The Epstein-Barr virus (EBV) is a ubiquitous pathogen that infects over 90 % of adults. EBV is the primary etiological agent of infectious mononucleosis and is closely associated with nasopharyngeal carcinoma, gastric carcinoma, Hodgkin lymphoma and Burkitt lymphoma. Clinical serological assays for EBV diagnosis only survey a small portion of the viral proteome, which does not represent the total antigenic breadth presented to the immune system during viral infection. In this study, we have generated an expression library containing the majority of EBV ORFs, and have systematically evaluated IgG responses to those EBV proteins in sera from EBV carriers...

Multiple Sclerosis (MS) is a chronic neurological disease with genetic and environmental risk factors. Epstein Barr-Virus (EBV) has been closely associated with MS but with a significant amount of conflicting evidence. Some of the evidence for EBV involvement in MS includes: almost 100% of MS patients showing past EBV infection, an association with Infectious Mononucleosis (acute EBV infection), higher titres of EBV antibodies associated with an increased risk of MS development, and an overall altered immune response to EBV found in peripheral blood and the CNS of MS patients...

Multiple Sclerosis (MS) is a chronic inflammatory and demyelinating disease of the central nervous system. MS likely results from a complex interplay between predisposing causal gene variants (the strongest influence coming from HLA class II locus) and environmental risk factors such as smoking, infectious mononucleosis and lack of sun exposure/vitamin D. However, little is known about the mechanisms underlying MS development and progression. Moreover, the clinical heterogeneity and variable response to treatment represent additional challenges to a comprehensive understanding and efficient treatment of disease...

Streptococcus pneumoniae is a main causative agent of serious invasive bacterial infections. However, concurrent infection with invasive pneumococcal disease (IPD) and viral infectious mononucleosis (IM) is rare. We report an infant with serotype 6C infection causing IPD occurring simultaneously with IM. A previously healthy 11-month-old girl referred to our hospital because of fever, leukopenia, and elevated C-reactive protein presented to us with disturbance of consciousness, tachycardia, tachypnea and agranulocytosis...

Epstein-Barr virus (EBV) is known to be associated with the development of malignant lymphoma and lymphoproliferative disorders (LPDs) in immunocompromised patients. EBV, a B-lymphotropic gamma-herpesvirus, causes infectious mononucleosis and oral hairy leukoplakia, as well as various pathological types of lymphoid malignancy. Furthermore, EBV is associated with epithelial malignancies such as nasopharyngeal carcinoma (NPC), salivary gland tumor, gastric carcinoma and breast carcinoma. In terms of oral disease, there have been several reports of EBV-related oral squamous cell carcinoma (OSCC) worldwide...

Epstein-Barr Virus (EBV) infection and lytic replication are known to induce a cellular DNA damage response. Previously we showed that the virally encoded BPLF1 protein interacts with and regulates several members of the translesion synthesis pathway (TLS), a DNA damage tolerance pathway, and that these cellular factors enhance viral infectivity. BPLF1 is a late lytic cycle gene, but the protein is also packaged in the viral tegument indicating that BPLF1 may function both early and late during infection. BPLF1 expresses deubiquitinating activity that is strictly conserved across the Herpesviridae; mutation of the active-site cysteine results in loss of enzymatic activity...

BACKGROUND: The present study aims to prospectively investigate possible biological and psychological factors present in college students who will go on to develop chronic fatigue syndrome (CFS) following Infectious Mononucleosis (IM). Identification of risk factors predisposing patients towards developing CFS may help to understand the underlying mechanisms and ultimately prevent its occurrence. Our study is enrolling healthy college students over the age of 18. Enrollment began in March of 2013 and is ongoing...

Burke A Cunha, Thulashie Sivarajah, Ismail Jimada
We present a case of an adult female with a past history of pulmonary sarcoidosis who presented with fever, night sweats, profound fatigue, and LUQ abdominal pain. Sarcoidosis is an afebrile disorder (excluding Lofgren's syndrome, Heerfordt's syndrome or neurosarcoidosis). Therefore, the presence of fever with sarcoidosis should suggest infection, usually viral, or lymphoma. Sarcoidosis-lymphoma syndrome describes the evolution of a lymphoma in long standing sarcoidosis. Fever aside, possible lymphoma is suggested by otherwise unexplained fever, pleural unilateral effusion, highly elevated ESR or ferritin levels...

BACKGROUND: To investigate mechanisms underlying our previous observation of a large rise in serum prostate-specific antigen, a marker of prostate pathology, during both sexually transmitted and systemic infections, we measured serum high-sensitivity C-reactive protein (hsCRP), a marker of systemic inflammation, in our previous case-control study of young, male US military members and compared our findings to those for PSA. METHODS: We measured hsCRP before and during infection for 299 chlamydia, 112 gonorrhea, and 59 non-chlamydial, non-gonococcal urethritis (NCNGU) cases; before and after infection for 55 infectious mononucleosis (IM) and 90 other systemic/non-genitourinary cases; and for 220-256 controls...

BACKGROUND: Recently, morbidities due to primary cytomegalovirus (CMV) infection have increased in young Japanese adults because of decreased anti-CMV antibodies in them. CMV infections are typically resolved naturally in immunocompetent individuals, and complications rarely occur. Here we present the case of an immunocompetent adult with CMV infection complicated by splenic infarctions and an esophageal ulcer. CASE REPORT: A 37-year-old male complaining of a prolonged fever and liver injury was admitted to hospital for a closed examination...

Epstein-Barr virus (EBV), human herpes virus 4, has been classically associated with infectious mononucleosis, multiple sclerosis and several types of cancers. Many of these diseases show marked geographical differences in prevalence, which points to underlying genetic and/or environmental factors. Those factors may include a different susceptibility to EBV infection and viral copy number among human populations. Since EBV is commonly used to transform B-cells into lymphoblastoid cell lines (LCLs) we hypothesize that differences in EBV copy number among individual LCLs may reflect differential susceptibility to EBV infection...

During recent years, various mumps outbreaks have occurred among populations vaccinated for mumps worldwide. In Italy, improving routine coverage with two doses of measles, mumps and rubella (MMR) vaccine is one of the key strategies to eliminate measles and rubella. To monitor the effect of the vaccination programme on the population, the surveillance of these vaccine-preventable diseases has been implemented. This provided the opportunity to evaluate the accuracy of the clinical diagnosis of those diseases, including mumps...

BACKGROUND: Epstein-Barr-Virus (EBV) plays an important role as trigger or cofactor for various autoimmune diseases. In a subset of patients with Chronic Fatigue Syndrome (CFS) disease starts with infectious mononucleosis as late primary EBV-infection, whereby altered levels of EBV-specific antibodies can be observed in another subset of patients. METHODS: We performed a comprehensive mapping of the IgG response against EBV comparing 50 healthy controls with 92 CFS patients using a microarray platform...

Lytic infection by the Epstein-Barr virus (EBV) poses numerous health risks, such as infectious mononucleosis and lymphoproliferative disorder. Proteins in the bromodomain and extraterminal (BET) family regulate multiple stages of viral life cycles and provide promising intervention targets. Synthetic small molecules can bind to the bromodomains and disrupt function by preventing recognition of acetylated lysine substrates. We demonstrate that JQ1 and other BET inhibitors block two different steps in the sequential cascade of the EBV lytic cycle...

EBV infection causes mononucleosis and is associated with specific subsets of B cell lymphomas. Immunosuppressed patients such as organ transplant recipients are particularly susceptible to EBV-induced lymphoproliferative disease (LPD), which can be fatal. Leflunomide (a drug used to treat rheumatoid arthritis) and its active metabolite teriflunomide (used to treat multiple sclerosis) inhibit de novo pyrimidine synthesis by targeting the cellular dihydroorotate dehydrogenase, thereby decreasing T cell proliferation...

Epstein-Barr virus (EBV) replication contributes to multiple human diseases, including infectious mononucleosis, nasopharyngeal carcinoma, B cell lymphomas, and oral hairy leukoplakia. We performed systematic quantitative analyses of temporal changes in host and EBV proteins during lytic replication to gain insights into virus-host interactions, using conditional Burkitt lymphoma models of type I and II EBV infection. We quantified profiles of >8,000 cellular and 69 EBV proteins, including >500 plasma membrane proteins, providing temporal views of the lytic B cell proteome and EBV virome...
