We report on the characteristics of 21 patients with hepatosplenic ␥␦ T-cell lymphoma (HS␥␦TCL), an entity recognized since 1994 in the Revised Euro-pean American Lymphoma (REAL) classification. Median age was 34 years. Patients had splenomegaly (n ‫؍‬ 21), hepatomegaly (n ‫؍‬ 15), and thrombocy-topenia (n ‫؍‬ 20). Histopathologic findings were homogeneous(More)
Hepatic fibrosis, the major complication of virtually all types of chronic liver damage, usually begins in portal areas, and its severity has been correlated to liver progenitor cells (LPC) expansion from periportal areas, even if the primary targets of injury are intralobular hepatocytes. The aim of this study was to determine the potential fibrogenic role(More)
The Gas6/Axl pathway has been increasingly implicated in regeneration and tissue repair and, recently, in the control of innate immunity. In liver, we have demonstrated that Gas6 and its receptor Axl are expressed in macrophages, progenitor cells, and myofibroblasts and that Gas6 deficiency reduced inflammation and myofibroblast activation, causing delayed(More)
BACKGROUND/AIMS Resident macrophages and myofibroblasts derived from hepatic stellate cells play a key role in liver wound healing. We previously reported that these sinusoidal cells secrete the growth arrest-specific protein 6 (Gas6) and express Axl, one of its receptors. Here we address the role of Gas6 in the healing process during acute liver injury. (More)
BACKGROUND AND AIMS We aimed to determine the best algorithms for the diagnosis of significant fibrosis in chronic hepatitis C (CHC) patients using all available parameters and tests. PATIENTS AND METHODS We used the database from our study of 507 patients with histologically proven CHC in which fibrosis was evaluated by liver biopsy (Metavir) and tests:(More)
