Plasma cell differentiation requires silencing of B cell transcription, while it
establishes antibody-secretory function and long-term survival. The transcription
factors Blimp-1 and IRF4 are essential for the generation of plasma cells;
however, their function in mature plasma cells has remained elusive. We found
that while IRF4 was essential for the survival of plasma cells, Blimp-1 was
dispensable for this. Blimp-1-deficient plasma cells retained their
transcriptional identity but lost the ability to secrete antibody. Blimp-1
regulated many components of the unfolded protein response (UPR), including XBP-1
and ATF6. The overlap in the functions of Blimp-1 and XBP-1 was restricted to
that response, with Blimp-1 uniquely regulating activity of the kinase mTOR and
the size of plasma cells. Thus, Blimp-1 was required for the unique physiological
ability of plasma cells that enables the secretion of protective antibody.
