In vivo immunomodulation improves
adjuvants in
a model ovalbumin vaccination. (A) Schematic of in vivo study timeline. (B) Additional modulators studied in vivo and their structures. (C) Agonist + PME-564 serum anti-OVA IgG antibody
levels, day 49, n = 4. Statistical analyses between
agonist and agonist + PME-564 were performed by an unpaired t test. (D) Systemic TNF-α levels 1 h after vaccination
with agonist, agonist + modulator, and vehicle (N = 4) for R848 (TLR7/8) and CpG (TLR9). Statistical analyses between
agonist + modulator groups and agonist alone were performed by a one-way
ANOVA test *P < 0.05, **P <
0.01, ***P < 0.001.
