QuantiFERON-EBV RUO helps researchers understand Epstein-Barr virus (EBV) infection and related malignancies, providing a dynamic view of the host immune response // Advancing research in oncology and autoimmune diseases by measuring T cell responses to EBV, providing Valuable information provides insight into the role of viruses in these conditions // Further expanding QuantiFERON’s cell-mediated immune response testing portfolio beyond TB
VENLO, the Netherlands, Oct. 4, 2023 (GLOBE NEWSWIRE) — QIAGEN (NYSE: QGEN; Frankfurt Prime Standard: QIA) today announced the launch of its QuantiFERON-EBV RUO (Research Use Only) assay. Various epidemiological studies estimate that Epstein-Barr virus (EBV), or human herpesvirus type 4, is positive in more than 90% of the global population and is an important pathogen in organ transplant recipients.
This new addition to the QuantiFERON assay portfolio is designed to support the study of EBV infection and EBV-associated malignancies by utilizing highly specific EBV antigens to stimulate cell-mediated immune responses, thereby providing a dynamic view of host-virus active immune interactions. .
EBV is implicated in diseases ranging from infectious mononucleosis to EBV-associated tumors and tumor-like lesions. In organ transplant recipients, EBV is associated with posttransplant lymphoproliferative disease (PTLD), a potentially fatal complication after solid organ transplantation. It is estimated that more than 80% of PTLD cases in Europe and the United States are related to EBV. (1)
Additionally, there is growing evidence of a potential link between EBV and multiple sclerosis (MS), a chronic disease of the central nervous system estimated to affect more than 2.8 million people worldwide. EBV T cell measurements in MS may have a potential role in understanding disease progression, treatment monitoring, and developing customized treatments. (2)
“The QuantiFERON-EBV RUO test represents a major advance in our understanding of the complex relationship between EBV and the immune system,” said Jean-Pascal Viola, senior vice president and head of the Molecular Diagnostics business area at QIAGEN. “This test opens the door to innovative research. opens the door to delivering insights that can revolutionize patient care by guiding customized treatments across various areas of medicine, including oncology and autoimmune diseases.”
T cells play a crucial role in controlling and eliminating the virus, and an effective T cell response helps determine the course and severity of EBV infection. Measuring T cell responses to EBV can help researchers better understand the immune response to the virus. Specifically, in transplant patients, it has the potential to personalize immunosuppressive therapy, stratify the risk of EBV-induced disease, assist clinicians in tailoring the timing of testing and monitoring, and assess the efficiency and durability of future EBV vaccines.
QuantiFERON-EBV RUO uses a combination of CD4+ and CD8+ antigens specific for the EBV nuclear antigen protein to stimulate lymphocytes in heparinized whole blood. This approach is different but complementary to traditional testing, which focuses on detecting viral DNA or antibodies produced in response to the virus.
Growing Portfolio of QuantiFERON Cell-Mediated Immune Response Tests
The new assay adds to QuantiFERON’s growing portfolio of cell-mediated immune response tests. QuantiFERON-TB Gold Plus is the world’s leading IGRA blood test, performing millions of TB tests every year. QuantiFERON SARS-CoV-2 identifies immune responses to COVID-19, and QuantiFERON-CMV is an indirect test for cytomegalovirus infection in transplant patients. The QuantiFERON monitor assesses non-pathogen-specific cell-mediated immune responses in transplant patients. In addition, QIAGEN and DiaSorin collaborated to develop the LIAISON LymeDetect test, which uses QuantiFERON technology to detect early-stage Lyme Borrelia infection. (3)
QIAGEN’s QuantiFERON technology is a unique method for detecting cell-mediated immune responses from whole blood samples. It works by identifying specific T cells in individuals who have been exposed to infectious pathogens. When infection-specific antigens bind to the blood, antigen-specific T cells are rapidly re-stimulated, resulting in the secretion of interferon-gamma (IFN-γ), which can be measured as a marker of immune response. Testing includes QuantiFERON blood collection tubes using its proprietary stimulation principle and the QuantiFERON ELISA detection system to measure interferon-gamma production.
