Little is known about the earliest transcriptomic events in plasma cell differentiation. Indeed, activation of UPR-affiliated gene expression is seen in in-vitro plasma cell differentiation prior to Blimp1 upregulation and in the absence of Xbp1 as we show in linked companion series. In this study, Blimp1 reporter mice were immunized with the T-independent antigen NP-LPS four days prior to spleen harvest and nave B cells, NP-binding activated B cells and NP-binding plasma cells were analyzed by bulk RNA-seq. Here we report the activation of ER remodeling gene expression in antigen-specific activated B cells in-vivo prior to upregulation of Blimp1 transcription.
