METHODS: We generated transgenic (TG) mice with hepatocyte expression of rat IL-10 (rIL-10) to assess its impact on lymphocyte subsets and activation of hepatic stellate cells following liver injury from carbon tetrachloride (CCl 4 ) or thioacetamide (TAA).

METHODS: Hepatic fibrosis was induced by biweekly intra-peritoneal (IP) carbon tetrachloride (CCl (4)) administrations for 7 weeks in 5 groups (A-E) of male C57Bl/6 mice.

METHODS: Forty Wistar rats were randomly divided into 2 groups: cirrhosis group (n = 25) undergoing subcutaneous injection of 40% carbon tetrachloride twice a week for 10-12 weeks to establish cirrhosis models, and control group (n = 15).
The T lymphocytes in the intestinal epithelium were isolated and labeled with mouse anti-rat CD3, CD4 and CD8 monoclonal antibody, Flow cytometry was performed.

Recent functional research studies suggest an anti-fibrotic role for natural killer (NK) cells coupled with a profibrotic role for CD8 cells.
To investigate lymphocyte/hepatic stellate cell (HSC) interactions, hepatic fibrosis was induced by administering carbon tetrachloride (CCl4) intraperitoneally (i.p.) for 4 weeks in C57Bl/6 mice.

Am J Physiol Gastrointest Liver Physiol. 2007 Feb;292(2):G628-38. Epub 2006 Oct 12.

While CD8 subsets activate hepatic fibrosis, natural killer (NK) cells exhibit antifibrotic activity.
Hepatic fibrosis was induced in C57BL/6 mice by intraperitoneal administration of carbon tetrachloride (CCl (4)) for 6 wk.

We examined the potential immunomodulatory actions of uPA, tPA and uPA-receptor (uPAR) in carbon-tetrachloride-induced hepatic fibrosis in wild-type (WT), tPA-/-, uPA-/- and uPAR-/- mice.
Following uPA exposure in vivo, there was CD8 predominance.

Unlike the anti-fibrotic effect of natural killer (NK) cells, CD8 and NK T subsets are considered as profibrogenic subsets.
Hepatic fibrosis was induced by 6 weeks of biweekly i.p. carbon tetrachloride (CCl4) injections in male C57Bl6 mice.

Although a variety of cell populations infiltrate the liver during inflammation, it is generically clear that CD8 T lymphocytes promote while natural killer (NK) cells inhibit liver fibrosis.
