Immunization with two TLR agonists induces persistent germinal centers and long-lived antibody-forming cells in draining lymph nodes. C57BL/6 mice were immunized with OVA encapsulated in nanoparticles with TLR-4 agonist (MPL) and TLR-7 agonist (R837) plus antigen. (A) Antibody titers 4 weeks post-prime. (B) Germinal centers (GCs) were counted in draining lymph node (LN) sections over time. (C) ELISPOT assay quantification of antibody-secreting cells in lymph nodes over time.
