The epigenetic processes that regulate antibody-secreting plasma cells are not well understood. Here, analysis of plasma cell differentiation revealed DNA hypomethylation of 10% of CpG loci that were overrepresented at enhancers. Inhibition of DNA methylation enhanced plasma cell commitment in a cell-division-dependent manner. Analysis of B cells differentiating in vivo stratified by cell division revealed a fivefold increase in mRNA transcription coupled to DNA hypomethylation. Demethylation occurred first at binding motifs for the transcription factors NF-κB and AP-1 and later at those for the transcription factors IRF and Oct-2 and was coincident with activation and differentiation gene-expression programs in a cell-division-dependent manner. These data provide mechanistic insight into cell-division-coupled transcriptional and epigenetic reprogramming and suggest that DNA hypomethylation reflects the cis-regulatory history of plasma cell differentiation.

Enzyme digested and mock digested samples are run adjacent on the agarose gel and indicated by a “+” and “-“ at the bottom of the gel image, respectively. Biological replicates are indicated on top. B220intCD138+ Plasmablasts and B220loCD138+ plasma cells were obtained from the same mice. Six mice were used in this experiment.
Plasmablast and plasma cell DML near Cd86, Irf4, Prdm1, and Il10 were validated in naïve B cells (nB), GL7+ activated B cells (aB), B220intCD138+ splenic plasmablasts (PB), B220loCD138+ splenic plasma cells (PC), B220intCD138+ bone marrow cells (BMPB), and B220loCD138+ bone marrow cells (BMPC).
