In a T-cell dependent development pathway, naïve follicular B cells are activated by antigen presenting follicular B helper T cells (TFH) during the initial infection, or primary immune response. Naïve B cells circulate through follicles in secondary lymphoid organs (i.e. spleen and lymph nodes) where they can be activated by a floating foreign peptide brought in through the lymph or by antigen presented by antigen presenting cells (APCs) such as dendritic cells (DCs).
