Allelic exclusion and lymphocyte development. Lessons from transgenic mice.

Abstract

The generation of an appropriate, specific immune response to an antigen is a remarkable biological phenomenon. An examination of both allelic exclusion and lymphocyte development is critical for an understanding of this response. Over the last several years, studies using transgenic mice that carry immunoglobulin or T cell receptor transgenes have provided a more detailed understanding of the mechanism of allelic exclusion. Recently, these mice have been used to examine lymphocyte development. In the future, these mice may be used to study the role of lymphocytes in autoimmune diseases.
