Integrated single cell multiomic profiling and functional validation reveal distinct cellular routes to human plasma cell differentiation.
This study utilizes integrated single-cell multiomic profiling and functional validation to demonstrate that human B cells follow distinct differentiation routes to form plasma cells, with germinal center-independent pathways involving a transient MEF2C-driven CD30+ intermediate leading to CD44v9+ plasma cells, while germinal center-dependent pathways bypass this intermediate to generate CD44v9-negative plasma cells.
