Abstract

Transplantation of MHC-compatible, T-cell-depleted, bone marrow cells has successfully treated autoimmunities, immunodeficiencies, malignancies, and developmental deficiencies of the hematopoietic system. Recombinant inbred SCG/Kj mice develop spontaneous crescentic glomerulonephritis, systemic vasculitis, and a lymphoproliferative disorder early in life. To determine whether the precipitous autoimmune disease of SCG/Kj mice could be treated by bone marrow transplantation, 30 SCG/Kj mice were engrafted with T-cell-depleted, bone marrow (TCDM) from allogeneic, MHC-compatible, autoimmune-resistant C3H/He donors, and 30 SCG/Kj mice served as controls and received TCDM from syngeneic, SCG/Kj donors. A significant survival advantage was evident from SCG/Kj mice engrafted with C3H/He TCDM (p < 0.005), and an 89% extension of median survival compared to recipients of SCG/Kj TCDM. Within 28 weeks post-transplantation, 62% of mice engrafted with SCG/Kj TCDM had died with clinical signs of fatal crescentic glomerulonephritis. This result compared with only 10% of mice engrafted with C3H/He TCDM. Mice engrafted with SCG/Kj TCDM developed significantly greater titers of autoantibodies to ss-DNA, ds-DNA, and myeloperoxidase (ANCA) (p < 0.00...Continue Reading

Autoimmune Lymphoproliferative Syndrome

Autoimmune lymphoproliferative syndrome (ALPS) is a rare genetic disorder of abnormal lymphocyte survival caused by defective Fas mediated apoptosis. Discover the latest research on ALPS here.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
