Figure 3. NKT Cells Are Required for Colonic Inflammation Induced by Frag-oz.
(A) Quantitative scoring for colitis after intra-rectal administration of 1% TMO or EtOH (50% v/v) vehicle in WT or CD1d-deficient (KO) littermates (n = 8). **p < 0.01 (Student’s t test).
(B) Quantification of IL-13 and IFN-γ production in overnatant of colon explants 2 days after intra-rectal administration of 1% TMO or EtOH (50% v/v) vehicle (n = 6). **p < 0.01 (Student’s t test).
(C) Weight change after intra-rectal administration of 1% Frag-oz or EtOH (50% v/v) vehicle in GF or SPF animals (n = 8). **p < 0.01, ***p < 0.001 (Mann-Whitney U test).
(D and E) Quantification of (D) Mttp and (E) Cyp1a1 transcripts (normalized to β-actin) from mucosal scraping 2 days after intra-rectal administration of 1% Frag-oz or EtOH (50% v/v) vehicle (n = 4). **p < 0.01, (Student’s t test)
(F) Quantitative scoring for colitis after intra-rectal administration of 1% TMO or EtOH (50% v/v) vehicle in GF or SPF animals (n = 8–9). **p < 0.01, p < 0.001 (Student’s t test).
