B cell progression through the GC is tightly regulated and the molecular determinants that modulate GC B cell proliferation and survival are still under investigation. Here, we use a conditional deletion mouse model to demonstrate that bromodomain PHD finger transcription factor (BPTF), a subunit of the nucleosome remodeling factor (NURF) chromatin remodeling complex, is required for robust GC B cell responses following vaccination. In GC B cells, Bptf loss induces a stress-like transcriptional profile and a shift towards PC identity-defining transcriptional programing, although this does not lead to accumulation of functional PCs. Rather, we show that BPTF-deficient GC B cells are prone to cell death. Cumulatively, our data demonstrate that BPTF is necessary for GC B cell maintenance and robust antigen-specific B cell responses.</description><dates><publication>2026/04/17</publication></dates><accession>GSE327666</accession><cross_references><GSM>GSM9662925</GSM><GSM>GSM9662926</GSM><GSM>GSM9662923</GSM><GSM>GSM9662924</GSM><GSM>GSM9662929</GSM><GSM>GSM9662927</GSM><GSM>GSM9662928</GSM><GSM>GSM9662932</GSM><GSM>GSM9662933</GSM><GSM>GSM9662922</GSM><GSM>GSM9662930</GSM><GSM>GSM9662931</GSM><GPL>34290</GPL><GSE>327666</GSE><taxon>Mus musculus</taxon></cross_references></HashMap>
