Summary
Epstein-Barr virus (EBV)-associated T/NK-cell neoplasms share genetic alterations, but effective treatments are limited. Further research into molecular subtypes and large cohorts is crucial for developing precision therapies.
Area of Science:
- Hematology
- Oncology
- Virology
Background:
- Epstein-Barr virus (EBV) drives a range of T- and natural killer (NK)-cell neoplasms, from chronic disorders to aggressive lymphomas.
- These neoplasms exhibit a spectrum of clinical presentations and include extranodal NK/T-cell lymphoma (ENKTL) and aggressive NK-cell leukemia.
Purpose of the Study:
- To explore the continuum of EBV-associated T/NK-cell neoplasms.
- To identify shared host genetic alterations and understand EBV's role in oncogenesis.
- To highlight the need for improved therapeutic strategies.
Main Methods:
- Genomic and epigenetic analyses of EBV-associated neoplasms.
- Review of existing literature on disease spectrum and genetic alterations.
- Analysis of viral gene expression in oncogenesis.
Main Results:
- Shared host genetic alterations in JAK-STAT signaling, epigenetic regulators, TP53, and DDX3X are identified across EBV-associated T/NK-cell neoplasms.
- Defective EBV influences viral gene expression, contributing to cancer development.
- Current treatments like l-asparaginase-based chemoradiotherapy show promise for early-stage ENKTL but are insufficient for advanced disease.
Conclusions:
- EBV-associated T/NK-cell neoplasms represent a continuum driven by host genetic alterations and viral factors.
- Effective treatments for advanced-stage disease and other EBV-driven neoplasms are urgently needed.
- Molecular subclassifications and prospective studies are essential for advancing precision therapeutic strategies.

6.5K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
