Figure Lengend Snippet: a Timeline of in vivo experiments. Consistent results were obtained in two independent experiments ( n = 5 mice). b Representative bioluminescence images of mice subjected to different treatments. Colors represent the luminescence intensity (red, highest; blue, lowest). c , d Quantification of the average radiance (p/s/cm /sr) of the luminescence, related to APRIL- ( c ) and BAFF-( d )-based CAR-T-cell therapy. Two-way ANOVA multiple comparisons in Dunnett correction were used to assess significance. e Evaluation of serum inflammatory cytokine release by ELISA 24 h after CAR-T-cell infusion. One-way ANOVA multiple comparisons in Tukey correction were used to assess significance. f , g Survival curves of the mice subjected to the indicated treatments. Survival curves were compared using the log-rank (Mantel‒Cox) test. h Timeline of in vivo experiments. Consistent results were obtained in two independent experiments ( n = 5 mice). i Representative bioluminescence images of mice subjected to different treatments. Colors represent the luminescence intensity (red, highest; blue, lowest). j Quantification of the average radiance (p/s/cm /sr) of the luminescence. Two-way ANOVA multiple comparisons in Dunnett correction were used to assess significance, comparing 9E10-IgG4m CAR-T (with Myc-BAFF) and CD19/CD22 CAR-T. k Evaluation of serum inflammatory cytokine release by ELISA 24 h after CAR-T-cell infusion. One-way ANOVA multiple comparisons in Dunnett correction were used to assess significance. l Assessment of the presence of persistent human CD3 + (hCD3 + ) T cells in peripheral blood by flow cytometry over a 3-week follow-up period. Two-way ANOVA multiple comparisons in Dunnett correction were used to assess significance, comparing 9E10-IgG4m CAR-T (with Myc-BAFF) with BAFF-CAR-T at each time point. m Survival curves of mice subjected to the indicated treatments, compared using the log-rank (Mantel‒Cox) test. All n represents biological replicates from different mice. Data in this figure are representative of one of two independent experiments. Error bars represent mean ± SEM. NS indicates not significant. Source data are provided in the Source Data file.
