The Role of Extracellular Vesicles in Liver Pathogenesis.

Am J Pathol 2022 Jun 22. Epub 2022 Jun 22.

Department of Pathology and Laboratory Medicine, Tulane University School of Medicine, New Orleans, LA, 70112. Electronic address:

Extracellular vesicles are generated by cells in the form of exosomes, microvesicles and apoptotic bodies. They can be taken by neighboring cells and their contents can have functional impact on cells that engulf them. As the mediators of intercellular communication, extracellular vesicles can play important roles in both physiological and pathological contexts. Read More

Primary non-Hodgkin lymphoma of the extra-hepatic bile duct: A case report.

Mol Clin Oncol 2022 Jul 25;17(1):115. Epub 2022 May 25.

Third Department of Surgery, National and Kapodistrian University of Athens, Attikon University Hospital, 12462 Athens, Greece.

Lymphoma is known to be a systemic lymphoproliferative malignancy, which is divided into two subtypes: Hodgkin lymphoma and non-Hodgkin lymphoma. Non-Hodgkin lymphoma originates from nodal and extranodal sites. In the staging of non-Hodgkin lymphoma, the liver is implicated in 40% of cases; however, primary liver non-Hodgkin lymphoma represents <1% of all non-Hodgkin lymphoma cases. Read More

Genetic Analysis of Mutations and Variants Related to the Pathogenesis and Pathophysiology of Low Phospholipid-Associated Cholelithiasis.

Genes (Basel) 2022 Jun 11;13(6). Epub 2022 Jun 11.

Department of Medicine and Genetics, Division of Gastroenterology and Liver Diseases, Marion Bessin Liver Research Center, Einstein-Mount Sinai Diabetes Research Center, Albert Einstein College of Medicine, Bronx, NY 10461, USA.

Clinical studies have revealed that the gene encodes the phospholipid transporter on the canalicular membrane of hepatocytes, and its mutations and variants are the genetic basis of low phospholipid-associated cholelithiasis (LPAC), a rare type of gallstone disease caused by a single-gene mutation or variation. The main features of LPAC include a reduction or deficiency of phospholipids in bile, symptomatic cholelithiasis at <40 years of age, intrahepatic sludge and microlithiasis, mild chronic cholestasis, a high cholesterol/phospholipid ratio in bile, and recurrence of biliary symptoms after cholecystectomy. Needle-like cholesterol crystals, putatively "anhydrous" cholesterol crystallization at low phospholipid concentrations in model and native bile, are characterized in ABCB4 knockout mice, a unique animal model for LPAC.

Mucosal-Associated Invariant T Cells in T-Cell Non-Hodgkin Lymphomas: A Case Series.

Cancers (Basel) 2022 Jun 14;14(12). Epub 2022 Jun 14.

Internal Medicine and Hepatology Unit, University Hospital "San Giovanni di Dio e Ruggi d'Aragona", University of Salerno, 84131 Salerno, Italy.

Background: Mucosal-associated invariant T (MAIT) cells are a subset of unconventional T lymphocytes expressing a semi-invariant α/β T-cell receptor (TCR). The physiological functions of these cells, which are particularly abundant in normal liver and mucosal sites, have become clear only in recent years, but their role in most human diseases is still unknown. Since the cellular origin and etiopathogenesis of most T-lymphomas are still elusive, we decided to explore the presence of MAIT cells in biopsies from these neoplasms. Read More

A Laboratory-Friendly CTC Identification: Comparable Double-Immunocytochemistry with Triple-Immunofluorescence.

Cancers (Basel) 2022 Jun 10;14(12). Epub 2022 Jun 10.

Translational Oncology Laboratory, Avera Research Institute, Sioux Falls, SD 57105, USA.

The source of circulating tumor cells (CTC) in the peripheral blood of patients with solid tumors are from primary cancer, metastatic sites, and a disseminated tumor cell pool. As 90% of cancer-related deaths are caused by metastatic progression and/or resistance-associated treatment failure, the above fact justifies the undeniable predictive and prognostic value of identifying CTC in the bloodstream at stages of the disease progression and resistance to treatment. Yet enumeration of CTC remains far from a standard routine procedure either for post-surgery follow-ups or ongoing adjuvant therapy. Read More

Identification of the Potential Molecular Mechanisms Linking RUNX1 Activity with Nonalcoholic Fatty Liver Disease, by Means of Systems Biology.

Biomedicines 2022 Jun 3;10(6). Epub 2022 Jun 3.

Grup de Recerca GEMMAIR (AGAUR)-Medicina Aplicada (URV), Departament de Medicina i Cirurgia, Institut d'Investigació Sanitària Pere Virgili (IISPV), Universitat Rovira i Virgili (URV), 43007 Tarragona, Spain.

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic hepatic disease; nevertheless, no definitive diagnostic method exists yet, apart from invasive liver biopsy, and nor is there a specific approved treatment. Runt-related transcription factor 1 (RUNX1) plays a major role in angiogenesis and inflammation; however, its link with NAFLD is unclear as controversial results have been reported. Thus, the objective of this work was to determine the proteins involved in the molecular mechanisms between RUNX1 and NAFLD, by means of systems biology. Read More

Combinational elastography for assessment of liver fibrosis in patients with liver injury.

J Int Med Res 2022 Jun;50(6):3000605221100126

Department of Internal Medicine II, Shimane University School of Medicine, Izumo, Japan.

Objective: We investigated the utility of combinational elastography with point shear wave elastography (pSWE) and real-time tissue elastography (RTE) for evaluating liver fibrosis in patients with liver injury.
