Poly I:C/D-GalN induced liver injury correlates to the increased CRACC mRNA expression of liver.

<p><b>A</b>, Mice were treated with Poly I:C (1.5 µg per mouse, i.v.) together with D-GalN (10 mg per mouse, i.p.); and then euthanized at 2h, 4h, 6h, 8h, 12h, 18h, 24h, 48h time points post Poly I:C/D-GalN treatment. The expression of CRACC mRNA was assayed by quantitative PCR (upper panel); and the serum ALT was tested (lower panel). <b>B</b>, Mice were treated with saline alone, Poly I:C alone, D-GalN alone or Poly I:C together with D-GalN for 12h; and then the CRACC expression on Kupffer cells and hepatic NK cells was analyzed by flow cytometry. Kupffer cells were identified as F4/80⁺ cells and NK cells were identified as NK1.1 ⁺ CD3^- cells. Data are from 6-9 mice per group.
