Allelic exclusion of immunoglobulin genes: models and mechanisms

Summary: The allelic exclusion of immunoglobulin (Ig) genes is one of the most evolutionarily conserved features of the adaptive immune system and underlies the monospecificity of B cells. While much has been learned about how Ig allelic exclusion is established during B‐cell development, the relevance of monospecificity to B‐cell function remains enigmatic. Here, we review the theoretical models that have been proposed to explain the...
