Abstract
Gene rearrangement in the immune system is always preceded by DNA demethylation and increased chromatin accessibility. Using a model system in which rearrangement of the endogenous immunoglobulin kappa locus is prevented, we demonstrate that these epigenetic and chromatin changes actually occur on one allele with a higher probability than the other. It may be this process that, together with feedback inhibition, serves as the basis for allelic exclusion.Mesh:
