The aim is to understand how self-reactive B cells evolve and contribute to autoantibody responses in lupus.
Utilized the 564Igi lupus model to investigate autoreactive B cell dynamics.
Employed mixed bone marrow chimera and adoptive transfer approaches.
Analyzed participation of wild-type B cells in germinal center and extrafollicular pathways.
Wild-type B cells were recruited into autoreactive niches, engaging in autoantibody responses.
Autoreactive B cells evolved through a dynamic process of epitope spreading.
B cell clones displayed sustained activation, differentiation, and diversification within autoimmune environments.
