differential requirement for p2x7r function in il-17 dependent vs. il-17 independent cellular immune responses. | il17-dependent autoimmunity to collagen type v (col v) has been associated with lung transplant obliterative bronchiolitis. unlike the t helper 1 (th1)-dependent immune responses to tetanus toxoid (tt), the th17 response to col v in lung transplant patients and its th1/17 variant observed in coronary artery disease patients requires il-1β, tumor necrosis factor α and cd14(+) cells. given the involvement of the p2x7 receptor (p2x7r) in monocyte il-1β responses, we investigated its role in th17-, ... | 2014 | 24866539 |
utility of quantitative ebv dna measurements in cerebrospinal fluid for diagnosis and monitoring of treatment of central nervous system ebv-associated post-transplant lymphoproliferative disorder after allogenic hematopoietic stem cell transplantation. | epstein-barr virus (ebv)-associated post-transplant lymphoproliferative disorder (ptld) after hematopoietic stem cell transplantation (hsct) is a rare but life- threatening condition. despite routine ebv dna-emia monitoring in blood, central nervous system involvement of the disease is still associated with diagnostic difficulties and poor outcome. | 2014 | 24866354 |
virus-encoded micrornas facilitate gammaherpesvirus latency and pathogenesis in vivo. | gammaherpesviruses, including epstein-barr virus (ebv), kaposi sarcoma-associated herpesvirus (kshv, or hhv-8), and murine gammaherpesvirus 68 (mhv68, γhv68, or muhv-4), are b cell-tropic pathogens that each encode at least 12 micrornas (mirnas). it is predicted that these regulatory rnas facilitate infection by suppressing host target genes involved in a wide range of key cellular pathways. however, the precise contribution that gammaherpesvirus mirnas make to viral life cycle and pathogenesis ... | 2014 | 24865551 |
epstein-barr virus as a paradigm in nasopharyngeal cancer: from lab to clinic. | nasopharyngeal carcinoma (npc) of the undifferentiated subtype remains endemic in southern china, with a peak incidence in this region approaching 30 cases per 100,000 population per year. despite advances in chemotherapy and radiation delivery techniques in localized disease, distant metastasis is still common and npc remains the seventh leading cause of cancer death in the region. there is great need for early diagnosis, developing novel therapies, and identifying patients with localized disea ... | 2014 | 24857071 |
virus and autoantigen-specific cd4+ t cells are key effectors in a scid mouse model of ebv-associated post-transplant lymphoproliferative disorders. | polyclonal epstein-barr virus (ebv)-infected b cell line (lymphoblastoid cell lines; lcl)-stimulated t-cell preparations have been successfully used to treat ebv-positive post-transplant lymphoproliferative disorders (ptld) in transplant recipients, but function and specificity of the cd4+ component are still poorly defined. here, we assessed the tumor-protective potential of different cd4+ t-cell specificities in a ptld-scid mouse model. injection of different virus-specific cd4+ t-cell clones ... | 2014 | 24853673 |
detection of a specific biomarker for epstein-barr virus using a polymer-based genosensor. | this paper describes methodology for direct and indirect detections of a specific oligonucleotide for epstein-barr virus (ebv) using electrochemical techniques. the sequence of oligonucleotide probe (ebv1) revealed a high sequence identity (100%) with the ebv genome. for the development of the genosensor, ebv1 was grafted to the platform sensitized with poly(4-aminothiophenol). after that, the hybridization reaction was carried out with the complementary target (ebv2) on the modified electrode s ... | 2014 | 24853286 |
epstein-barr virus-positive nodular lymphocyte predominant hodgkin lymphoma. | hodgkin lymphoma (hl) is classified into 2 largely distinct subgroups, namely nodular lymphocyte predominant hl (nlphl) and classic hl (chl). chl is further divided into nodular sclerosis, lymphocyte-rich, mixed cellularity (mcchl) and lymphocyte-depleted (ldchl) subtypes. in industrialized nations, epstein-barr virus (ebv) has been associated with all types of chl, especially the mcchl and ldchl subtypes, but is rare in nlphl. we report 8 cases of ebv-positive nlphl occurring in patients in the ... | 2014 | 24852241 |
a single amino acid in ebna-2 determines superior b lymphoblastoid cell line growth maintenance by epstein-barr virus type 1 ebna-2. | sequence differences in the ebna-2 protein mediate the superior ability of type 1 epstein-barr virus (ebv) to transform human b cells into lymphoblastoid cell lines compared to that of type 2 ebv. here we show that changing a single amino acid (s442d) from serine in type 2 ebna-2 to the aspartate found in type 1 ebna-2 confers a type 1 growth phenotype in a lymphoblastoid cell line growth maintenance assay. this amino acid lies in the transactivation domain of ebna-2, and the s442d change increa ... | 2014 | 24850736 |
epstein-barr virus serology as a potential screening marker for nasopharyngeal carcinoma among high-risk individuals from multiplex families in taiwan. | nasopharyngeal carcinoma (npc) is an epstein-barr virus (ebv)-associated cancer that is highly treatable when diagnosed early, with 5-year disease-free survival of approximately 90%. however, npc is typically diagnosed at advanced stages, in which disease-free survival is <50%. there is, therefore, a need for clinical tools to assist in early npc detection, particularly among high-risk individuals. | 2014 | 24769890 |
arid1a/baf250a as a prognostic marker for gastric carcinoma: a study of 2 cohorts. | arid1a/baf250a has been recently implicated as a tumor suppressor in gastric cancer. we sought to clarify the clinical significance of baf250a/arid1a in relation to other clinical parameters and relevant biomarkers in gastric carcinoma. cases from 2 separate cohorts of patients with gastric carcinoma from vancouver (n = 173) and toronto (n = 80) were selected for the construction of tissue microarrays, which were used to assess the immunohistochemical status of baf250a (anti-arid1a), mismatch re ... | 2014 | 24767857 |
