Graded expression of interferon regulatory factor-4 coordinates isotype switching with plasma cell differentiation.

Abstract

Molecular mechanisms underlying the coordination of isotype switching with plasma cell differentiation are poorly understood. We show that interferon regulatory factor-4 (IRF-4) regulates both processes by controlling the expression of the Aicda and Prdm1 genes, which encode AID and Blimp-1, respectively. Genome-wide analysis demonstrated that Irf4(-/-) B… (More)
