Patient-Derived Avatar Mouse Model to Predict the Liver Immune Homeostasis of Long-Term Stable Liver Transplant Patients. Front Immunol 2022; 13:817006.

Abstract
Although rejection or tolerance can occur in liver transplantation (LT) patients, there are no reliable non-invasive methods for predicting immune homeostasis. In this study, we developed a humanized mouse model to predict liver immune homeostasis in patients who underwent LT. The patient-derived avatar model was developed by injecting peripheral blood mononuclear cells from healthy controls (HCs) or LT patients with stable, rejection, or tolerance into NOD.Cg-PrkdcscidIL2rgtm1Wjl/SzJ (NSG) mice, followed by injection of human hepatic stellate cells and Carbone tetrachloride (CCl4). After 7 weeks, the patient’s T-cell engraftment and liver inflammation in the avatar model were evaluated and compared with the liver histology of LT patients. Changes in liver inflammation following treatment with tacrolimus and/or biguanide derivatives were also examined. The C-X-C Motif Chemokine Receptor 3 (CXCR3)-dependently engrafted patient T cells led to differences in liver inflammation in our model according to the status of LT patients. The livers of avatar models from rejection patients had severe inflammation with more T helper 17 cells and fewer regulatory T cells compared to those of models from tolerance and HCs showing only mild inflammation. Moreover, our model classified stable post-LT patients into severe and mild inflammation groups, which correlated well with liver immunity in these patients. Our models revealed alleviation of inflammation after combination treatment with tacrolimus and biguanide derivatives or monotherapy. Consequently, using our new patient-derived avatar model, we predicted liver immune homeostasis in patients with stable LT without biopsy. Moreover, our avatar model may be useful for preclinical analysis to evaluate treatment responses while reducing risks to patients.

Abstract
Glutathione S-transferase placental form-positive (GST-P+) foci are markers of preneoplastic lesions in rat hepatocarcinogenesis. Our previous studies using reporter gene transgenic rats showed that furan, a hepatocarcinogen in rodents, rapidly induces the formation of GST-P+ foci after short exposure without reporter gene mutation. We hypothesized that GST-P+ foci induced by furan may have biological characteristics different from those induced by diethylnitrosamine (DEN), a genotoxic hepatocarcinogen. Accordingly, we compared the cell kinetics of GST-P+ foci after cessation of DEN treatment and performed comprehensive gene expression in DEN- or furan-induced GST-P+ foci. The number and area of DEN-induced GST-P+ foci were increased after cessation of treatment, whereas furan decreased these parameters. Size distribution analysis showed that large furan-induced GST-P+ foci disappeared after cessation of treatment. Hierarchical cluster analysis showed that all samples from GST-P+ foci induced by furan were separated from those induced by DEN. SOX9 expression was upregulated in furan-induced GST-P+ foci and was detected by immunohistochemistry in large furan-induced GST-P+ foci. Our results indicated that large furan-induced GST-P+ foci were quite different from DEN-induced GST-P+ foci at the molecular and cellular levels. And one of the properties of disappearing large GST-P+ foci were characterized by inclusion of hepatocytes expressing SOX9.

Abstract
The Nrf2 pathway protects against oxidative stress and induces regeneration of various tissues. Here, we investigated whether Nrf2 protects from sclerosing cholangitis and biliary fibrosis and simultaneously induces liver regeneration. Diet containing 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) was fed to Nrf2-KO mice (Nrf2-/-), mice with liver-specific hyperactivated Nrf2 (HKeap1-/-) and wild-type (WT) littermates to induce cholangitis, liver fibrosis, and oval cell expansion. HKeap1-/--mice were protected from almost all DDC-induced injury compared with WT and Nrf2-/-. Liver injury in Nrf2-/- and WT mice was mostly similar, albeit Nrf2-/- suffered more from DDC diet as seen for several parameters. Nrf2 activity was especially important for the expression of the hepatic efflux transporters Abcg2 and Abcc2-4, which are involved in hepatic toxin elimination. Surprisingly, cell proliferation was more enhanced in Nrf2-/-- and HKeap1-/--mice compared with WT. Interestingly, Nrf2-/--mice failed to sufficiently activate oval cell expansion after DDC treatment and showed almost no resident oval cell population under control conditions. The resident oval cell population of untreated HKeap1-/--mice was increased and DDC treatment resulted in a stronger oval cell expansion compared with WT. We provide evidence that Nrf2 activation protects from DDC-induced sclerosing cholangitis and biliary fibrosis. Moreover, our data establish a possible role of Nrf2 in oval cell expansion.

Abstract
Hepatic oval cells (HOCs) are recognized as facultative liver progenitor cells that
play a role in liver regeneration after acute liver injury. Here, we investigated the
in vitro proliferation and differentiation characteristics of
HOCs in order to explore their potential capacity for intrahepatic transplantation.
Clusters or scattered HOCs were detected in the portal area and interlobular bile
duct in the liver of rats subjected to the modified 2-acetylaminofluorene and partial
hepatectomy method. Isolated HOCs were positive for c-kit and CD90 staining (99.8%
and 88.8%, respectively), and negative for CD34 staining (3.6%) as shown by
immunostaining and flow cytometric analysis. In addition, HOCs could be
differentiated into hepatocytes and bile duct epithelial cells after leukemia
inhibitory factor deprivation. A two-cuff technique was used for orthotopic liver
transplantation, and HOCs were subsequently transplanted into recipients. Biochemical
indicators of liver function were assessed 4 weeks after transplantation. HOC
transplantation significantly prolonged the median survival time and improved the
liver function of rats receiving HOCs compared to controls (P=0.003, Student
t-test). Administration of HOCs to rats also receiving liver
transplantation significantly reduced acute allograft rejection compared to control
liver transplant rats 3 weeks following transplantation (rejection activity index
score: control=6.3±0.9; HOC=3.5±1.5; P=0.005). These results indicate that HOCs may
be useful in therapeutic liver regeneration after orthotopic liver
transplantation.

Abstract
Cholangiocarcinoma is an adenocarcinoma of the liver which has increased in incidence over the last thirty years to reach similar levels to other liver cancers. Diagnosis of this disease is usually late and prognosis is poor, therefore it is of great importance to identify novel candidate markers and potential early indicators of this disease as well as molecules that may be potential therapeutic targets. We have used a proteomic approach to identify differentially expressed proteins in peripheral cholangiocarcinoma cases and compared expression with paired non-tumoral liver tissue from the same patients. Two-dimensional fluorescence difference gel electrophoresis after labeling of the proteins with cyanines 3 and 5 was used to identify differentially expressed proteins. Overall, of the approximately 2,400 protein spots visualised in each gel, 172 protein spots showed significant differences in expression level between tumoral and non-tumoral tissue with p < 0.01. Of these, 100 spots corresponding to 138 different proteins were identified by mass spectrometry: 70 proteins were over-expressed whereas 68 proteins were under-expressed in tumoral samples compared to non-tumoral samples. Among the over-expressed proteins, immunohistochemistry studies confirmed an increased expression of 14-3-3 protein in tumoral cells while α-smooth muscle actin and periostin were shown to be overexpressed in the stromal myofibroblasts surrounding tumoral cells. α-Smooth muscle actin is a marker of myofibroblast differentiation and has been found to be a prognostic indicator in colon cancer while periostin may also have a role in cell adhesion, proliferation and migration and has been identified in other cancers. This underlines the role of stromal components in cancer progression and their interest for developing new diagnostic or therapeutic tools.

Abstract
Liver progenitors, so-called oval cells, proliferate remarkably from periportal areas after severe liver injury when hepatocyte regeneration is compromised. These cells invade far into the liver parenchyma. Molecular mechanisms underlying these behaviors of oval cells remain poorly understood. In this study, we treated rats with 2-acetylaminofluorene/carbon tetrachloride to induce hepatic oval cells. By expression microarray analysis, we investigated global gene expression profiles in liver tissue, with an emphasis on adhesion molecules, extracellular matrix proteins, matrix metalloproteinases (MMPs), growth factors/cytokines, and receptors that might contribute to the distinct behaviors of oval cells. Genes upregulated at least twofold were selected. We then performed immunostaining to verify the microarray results and identified expression of MMP-7 and CD44 in oval cells. Staining of cytokeratin (CK)-19, an oval-cell marker, was similar between oval cells located next to periportal areas and those located far within the parenchyma. In contrast, CD44 staining was more intense in the parenchyma than in periportal areas, suggesting a role of CD44 in oval-cell invasion. Moreover, newly differentiated CK-19+ hepatocytes within foci did not show CD44 staining, suggesting that CD44 is related to the undifferentiated oval-cell phenotype. We then investigated oval-cell reactivity in CD44-deficient mice fed an oval cell-inducing diet of 3,5-diethoxycarbonyl-1,4-dihydrocollidine. Results showed significantly reduced oval-cell reactivity in CD44-deficient mice. Thus, oval cells express MMP-7 and CD44, and CD44 appears to play critical roles in the proliferation, invasion, and differentiation of hepatic oval cells in rodents.

Abstract
Many chronic liver diseases can lead to hepatic dysfunction with organ failure. At present, orthotopic liver transplantation represents the benchmark therapy of terminal liver disease. However this practice is limited by shortage of donor grafts, the need for lifelong immunosuppression and very demanding state-of-the-art surgery. For this reason, new therapies have been developed to restore liver function, primarily in the form of hepatocyte transplantation and artificial liver support devices. While already offered in very specialized centers, both of these modalities still remain experimental. Recently, liver progenitor cells have shown great promise for cell therapy, and consequently they have attracted a lot of attention as an alternative or supportive tool for liver transplantation. These liver progenitor cells are quiescent in the healthy liver and become activated in certain liver diseases in which the regenerative capacity of mature hepatocytes and/or cholangiocytes is impaired. Although reports describing liver progenitor cells are numerous, they have not led to a consensus on the identity of the liver progenitor cell. In this review, we will discuss some of the characteristics of these cells and the different ways that have been used to obtain these from rodents. We will also highlight the challenges that researchers are facing in their quest to identify and use liver progenitor cells.

Abstract
HFAK-RC caused pronounced leukopenia, increase in TXB2 levels in plasma and hemodynamic pressure changes as a reflection of complement activation during EC in sheep. In contrast no increase in TXB2 levels and no changes in hemodynamics are observed with HFAK-MC. The leukopenia and granulocytopenia in the latter is much less pronounced and probably reflects the phenomenon "frustrated phagocytosis".
