ارتباط بین سرطان نازوفارنکس(npc) با ویروس اپشتین-بار(ebv) اولین بار در سال 1973 مشخص شد. با این وجود، نقش ویروس در آسیب ¬شناسی npc هنوز مورد بحث است. تصویر روشنی از علت این سرطان وجود ندارد، با این حال سرطان نازوفارنکس را به احتمال زیاد نتیج‍ة استعداد ژنتیکی و در معرض عوامل محیطی یا عفونت ebv می¬دانند. به خاطر شیوع بالای npc در سنین جوانی از یک طرف و جوان بودن جمعیت کشورمان از سوی دیگر، این مطا...

  Background and Objectives: Epstein Barr Virus (EBV) is one of the members of herpesviridae family and a sub-category of Gamma herpes virinae. EBV, which normally has CR2 or CD21 receptors on B-lymphocytes, has mutagenic features for them. The virus plays an important role in causing some malignant cancers. About 30% of the cases with non-Hodgkin’s lymphoma are diffuse large B-cell l...

Background and Aims: Epstein-Barr virus (EBV) infection is very common in the population. Virus belongs to the family Herpesviridae, whose representatives are characterized by the ability to cause the human body latent persistent infections. The goal of this study was to assess EBV infection frequency using PCR method in samples from inflammatory eye disease, in comparison with EBV presence in ...

Simultaneous infection with Epstein-Barr virus (EBV) and Helicobacter pylori (H. pylori) can occur. Several researchers suggested that H. would accelerate to the occurrence development of EBV-positive gastric cancer (EBV-GC). However, possible interaction in carcinogenesis is still debatable. From January 2020 December 2021, a retrospective cohort study was performed 27 patients EBV-GCs. During...

Background: environmental factors may play a role in colon cancer. In this view, several studies investigated tumor samples for the presence of various viral DNA with conflictiong results.  The purpose of this study is to investigate the prevalence of Human papillomaviruses (HPVs) and Epstein–Barr virus (EBV) in patients with colorectal carcinomas. Materials and methods: In this  study, we co...

Background and Objective: The association of EBV with Hodgkin Lymphoma (HL) has been intensely investigated over the last few years. EBV is also associated with several other malignancies. On the other hand, Ki67 molecule serves as a widely accepted proliferation marker. Several studies were previously p...

Introduction: Burkitt lymphoma (BL) is an aggressive mature B-cell lymphoma, which traditionally has been separated into three epidemiologic variants: endemic (eBL), sporadic (sBL) and immunodeficiency-associated BL (iBL). This subgrouping strongly confounded by EBV-infection. Indeed, there evidence from molecular studies that subtyping of based on EBV status might better reflect the pathogenet...
