Epstein-Barr virus latent membrane protein 1 (LMP1) is expressed in multiple human malignancies, including nasopharyngeal carcinoma and Hodgkin and immunosuppression-associated lymphomas. LMP1 mimics CD40 signaling to activate multiple growth and survival pathways, in particular, NF-κB. LMP1 has critical roles in Epstein-Barr virus (EBV)-driven B-cell transformation, and its expression causes f...

Chronic active Epstein-Barr virus infection (CAEBV) has been considered to be a non-neoplastic T-cell lymphoproliferative disease associated with Epstein-Barr virus (EBV) infection. In EBV-associated diseases, the cell phenotype-dependent differences in EBV latent gene expression may reflect the strategy of the virus in relation to latent infection. We previously reported that EBV latent gene e...

BACKGROUND/AIMS Gastric cancer (GC) is the second leading cause of cancer-related deaths worldwide and is the most frequent cancer in Iran. Epstein-Barr virus (EBV) has been shown to be associated with gastric cancer. The present study was carried out to investigate the prevalence of Epstein-Barr virus (EBV) associated gastric cancer among Iranian patients. METHODS Ninety formalin fixed paraf...

A 38-year-old male was admitted with fever, progressive jaundice, cervical lymphadenopathy, hepatomegaly and acute oliguric renal failure. Epstein-Barr virus (EBV) infection was diagnosed by detection of EBV-DNA in plasma and confirmed by EBV seroconversion. Kidney biopsy revealed acute tubular necrosis and abundant casts, consisting of bilirubin pigment. With conservative treatment, the patien...

Epstein-Barr virus (EBV) is involved in numerous lymphoproliferative diseases. In addition to classical lesions such as endemic Burkitt's lymphoma and infectious mononucleosis, there are other disorders of the lymphoid system that are discussed in relation to EBV: B-cell lymphomas in immunosuppressed individuals. Hodgkin's disease and, to some extent, primary extranodal lymphomas. Studies of th...

We have studied by the in situ hybridization method the presence of Epstein-Barr virus (EBV) DNA genome in lymph node tissues from 11 patients with persistent generalized lymphadenopathy. Using a biotinylated EBV DNA probe, we demonstrated EBV nucleic acid in scattered germinal centre cells in eight of the 11 cases. Our results suggest that EBV is not a determinant factor in the pathogenesis of...

The molecular diversity of Epstein–Barr virus (EBV) is exceptionally complex and based on the characterization sequences coding for several viral genes. aim this study was to analyze distribution EBV types 1 2 characterize LMP1 variants in a cohort 73 patients with infectious mononucleosis (IM), as well investigate possible association between relevant clinical parameters. Population-based sequ...

An immunoglobulin M (IgM) enzyme-linked immunosorbent assay (ELISA) was developed by using a 24-amino-acid peptide of the 18-kDa Epstein-Barr virus (EBV) viral capsid antigen (VCAp18). IgM detection was increased by 23% by using this antigen. Detection of IgM antibodies to the EBV proteins in the new ELISA was 100% specific and 95% sensitive.

We report a case of primary cutaneous CD30+ post-transplant lymphoproliferative disorder with an uncommon finding of signet ring cell features in a heart transplant patient. The neoplastic cells were CD4 and CD30 positive, and negative for S-100, pancytokeratin, myeloperoxidase, and CD56. In situ hybridization for Epstein Barr Virus (EBV) was negative, even though the patient did have EBV viremia.

A patient presented with fever, night sweats, generalized lymphadenopathy, cold agglutinin hemolytic anemia, and thrombocytopenia. Lymph node biopsy revealed a lymphoplasmacytic infiltrate sparing the cortical sinuses but associated with arborizing blood vessels. Epstein-Barr virus (EBV) DNA was demonstrated in tissue from an involved lymph node. These data suggest an association of EBV with a ...
