Research Abstract

We found that the deposition of histone variant was markedly decreased during B cell differentiation into plasma cells. We also confirmed by chip-seq and mRNA-seq that the histone variant bind to the regulatory element of genes that will be expressed during differentiation. Furthermore, constitutive expression of his ton variant in B cells resulted in the inhibition of plasma cell generation. These findings suggest that B cel differentiation is controlled by dynamic change of chromatin structure.
