Figure Lengend Snippet: A) NanoString-based analysis of Toll-like receptor ( Tlr ) and MyD88 expression in the brainstem of 45-day old control and Ndufs4 (-/-) mice (see Methods ). Black – Ndufs4 (Ctl), Red – Ndufs4 (-/-) (see Methods ). p-values reflect multiple testing corrected (Holm-Šídák method) pairwise t-tests. *p<0.05, ns and those not shown – not significant. B ) Taqman probe-based qPCR analysis of Tlr7, Tlr9 , and MyD88 expression in 50-day old control and Ndufs4 (-/-) mouse brainstem samples. Normalized to actin, included in each reaction. Black – Ndufs4 (Ctl), Red – Ndufs4 (-/-) (see Methods ). Relative expression calculated using relative standard curve approach. *p<0.05, ns – not significant, by Holm-Šídák method multiple-testing corrected pairwise t-tests with Welch’s correction (no assumption regarding standard deviation).

Figure Lengend Snippet: A) Impact of enrofloxacin and MyD88 disruption on survival in Nduf4 (-/-) mice (see Methods , introduction). P-values shown indicate pairwise log-rank test comparisons between curves indicated - **p=0.0087, *p<0.013. n’s as indicated. B) Cause of death in mice from A). FDIC – found dead in cage, cause of death unknown. C) Summary of findings. Enrofloxacin treatment modestly accelerates disease progression in the Ndufs4 (-/-) model, while loss of MyD88 modestly slows disease progression and extends survival.

Figure Lengend Snippet: A Study schedule. Mice were injected IM with Ag mixed with A-910823 on days 0 and 14 ( n = 4–10/group), using Myd88 ( B ), Il1r1 ( C ), and Il1rn KO mice ( D ), as well as Myd88 flox/flox (f/f) and Cd11c cre ( E ) or LysM cre mice ( F ). B – F Serum titers of neutralizing antibodies against SARS-CoV-2 on day 28. Bars represent geometric mean titer (GMT); error bars indicate 95% confidence intervals; circles represent neutralizing antibody titers in individual mice. Percentages of T follicular helper (Tfh; PD1 + CXCR5 + ) cells in TCRb + CD4 + cells and percentages of germinal center B (GCB; FAS + GL7 + ) cells in CD19 + cells in draining LNs on day 28. Bars represent means; error bars indicate standard error of the mean; circles represent percentages of Tfh and GCB cells in individual mice. Injection-site swelling scores on day 15. Bars represent means; error bars indicate standard error of the mean; circles represent swelling scores in individual mice. Average body temperature was assessed on Day 12 (08:00–19:59) and on Day 15 (08:00–19:59). Vaccination at day 14 was performed at 18:00. Bars represent means; error bars indicate standard error of the mean. The data were derived from independent experiments: (1) Neutralizing titer/Tfh/GCB measured in the same cohort, (2) Swelling measured in an independent cohort, and (3) Fever measured in an independent cohort. Statistical significance determined using two-tailed Student’s t -test for two-group comparisons or two-way ANOVA. ns, P ≥ 0.05, * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001.
