence of autoimmune disease either was prevented from developing or was completely corrected even after its development in such mice. All abnomal T-cell functions were restored to normal. The newly developed T cells were tolerant of both bone marrow donor-type (BALB/c) and host-type (MRL/l or BXSB) major histocompatibility complex (MHC) determinants. T-cell dysfunction in autoimmune-prone mice can be associated with both the involutionary changes that occur in the thymus of the autoimmune-prone mice and also to abnormalities that reside in the stem cells. Normal stem cells from BALB/c nu/nu donors can differentiate into normal functional T cells even in mice whose thymus had undergone considered involution, as in the case of BXSB or MRL/l mice in the present studies. Marrow transplantation may be a strategy ultimately to be considered as an approach to treatment of life-threatening autoimmune diseases in humans. T-cell dysfunction in autoimmune-prone mice previously attributed to involutionary changes that occur in the thymus of these mice may instead by attributed to abnormalities that basically reside in the stem cells of the autoimmune-prone mice.
