Xu and colleagues use single-cell transcriptomic analyses to uncover distinct expression dynamics of metabolic programs in germinal center B cells. Coupled analysis of transcriptional states and Igh variable sequences revealed that OXPHOS metabolism is enhanced in GC B cells undergoing positive selection. Their findings suggest BCR signaling tunes GC B cell metabolism to accelerate the cell cycle of positively selected GC B cells.
