Epstein Barr virus (EBV)-encoded nuclear antigen-1 (EBNA1) plays a pivotal in an EBV episome replication and persistence. Despite considerable attempts, there are no EBV drugs or vaccines. We attempted to eradicate EBV episomes by targeting EBNA1 using the transcription activator-like effector nucleases (TALEN) (E1TN). E1TN-mediated transient knockout (KO) of EBNA1 reduced EBNA1 expression, and...
Epstein-Barr virus (EBV)-specific cytotoxic T lymphocytes are considered pivotal to prevent lymphoproliferative disease (LPD) in allogeneic stem cell transplantation (SCT) recipients. We evaluated the recovery of EBV-specific CD8+ T cells after partially T-cell-depleted SCT and studied the interaction between EBV-specific CD8+ T cells, EBV reactivation, and EBV-LPD. EBV-specific CD8+ T cells we...
The Epstein-Barr virus (EBV) is detected in the tissue of about 10% of gastric carcinoma cases throughout the world. In each case, 100% of carcinoma cells are infected with EBV. Analysis of EBV in carcinoma biopsies indicates that carcinoma is formed by the proliferation of a single EBV infected cell. These findings suggest that EBV plays an important role in the development of EBV positive gas...
به منظور بررسی و شناسایی همزمان چهار ویروس مهم سیب زمینی طی تابستان 1386تعداد 435 نمونه از غده های 32 مزرعه سیب زمینی واقع در شهرستانهای استان خراسان رضوی به صورت تصادفی جمع آوری شد. سپس جوانه های هرغده با آزمونdas- elisa مورد بررسی قرار گرفتند و مشخص گردید 76 نمونه به pvy، 47 نمونه به plrv، 44 نمونه به pva و 13 نمونه آلوده به pvx بودند. نتایج نشان داد که آلودگی همزمان فقط در25نمونه وجود داشت ک...
Introduction: Epstein – Barr virus (EBV) is a herpesvirus which establishes a persistent life-long infection in over 95% of adults world wide. Infection is usually asymptomatic but the virus is associated with a variety of disease, including nasopharyngeal carcinoma (NPC), Burkitt’s lymphoma (BL), Multiple sclerosis MS, EBV-associated B-cell lymphoproliferative disease (BLPD), Hodgkin and non...
Epstein-Barr virus (EBV) infection is closely associated with undifferentiated nasopharyngeal carcinoma (NPC), strongly implicating a role for EBV in NPC pathogenesis; conversely, EBV infection is rarely detected in normal nasopharyngeal epithelial tissues. In general, EBV does not show a strong tropism for infecting human epithelial cells, and EBV infection in oropharyngeal epithelial cells is...
Adoptive immunotherapy with EBV-specific CTL (EBV-CTL) effectively prevents and treats EBV-driven lymphoproliferation in immunocompromised hosts. EBV-seronegative solid organ transplant recipients are at high risk of EBV-driven lymphoproliferation because they lack EBV-specific memory T cells. For the same reason, standard techniques for generating EBV-CTL in vitro from EBV-naive individuals ar...
Epstein-Barr virus (EBV) belongs to the family of herpesviruses (herpes type 4) and is one most common highly contagious. During pandemic a new coronavirus disease, it was found that in patients previously infected with EBV, COVID-19 can cause its reactivation, which often manifested by clinic acute hepatitis. The article presents clinical case development hepatitis patient mixed infection EBV ...
Gastric carcinoma (GC) is a leading cause of mortality. 10% of GC cases are related with EBV (Epstein-Barr virus) infection. The detailed mechanistic roles EBV genes play and especially the interaction between the viral genes and human genes in GC remain unclear. In this study, raw fastq data from 285 GC samples were downloaded from TCGA (The Cancer Genome Atlas), including 25 EBV positive (EBV...
