Subversion of host immune surveillance is a crucial step in viral pathogenesis. Epstein-Barr virus (EBV) encodes two immune evasion gene products, BCRF1 (viral IL-10) and BPLF1 (deubiquitinase/deneddylase); both proteins suppress antiviral immune responses during primary infection. The BCRF1 and BPLF1 genes are expressed during the late phase of the lytic cycle, an essential but poorly understood phase of viral gene expression. Several late gene regulators recently identified in beta and gamma herpesviruses form a viral pre-initiation complex for transcription...

Aggressive NK-cell leukemia (ANKL) is characterized by systemic infiltration of Epstein-Barr virus (EBV)-associated natural killer cells and poor prognosis. We report a case of ANKL in which EBV-specific cytotoxic T lymphocytes (CTLs) were induced. A 41-year-old male suffered from fever, pancytopenia, and hepatosplenomegaly. The number of abnormal large granular lymphocytes in the bone marrow was increased and the cells were positive for CD56 and EBV-encoded small nuclear RNAs. The patient was diagnosed with ANKL and achieved a complete response following intensive chemotherapy...

Objective: To investigate clinicopathologic characteristics, immunophenotype and EB virus-related molecular genetic alterations in primary central nervous system diffuse large B cell lymphoma (DLBCL) along with correlation with clinical prognosis. Methods: A total of 30 cases of primary central nervous system DLBCL were retrospectively studied by retrieving clinical data, histological evaluation and immunophenotyping by EnVision two steps methods. The expression of EBER mRNA was detected by in situ hybridization and bcl-2, bcl-6 and C-MYC gene abnormalities were analyzed by interphase fluorescence in situ hybridization...

BACKGROUND: Mutant huntingtin (mHTT) is encoded by the Huntington's disease (HD) gene and its accumulation in the brain contributes to HD pathogenesis. Reducing mHTT levels through activation of the autophagosome-lysosomal pathway may have therapeutic benefit. Transcription factor EB (TFEB) regulates lysosome biogenesis and autophagy. OBJECTIVE: To examine if increasing TFEB protein levels in HD mouse striatum induces autophagy and influences mHTT levels. METHODS: We introduced cDNA encoding TFEB with an HA tag (TFEB-HA) under the control of neuron specific synapsin 1 promoter into the striatum of 3 month old HDQ175/Q7 mice using adeno-associated virus AAV2/9...

Epstein-Barr virus (EBV) is a human oncogenic herpesvirus associated with lymphoma and nasopharyngeal carcinoma. Because the susceptible hosts of EB virus are limited to human and cotton-top tamarins (Saguinus oedipus), there have been no appropriate animal models until the lymphoma model induced by EBV in human peripheral blood lymphocyte (hu-PBL)/SCID chimeric mice was reported. However, it is still controversial whether the EBV-associated lymphoma induced in hu-PBL/SCID mice is a monoclonal tumor. In this study, we transplanted normal human peripheral blood lymphocytes (hu-PBL) from six donors infected with EBV into SCID mice to construct hu-PBL/SCID chimeric mice...

OBJECTIVE: This study aimed to map differences in extension patterns between adenoid cystic carcinoma (ACC) of the nasopharynxandnasopharyngeal carcinomaon magnetic resonance imaging (MRI) and provide more information for treatments. METHODS: MRI examinations and clinical records were reviewed in 18 patients with ACC of the nasopharynx and 182 patients with nasopharyngeal carcinoma (NPC). All patients had biopsy to confirm diagnosis. Differences between NPC and ACC in terms of extension patterns were identified by the retrospective analysis of images from patients undergoing MRI...

We report a rare case of T cell type monomorphic post-transplant lymphoproliferative disorders (PTLD) after autologous stem cell transplantation. A 53-year-old man with multiple myeloma received autologous stem cell transplantation and achieved a very good partial response. Nine months later, he developed a high fever and consciousness disturbance, and had multiple swollen lymph nodes and a high titer of Epstein-Barr (EB) virus DNA in his peripheral blood. Neither CT nor MRI of the brain revealed any abnormalities...

BACKGROUND: Epstein-Barr virus (EBV) is associated with a subset of gastric carcinoma which was defined as EBV associated gastric carcinoma (EBVaGC). The proportion of EBVaGC in gastric remnant carcinoma (GRC) which occurs in the intact stomach five or more years after gastric surgery for benign disease is significantly higher than that in conventional gastric carcinoma (CGC). The infection of EBV in recurrent gastric carcinoma (RGC) with local anastomotic recurrence is poorly understood...

A 70-year-old male visited our hospital due to failure of pneumonia treatment. Chest CT showed consolidation in the right middle field and slight mediastinal lymphadenopathy in the subcarinal region. Lung consolidation improved with antibiotics; subcarinal lymphadenopathy progressed after four months. Malignant lymphoma was suspected given elevated sIL2-R levels (1862 U/ml). Patchy ground glass opacities appeared in the bilateral lung field just before surgical biopsy. He was diagnosed with IgG4-related lung disease after inspection of a pathological specimen obtained from the right upper lung and right hilar lymph node...

The derivation of pluripotent stem cells from human embryos and the generation of induced pluripotent stem cells (iPSCs) from somatic cells opened a new chapter in studies on the regeneration of the post-infarction heart and regenerative medicine as a whole. Thus, protocols for obtaining iPSCs were enthusiastically adopted and widely used for further experiments on cardiac differentiation. iPSC-mediated cardiomyocytes (iPSC-CMs) under in vitro culture conditions are generated by simulating natural cardiomyogenesis and involve the wingless-type mouse mammary tumour virus integration site family (WNT), transforming growth factor beta (TGF-β) and fibroblast growth factor (FGF) signalling pathways...

OBJECTIVE: Severe Epstein-Barr (EB) virus infection is potentially a devastating process that often leads to death encountered in pediatrics recently. Inappropriate control of EB virus replication may cause severe infection resulting in multiple organ dysfunction. However, little information is available on pulmonary complications associated with EB virus infection. The aim of the present study was to investigate severe EB virus (EBV) infection complicated with lung injury in pediatric intensive care unit (PICU), including clinical characteristics, laboratory or imaging feature and outcomes...
