While the impact of the dengue viruses on liver function is prominent as shown by hepatomegaly, liver enzyme abnormality, occasional fulminant hepatic failure and histological changes including hepatocellular necrosis, significant debate exists as to the possible involvement of the predominant cell type in the liver, hepatocytes, in the disease process. To address this issue purified human primary hepatocytes were exposed to dengue virus serotype 2 and the production of de novo viral progeny was established by standard plaque assay, RT-PCR and immunocytochemistry. To investigate the response of the primary hepatocytes to infection, the expression of a panel of 9 cytokine genes (IFN-beta, TRAIL, MCP-1, IL-6, IL-1beta, IL-8, MIP-1alpha, MIP-1beta, and RANTES) was semi-quantitatively investigated by RT-PCR and up-regulation of TRAIL, MIP-1alpha, IFN-beta, MIP-1beta, IL-8, and RANTES was observed in response to infection. The induction of IL-8 in response to infection was accompanied by the secretion of IL-8 as verified by ELISA assay. The ability of hepatocytes to be infected with dengue virus serotype 2 in vitro support evidence implicating human hepatocytes as a target cell in cases of dengue virus infection, and provide the first experimental evidence to support the large number of clinical studies that implicate the liver as a critical target organ in severe cases of dengue infection.

It has been demonstrated that an immune-modulating enteral formula enriched with whey peptides and fermented milk (IMF) had anti-inflammatory effects in some experimental models when it was administered before the induction of inflammation. Here, we investigated the anti-inflammatory effects of the IMF administration after the onset of systemic inflammation and investigated whether the IMF could improve the remote organ injuries in an acute pancreatitis (AP) model. Mice were fasted for 12 hours and then fed a choline-deficient and ethionine-supplemented diet (CDE diet) for 24 hours to induce pancreatitis. In experiment 1, the diet was replaced with a control enteral formula, and mice were sacrificed at 24-hour intervals for 96 hours. In experiment 2, mice were randomized into control and IMF groups and received the control formula or the IMF respectively for 72 hr or 96 hr. In experiment 1, pancreatitis was induced by the CDE diet, and inflammatory mediators were elevated for several days. Remote organ injuries such as splenomegaly, hepatomegaly, and elevation of the hepatic enzymes developed. A significant strong positive correlation was observed between plasma MCP-1 and hepatic enzymes. In experiment 2, the IMF significantly improved splenomegaly, hepatomegaly, and the elevation of hepatic enzymes. Plasma MCP-1 levels were significantly lower in the IMF group than in the control group. Nutrition management with the IMF may be useful for alleviating remote organ injuries after AP.
