INTRODUCTION We present a case of an unusual clinical manifestation of Guillain-Barre syndrome following a pre-existing herpes virus infection. Although there have been several reports describing the co-existence of herpes virus infection and Guillain-Barre syndrome, we undertook a more in-depth study of the cross-reactivity between herpes viruses and recommend a follow-up study based on serolo...

INTRODUCTION Systemic Epstein-Barr-virus-positive T cell lymphoproliferative disease of childhood is an extremely rare disorder, characterized by clonal proliferation of Epstein-Barr-virus-infected T cells with an activated cytotoxic phenotype. The disease is more frequent in Asia and South America, with only few cases reported in Western countries. A prompt diagnosis, though often difficult, i...

Epstein-Barr virus is an unusual pathogen in the aetiology of alveolitis. We describe a case of Epstein-Barr virus induced pneumonitis and its successful treatment with Aciclovir.

We report a patient with X-linked lymphoproliferative disease (XLP) who developed multiple central nervous system (CNS) manifestations of Epstein-Barr virus infection. XLP, or Duncan syndrome, is a rare inherited disorder characterized by the inability to clear Epstein-Barr virus infection. In addition to Epstein-Barr virus encephalitis, CNS lymphoproliferative disease, and lymphoma, this patie...

    Abstract   Background: Multiple sclerosis (MS) is the most common autoimmune disease of central nervous system with destruction of myelin sheath mediated by auto reactive CD4+ T Lymphocytes. Because of the possible role of Epstein-Barr virus in etiology of MS and T cells immune response, the aim of this study was to evaluate anti-Epstein Barr virus antibodies as a marker of reactivity and p...

Fulminant hepatitis by Epstein-Barr virus is a rare event which is predominantly due to primary infection. We report a rare case of fatal hepatic failure due to Epstein-Barr virus reactivation in a 19-year-old boy who was taking oral steroids. Transaminase peak and the fulminant course of the disease began soon after steroid interruption. Epstein-Barr virus reactivation was diagnosed on the bas...

USP7 (also called HAUSP) is a de-ubiquitinating enzyme recently identified as a key regulator of the p53-mdm2 pathway, which stabilizes both p53 and mdm2. We have discovered that the Epstein-Barr nuclear antigen 1 protein of Epstein-Barr virus binds with high affinity to USP7 and disrupts the USP7-p53 interaction. The results have important implications for the role of Epstein-Barr nuclear anti...

Attempts were made to superinfect epithelial explant cell cultures prepared from nasopharyngeal carcinomas with Epstein-Barr virus. Virus-specific markers were observed in such cultures 3 days after superinfection. In addition, expression of Epstein-Barr virus early antigens was observed in epithelial cell explant cultures treated with iododeoxyuridine. The results suggest that epithelial cells...

Lymphocytes were infected with the QIMR-WIL strain of Epstein-Barr virus, and the induction of Epstein-Barr virus-associated nuclear antigens was determined by using the protein immunoblot. There was a temporal increase in six antigens, with Epstein-Barr nuclear antigen 2 being detected 1 day after infection. The appearance of these antigens was shown to be independent of cellular DNA synthesis.

Immunoglobulin M (IgM) antibodies to Epstein-Barr virus were detected by using microtiter plates coated with anti-mu-chain antiserum and enzyme-labeled Epstein-Barr virus antigen. Optimum conditions for labeling were determined. The addition of unlabeled control antigen to the enzyme-labeled antigen was effective in reducing background reactions. Rheumatoid factor no longer interfered. Blocking...
