Figure 7. Illustrates absence of TNP-OVA IgM antibody production after parasympathetic denervation of the spleen.

Figure 7

TNP-OVA IgM antibody production after i.v. injection of saline and TNP-OVA (dashed lines) or LPS and TNP-OVA(uninterrupted lines) in animals that sustained a parasympathetic denervation (red) or a sympathetic denervation (yellow) of the spleen or were sham operated (blue). Only parasympathetic denervation results in a nearly complete loss of antibody production with a similar response as if no LPS were given. (Two way ANOVA indicated difference between the sham and sympathetic denervation + LPS with the other groups without LPS and the parasympathetic denervated group with LPS p<0.01. Tukey post hoc test showed significant difference of day 7 and 10 of the sham and sympathetic denervation as compared to all other time points p<0.001.)
