(A) Experimental design: C57BL/6 mice were immunized with MOG35–35 to induce EAE at day −25, −15, or −5 prior to either sham or CLP surgery, and age-matched nonimmunized (non-EAE) underwent CLP surgery at the same time. Mortality was monitored in all cohorts. (B) EAE clinical scores of mice that were induced for EAE at −25, −15, −5 prior to either sham or sepsis surgery. (C) Kaplan–Meier survival curves of day −25 EAE mice that underwent sham surgery (black circle), non-EAE mice that underwent sepsis surgery (red circle with black outline), and day −25 (red circle with red outline), day −15 (red semicircle), and day −5 (white circle with red outline) EAE mice that underwent CLP. Data are cumulative of two independent experiments with 5–31 mice per group. Error bars represent SEM. *p < 0.05.
