Figure Lengend Snippet: a Experimental layout for ( b , c ). b , c Absolute number of MHC-II + CD11c + DCs (CD45 + Gr1 − CD19 − CD3e − pre-gates) in tumor ( b ) and spleen ( b ) of A20.GL tumor-bearing mice treated as outlined in ( a ). Each dot represents one mouse (Day 1, 2: n = 3/group; Day 3: n = 6/group; Day 7: n = 6–7/group). Data are plotted as mean ± SD. p -values were obtained from an unpaired two-tailed Student’s t test. d A20.GL tumor-bearing wild-type (WT) or Cd40 −/− mice received 3 × 10 6 CAR T cells intravenously (i.v.). The percentage of MHC-II hi CD11c int migratory DCs (migDC) in tumor-draining lymph-nodes (tdLNs) was analyzed on day 7. Data are plotted as mean ± SD and pooled from two independent experiments (WT: n = 6/group; Cd40 −/− : n = 4/group). p -values were determined by two-way ANOVA test. e A20.GL tumor-bearing mice received 3 × 10 6 CAR T cells i.v. and CCR7 surface expression was analyzed on day 7 on CD11b − CD103 − double-negative (DN) (orange), CD11b − CD103 + cDC1 (green), and CD11b + CD103 + cDC2 (blue) populations in the tumor. Gray histogram, flow minus one. f A20.GL tumor-bearing mice received 3 × 10 6 CAR T cells i.v. and the percentage of CD11b − CD103 − DN (orange), CD11b − CD103 + cDC1 (green), and CD11b + CD103 + cDC2 (blue) populations in the tumor was analyzed on day 7. g A20.GL tumor-bearing mice received 3 × 10 6 CAR T cells i.v. and the percentage of CD11b − CD8α − DN (orange), CD11b − CD8α + cDC1 (green), and CD11b + CD8α − cDC2 (blue) populations in the spleen was analyzed on day 7. h The cDC1/cDC2 ratio in A20.GL tumor-bearing WT mice is plotted in the tumor and spleen of mice treated in ( f , g ). i The cDC1/cDC2 ratio in A20.GL tumor-bearing Cd40 −/− mice is plotted on day 7 after receiving 3 × 10 6 CAR T cells. Data in ( e – i ) is plotted as mean ± SD and pooled from two independent experiments. Each dot represents one mouse ( e – h , n = 7/group; i , n = 4/group). p -values were obtained from an unpaired two-tailed Student’s t test. ns, non-significant; i.v. intravenous; resDC, resident DC.
