Abstract:
Receptor editing and receptor revision are the two mechanisms of antibody diversity that result in either complete V-gene replacement or the formation of hybrid V genes. We do not yet understand how this process unfolds, because they are rare and difficult to study in vivo. In this study, we describe a family of VH4-34:VH4-61 hybrids isolated from a human B-cell chimeric non-obese diabetic/severe combined immunodeficient mouse. The observation of hybrid immunoglobulin sequences in human B cells that developed in this model system makes it useful for the study of this mechanism of diversification and tolerance.

Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
