A) Schematic of EED protocol, antibiotic treatment and
vaccination regime. Mice on ISO or EED protocols were treated with antibiotics
for 3 weeks, ending on day 49 when they are orally vaccinated.
B) Numbers of LTA166-176:I-Ab
specific CD4+ T cells isolated from the siLP and MLN of mice
vaccinated after 3 weeks of treatment with (shaded bars) or without (clear bars)
antibiotics. Data points represent a single mouse. Data are pooled from 2
independent experiments (n=3/experiment). Graphs show the mean ±SEM.
Statistics calculated by one-way ANOVA (*p ≤ 0.05; **p ≤ 0.01;
