In
vivo immunomodulation improves antibody titers
in an influenza model and reduces systemic cytokines in a Typhim Vi
vaccination. (A) Schematic of in vivo study timeline.
(B) Structure of additional modulators. (C) Typhim Vi + modulator
systemic TNF-α levels 1 h after vaccination with vaccine, vaccine
+ modulator, and vehicle (N = 5). Statistical analyses
between agonist + modulator groups and agonist alone were performed
by a one-way ANOVA test *P < 0.05, **P < 0.01. (D) Fluzone 2021–2022 + modulator antigen specific
serum IgG antibody levels, day 49, n = 5. Statistical
analyses between Fluzone and Fluzone + PME-564 were performed by a
one way ANOVA test. *P < 0.05, **P < 0.01, ***P < 0.001, ****P <.0001.
