As the progeny of germinal center B cells includes long-lived plasma cells, selection of autoreactive B cells can propagate long-lived … SpletShort-lived plasma cells typically arise in the red pulp of the spleen immediately after infection, whereas long-lived plasma cells arise weeks after antigen exposure and typically reside in specialized niches in the bone marrow. Both mouse and human plasma cells are commonly identified as CD19 - Syndecan-1/CD138 + cells.
