An Efficient and Simple Method to Establish NK and T Cell Lines from Patients with Chronic Active Epstein-Barr Virus Infection

[The spectrum of infections caused by the Epstein-Barr virus]
Abstract:
The observation by Epstein and Barr (EB) of virus particles in Burkitt lymphoma cells in 1964 led 4 years later to the discovery that this virus was the long sought agent responsible for infectious mononucleosis. Pathophysiologically the EB virus specifically infects B lymphocytes of the immune system and induces perpetual multiplication of these cells if infection remains uncontrolled. The T lymphocytes, once sensitized against these virus infected cells, either kill them or suppress their continuous growth. During acute infectious mononucleosis, these stimulated T cells appear in the bloodstream as "atypical lymphocytes". If cell-mediated immunity is hampered by either congenital or acquired immunodeficiency the proliferative potential of EBV infected B lymphocytes may become uncontrolled and lead either to fulminant and lethal infectious mononucleosis or to polyclonal or monoclonal B cell proliferation. This later phenomenon appears to be the source of most of the lymphoma observed in transplant patients who are chronically immunosuppressed. Much remains to be understood of the mechanisms of EBV infections, which in some geographic areas lead to inapparent infections and in others to Burkitt lymphoma or nasopharyngeal carcinoma, while in temperate regions the clinical manifestations are those of infectious mononucleosis.
Insights
Epstein-Barr virus (EBV) infects B lymphocytes, potentially causing uncontrolled proliferation. Immune responses control EBV, but immunodeficiency can lead to severe illness or cancers like lymphoma.
Area of Science:
- Virology
- Immunology
- Oncology
Context:
- Epstein-Barr virus (EBV) identified in Burkitt lymphoma cells in 1964.
- EBV confirmed as the cause of infectious mononucleosis in 1968.
- EBV specifically targets B lymphocytes, crucial immune cells.
Purpose:
- To elucidate the pathogenic mechanisms of Epstein-Barr virus (EBV) infection.
- To understand the interplay between EBV, B lymphocytes, and T lymphocytes.
- To explore EBV's role in various clinical manifestations, including infectious mononucleosis and lymphomas.
Summary:
- EBV infects B lymphocytes, inducing uncontrolled proliferation if the immune system cannot control it.
- T lymphocytes combat EBV-infected cells, with stimulated T cells appearing as 'atypical lymphocytes' during acute infectious mononucleosis.
- Immunodeficiency compromises cell-mediated immunity, increasing risks of lethal infectious mononucleosis or B cell lymphomas.
Impact:
- Highlights the critical role of cell-mediated immunity in controlling EBV.
- Explains the link between EBV, immunosuppression, and lymphomagenesis in transplant patients.
- Underscores the diverse geographic and clinical outcomes of EBV infection, from asymptomatic cases to specific cancers.
