Figure 3. Priming protein immunization generates massive GC responses.
Analysis of GC LN cells from three groups of RMs: 1) unimmunized (‘none’); 2) injected with only PLGA(MPL+R848) (‘adjuvant only’); 3) immunized with either BG505 SOSIP.v5.2 + PLGA(MPL+R848) or BG505 SOSIP.v5.2 + Iscomatrix (‘adjuvant + BG505 SOSIP’).
A. GC Tfh cells, as % of CD4+ T cells.
B. GC B cells, as % of CD20+ B cells.
C. Correlation of GC B cell and GC Tfh frequencies in draining LNs after the 1st immunization.
