Multiple sclerosis (MS) is a common chronic inflammatory demyelinating disease of the central nervous system (CNS) causing progressive disability. Many observations implicate Epstein-Barr virus (EBV) in the pathogenesis of MS, namely universal EBV seropositivity, high anti-EBV antibody levels, alterations in EBV-specific CD8(+) T-cell immunity, increased spontaneous EBV-induced transformation o...
conclusions considering the results, accurate and on time diagnosis of ebv primary infection in both children and adolescents will help prevent unnecessary hospitalization, medication and incorrect medical decisions. in addition, this will decrease further treatment costs and related medical procedures. background many children become infected with epstein-barr virus (ebv) during their childhoo...
سابقه و هدف: مالتیپل اسکلروزیس (ms) یک بیماری التهابی پیچیده سیستم عصبی مرکزی است که خود ایمنی علیه میلین در ایجاد این بیماری نقش دارد. میزان شیوع بیماری ms، از هر 100000 نفر نزدیک به 52 نفر گزارش شده است. وابستگی ms با عفونت اپشتین بار ویروس (ebv) به خوبی مستند شده است ولی در مطالعات انجام شده نتایج متفاوتی گزارش شده است. هدف از این مطالعه تعیین شیوع آنتی بادی igm و igg علیه آنتی ژن کپسید ebv ...
OBJECTIVE The detection rate of Epstein-Barr virus (EBV) is higher in people living with human immunodeficiency virus (HIV). In an attempt to contribute to our epidemiological understanding of this coinfection and to investigate the activity of EBV in normal oral mucosa, we performed a cross-sectional study with HIV-positive patients. METHODS Oral smears from 145 HIV-positive patients were co...
Currently, there is no characteristic microRNA (miRNA) expression pattern in Epstein-Barr virus+ diffuse large B-cell lymphoma of the elderly (EBV+DLBCLe). This study aims to characterize a signature profile and identify miRNAs that can be used as biomarkers and alternative therapeutic targets for EBV+DLBCLe. Seventy-one DLBCL patients aged 50 years and older were included and four EBV+ and fou...
We used a modified subtractive suppression hybridization to identify cellular genes that show altered expression in Burkitt lymphomas (BLs) in the presence of Epstein-Barr virus (EBV). Comparison of the gene expression patterns of an EBV-negative clone of the originally EBV-positive BL line Akata, with its Neo(R)-EBV derivative, revealed a significant difference in the expression of the T cell ...
Epstein-Barr virus (EBV) is associated with Burkitt's lymphoma (BL), and in regions of sub-Saharan Africa where endemic BL is common, both the EBV Type 1 (EBV-1) and EBV Type 2 strains (EBV-2) are found. Little is known about genetic variation of EBV strains in areas of sub-Saharan Africa. In the present study, spontaneous lymphoblastoid cell lines (LCLs) were generated from samples obtained fr...
PURPOSE Circulating EBV DNA analysis has been shown to be valuable in the detection, prognostication, and monitoring of nasopharyngeal carcinoma (NPC) patients. A previous study has shown that, after radiotherapy, plasma EBV DNA levels of NPC patients would decline exponentially with a median half-life of 3.8 days. We postulate that this decline in plasma EBV DNA reflects the decrease in cancer...
Epstein-Barr virus (EBV) is associated with various malignancies, including epithelial cancers. In this study, we analyzed the effect of EBV infection on epithelial cells by using EBV-converted epithelial cells. In EBV-positive cells, the extracellular signal-regulated kinase (ERK) pathway is constitutively activated. Inhibition of ERK activity leads to reduced anoikis resistance; therefore, EB...
Background and purpose: The association of nasopharyngeal carcinoma (NPC) and Epstein-Barr virus (EBV) was firmly established as early as 1973. A clear understanding of its etiology is still lacking, but nasopharyngeal carcinoma is widely suspected to be the result of both a genetic susceptibility and exposure to environmental factors or Epstein-Barr virus infection. NPC is more prevalent in yo...
