Gamma-herpesviruses infect lymphocytes and cause lymphocytic cancers. Murid Herpesvirus-4 (MuHV-4), Epstein-Barr virus and the Kaposi's Sarcoma-associated Herpesvirus all infect B cells. Latent infection can spread by B cell recirculation and proliferation, but whether this alone achieves systemic infection is unclear. To test the need of MuHV-4 for lytic infection in B cells we flanked its essential ORF50 lytic transactivator with loxP sites, then infected mice with B cell-specific cre expression (CD19-cre)...

Despite overwhelming experimental work, there are no licensed vaccines against the most frequent Alphaherpesviruses, namely herpes simplex virus 1 and 2 (HSV1 and 2) nor against the Epstein-Barr virus (EBV), a member of the subfamily Gammaherpesvirus. Areas covered: Since the DNAs of both HSVs reside in the regional sensory ganglia in a latent state (i.e. as circularized episomal molecules), a corresponding vaccine might be useful for immunotherapy rather than prevention of primary infection. Here we describe the design of a purified subunit vaccine (a mix of at least 3 glycoproteins) as well as the preparation and efficacy of a recombinant fusion protein consisting of the gD ectodomain from our domestic attenuated HSV1 strain HSZP...

Infectious mononucleosis (IM) due to Epstein-Barr virus infection is common. Uric acid (UA) is an important endogenous antioxidant. To the best of our knowledge, the association between UA and IM has not been comprehensively investigated to date. The aim of the present study was to investigate this association in Chinese patients. A total of 95 patients (47 men and 48 women) with IM were recruited, along with 95 healthy controls. Clinical data were classified by patient sex. Receiver operating characteristic (ROC) curve analysis was adopted to determine the cut-off values of UA for IM diagnosis and prediction...

BACKGROUND: "Alice in Wonderland" syndrome (AIWS) is a rare neurological abnormality characterized by distortions of visual perceptions, body schema and experience of time. AIWS has been reported in patients with various infections such as infectious mononucleosis, H1N1 influenza, Cytomegalovirus encephalitis, and typhoid encephalopathy. However, AIWS occurring in a patient with severe malaria is less familiar and could pose serious primary care challenges in a low-income context. CASE PRESENTATION: A 9-year-old male of black African ethnicity was brought by his parents to our primary care hospital because for 2 days he had been experiencing intermittent sudden perceptions of his parents' heads and objects around him either "shrinking" or "expanding"...

In the present study, 21 cases of adult/late-onset EBV-associated lymphoproliferative disease (AELPD) with an uncertain malignant potential were investigated with regard to their histomorphology, immunophenotype, clonal rearrangement of the heavy chain (IgH) and T-cell receptor (TCR) genes and clinical course. The cases were histomorphologically reevaluated and assigned to one of three morphological groups: mononucleosis-like, Hodgkin-like, or polymorphous. In addition, cases with or without detectable necrosis were investigated for differences in clinical outcome...

BACKGROUND: The Epstein-Barr virus (EBV) is the causative agent of infectious mononucleosis. EBV is highly prevalent lymphotropic herpesvirus and has been linked to several malignancies. Transmission is generally by oral secretions, but can be through blood transfusions and organ transplantations. This study aimed to determine the seroprevalence, viremia rates, and circulating genotypes of EBV in healthy blood donors in Qatar. METHODS: Blood samples from 673 blood donors of different nationalities residing in Qatar (mainly Qatar, Egypt, Syria, Jordan, Pakistan, and India) were collected and tested for anti-EBV capsid (VCA; IgG & IgM), nuclear (EBNA; IgG), and early (EA-D; IgG) antigens...

Fifty years after the discovery of Epstein-Barr virus (EBV), it remains unclear how primary infection with this virus leads to massive CD8 T-cell expansion and acute infectious mononucleosis (AIM) in young adults. AIM can vary greatly in severity, from a mild transient influenza-like illness to a prolonged severe syndrome. We questioned whether expansion of a unique HLA-A2.01-restricted, cross-reactive CD8 T-cell response between influenza virus A-M158 (IAV-M1) and EBV BMLF1280 (EBV-BM) could modulate the immune response to EBV and play a role in determining the severity of AIM in 32 college students...

BACKGROUND: Epstein-Barr virus (EBV) was the first human virus identified to express microRNA (miRNA). To date, 44 mature miRNAs are encoded for within the EBV genome. EBV miRNAs have not been profiled in paediatric renal transplant recipients. In this study, we investigated circulating EBV miRNA profiles as novel biomarkers in paediatric renal transplant patients. METHODS: Forty-two microRNAs encoded within 2 EBV open reading frames (BART and BHRF) were examined in renal transplant recipients who resolved EBV infection (REI) or maintained chronic high viral loads (CHL), and in non-transplant patients with acute infectious mononucleosis (IM)...

A severe course of infectious mononucleosis should always lead up to the suspicion of a primary immunodeficiency. We describe the case of a boy with severe mononucleosis accompanied by the development of hemophagocytic lymphohistiocytosis and lymphoma. By whole exome sequencing, we identified a mutation of uncertain significance in CTPS2, a gene closely related to CTPS1, which is involved in a primary immune deficiency with susceptibility to herpesviruses. We discuss the challenge of a correct interpretation of data from whole exome sequencing, questioning whether the CTPS2 variant found in our patient is just an incidental finding or a mutation with variable penetrance...

Epstein-Barr virus (EBV) is the causative agent of infectious mononucleosis. Burkitt's lymphoma, nasopharyngeal carcinoma and post-transplant lymphoproliferative diseases are also associated with EBV. Diagnosis is frequently based on detection of specific antibodies. Using three parameters (anti VCA-IgM, anti VCA-IgG and anti EBNA-1 IgG), it is possible to define infection status and diagnose acute or past infection. However, sometimes the detection of atypical serological profiles makes it difficult to interpret these results...

Despite extensive studies focusing on the changes in expression of microRNAs (miRNAs) in multiple sclerosis (MS) compared to healthy controls, few studies have evaluated the association of genetic variants of miRNAs with MS clinical course. We investigated whether a functional polymorphism in the MS associated miR-146a gene predicted clinical course (hazard of conversion to MS and of relapse, and annualized change in disability), using a longitudinal cohort study of persons with a first demyelinating event followed up to their 5-year review...

Background: Epstein-Barr virus (EBV) has been found to cause infectious mononucleosis multiple times, but has been associated rarely with EBV encephalitis. Also, whenever it is diagnosed, it is always treated symptomatically. Case report: A case of confirmed EBV encephalitis is presented, which was treated with antiviral therapy resulting in complete clearance of the virus in cerebrospinal fluid and minimal neurologic symptoms after hospital discharge. Conclusion: The Infectious Diseases Society of America guidelines state that intravenous acyclovir is not recommended for EBV-related encephalitis...

Epstein-Barr virus is a very common human virus that infects 90% of human adults. EBV replicates in epithelial and B cells and causes infectious mononucleosis. EBV infection is also linked to various cancers, including Burkitt's lymphoma and nasopharyngeal carcinomas, and autoimmune diseases such as multiple sclerosis. Currently, there are no effective drugs or vaccines to treat or prevent EBV infection. Herein, we applied a computer-aided strategy to design a prophylactic epitope vaccine ensemble from experimentally defined T and B cell epitopes...

BACKGROUND: Disseminated Lyme disease can be difficult to diagnose, as it begins with nonspecific signs and symptoms, which, if not treated correctly, can lead to atrioventricular conduction blocks and meningitis. In addition, the diagnosis can be further complicated by potentially false-positive test results. CASE REPORT: We report a case of early-disseminated Lyme disease presenting with Borrelia meningitis and concomitant Lyme carditis, which was misdiagnosed as mononucleosis...

Over 90% of the world's population is persistently infected with Epstein-Barr virus. While EBV does not cause disease in most individuals, it is the common cause of acute infectious mononucleosis (AIM), has been associated with several cancers and autoimmune diseases, highlighting a need for a preventive vaccine. At present, very few primary, circulating EBV genomes have been sequenced directly from infected individuals. While low levels of diversity and viral evolution rates have been predicted for dsDNA viruses, recent studies have demonstrated appreciable diversity in common dsDNA pathogens (e...
