Figure 7. Pharmacologic intervention via inhibition of IL-1 signaling ameliorates ALD progression.

Figure 7

(A–C) WT mice were fed control or alcohol diet. At day 14 (A and B) or day 28 (C), mice were started on daily injections of IL-1Ra (anakinra; 25 mg/kg) or saline i.p. and sacrificed 2 weeks later. Liver histologies from days 14 and 28 were stained with H&E and Oil-red-O (A), and ALT was measured in the serum (B and C). (A and B) n = 5 (pair-fed saline and pair-fed IL-1Ra); 17 (EtOH-fed saline and EtOH-fed IL-1Ra). (C) n = 5 (pair-fed saline and pair-fed IL-1Ra); 9 (EtOH-fed saline and EtOH-fed IL-1Ra). *P < 0.05 vs. pair-fed. (D and E) WT mice were fed control or alcohol diet. After day 14, mice were started on daily injections of IL-1Ra or saline i.p. and sacrificed 5 weeks later. The progression of liver injury was evaluated by measuring serum ALT (D). Liver histologies from days 14 (week 2) and 49 (week 7) were stained with H&E and Oil-red-O (E). n = 5 (pair-fed saline and pair-fed IL-1Ra); 40 (EtOH-fed saline); 29 (EtOH-fed IL-1Ra). At the end of experiment (week 7), survival was 23% in the EtOH-fed saline group and 48% in the EtOH-fed IL-1Ra group (P = 0.036). *P < 0.05 vs. EtOH-fed IL-1Ra; #P<0.05 vs. week 2.
