Unusual Epstein-Barr virus (EBV) infection into T or natural killer cells plays a pivotal role in the pathogenesis of acute EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) and chronic active EBV infection (CAEBV). The precise frequency and localization of EBV genome in lymphocyte subpopulations especially within T-cell subpopulations are unclear in these EBV-related disorders. This ...
Background: Epstein–Barr virus (EBV) is a universal herpes virus which can cause a life-long and largely asymptomatic infection in the human population. However, the exact pathogenesis of the EBV infection is not well known.Objective: A comprehensive bioinformatics prediction was carried out for investigating the molecular properties of the BGLF2 and to a...
Background & Objective: Idiopathic pulmonary fibrosis (IPF) is a chronic and uniformly fatal interstitial lung disease with incompletely understood pathogenesis. Several studies have given the evidence for and against viral cofactors in the pathogenesis of Idiopathic pulmonary fibrosis. In this study Epstein-Bar Virus (EBV) and Human Herpesvirus 8 (HH...
سابقه و هدف: لوپوس اریتماتوز سیستمیک (SLE) یک بیماری خودایمنی است که ریسک فاکتورهای محیطی مانند اشعه فرابنفش، داروها و عفونت ها مثل ویروس اپشتاین- بار (EBV) در ایجاد آن نقش دارند. این مطالعه با هدف بررسی بار سرمی EBV در بیماری SLE صورت گرفته است. مواد و روش ها: مطالعه مقطعی حاضر بر روی 40 بیمار مبتلا به SLE با تشخیص بر اساس معیارهای انجمن روماتولوژیک آمریکا و مراجعه‌کننده به درمانگاه روماتولوژی...
Background: Scleroderma is a chronic systemic disorder that affects the connective tissues. It is characterized by several immune manifestations, inflammation, vascular damage, and fibrosis. Some of the viral infections with complex mechanisms are involved in the development and progression of many autoimmune diseases, such as scleroderma. The present study aimed to investigate the serological ...
Abstract The objective of this study was to detect the Epstein–Barr virus (EBV) coinfection in coronavirus disease 2019 (COVID-19). In retrospective single-center study, we included 67 COVID-19 patients with onset time within 2 weeks Renmin Hospital Wuhan University from January 9 February 29, 2020. Patients were divided into EBV/SARS-CoV-2 group and SARS-CoV-2 infection alone according serolog...
background and aims: infectious mononucleosis (im)is the clinical manifestation of primary infection with epstein-barr virus (ebv). humans are the only known reservoir of ebv. regarding the problems in diagnosis of the disease, the purpose of this study was to assess enzyme-linked immunosorbent assay (elisa) and nested polymerase chain reaction (pcr) as a diagnostic tool for this disease. mater...
Herpesviruses are main sculptors of natural killer (NK) cell repertoires. While the ?-herpesvirus human cytomegalovirus (CMV) drives accumulation adaptive NKG2C-positive NK cells, ?-herpesvirus Epstein–Barr virus (EBV) expands early differentiated NKG2A-positive cells. cells support immunity by antibody-dependent cellular cytotoxicity, seem to preferentially target lytic EBV replicating B The i...
Epstein-Bar virus (EBV), a human herpesvirus, establishes a life-long persistent infection in 90 approximately 95% of human adult population worldwide. EBV is the etiologic agent of infectious mononucleosis, and EBV is associated with a variety of human malignancy including lymphoma and gastric carcinoma. Recently, EBV has been classified as group 1 carcinogen by the WHO International Agency fo...
Introduction: Latent EBV infection of the cHL clone is more frequent in mixed-cellularity (MC) histological subtype, early childhood and older adulthood, developing countries. Based on these other epidemiologic features, EBV+ has been hypothesized to have distinct etiology pathogenesis compared EBV− cHL. However, landscape genetic lesions genome incompletely defined. Methods: We studied 57 case...
