Depletion of PLC is dependent on IL-12p40. (A) Enzyme-linked immunosorbent assay (ELISA)–based quantification of IL-12p40 (anti-p40 antibody [Ab]), IL-12 (anti-p70 Ab), and IL-23 (anti-p19 Ab) in sera from neonate and adult Eμ-ret mice at 3, 6, and 10 dpi (Mann-Whitney; n = 3-7). (B) Representative flow cytometry plots showing PLC in splenocytes of Eμ-ret pups after CMV infection in the presence of indicated neutralizing antibodies. (C) Cumulative results showing PLC burden in spleens of Eμ-ret pups infected along with p40, p19, and/or p70 neutralizing antibodies (1-way ANOVA; n = 4-11). (D) PLC numbers in spleens of PBS (Ctrl) or virus (CMV)-injected Rag1–/– (R/Rag, left panel), wild-type (R/wt), and NK-depleted wt (NK-dep, right panel) Eμ-ret pups at 10 dpi (Mann-Whitney; R/Rag1, n = 10 PBS and 10 MCMV; 1-way ANOVA; n = 8 PBS, 8 CMV, and 7 CMV + NK-depleted; pooled results from 3 independent experiments). All data presented as mean ± SEM (∗∗∗P < .001; ∗∗∗∗P < .0001). ns, not significant (nonsignificant comparisons in graphs A and C are not labeled).
