Induction of tolerance to self-antigens using genetically modified bone marrow cells

Expert Opin Biol Ther. 2004 Jul;4(7):1007-14. doi: 10.1517/14712598.4.7.1007.

Abstract

The challenge of finding a lasting cure for autoimmune disease(s) has not been met. Although the use of systemic anti-inflammatory agents still dominates the treatment of these diseases, there is a push towards developing novel and more specific strategies. In addressing autoimmunity, there is the intrinsic need to understand the mechanisms that lead to the development and maintenance of immunological tolerance to self-antigens. Experimental evidence has shown that directed antigen expression in the thymus can induce immunological tolerance to that antigen. This forms the cornerstone of one strategy directed towards the cure of autoimmunity. In this strategy, individuals with autoimmune disease are transplanted with bone marrow stem cells that have been genetically modified and in this way allow expression of the self-antigen in the thymus.
