Release of infectious Epstein-Barr virus by transformed marmoset leukocytes
Abstract:
Marmoset blood leukocytes transformed in vitro by Epstein-Barr virus regularly release extracellular infectious Epstein-Barr virus with high titers of transforming activity. By comparison, human umbilical cord leukocytes and adult human leukocytes transformed by Epstein-Barr virus release either no extracellular infectious virus or small amounts, irregularly.
Insights
Marmoset leukocytes infected with Epstein-Barr virus consistently release infectious virus. Human leukocytes release significantly less infectious Epstein-Barr virus after transformation.
Area of Science:
- Virology
- Immunology
- Cell Biology
Background:
- Epstein-Barr virus (EBV) is a human herpesvirus known to infect and transform B lymphocytes.
- Understanding the in vitro transformation process and viral shedding is crucial for studying EBV pathogenesis.
Purpose of the Study:
- To compare the release of infectious Epstein-Barr virus from transformed marmoset leukocytes versus human leukocytes.
- To investigate differences in viral shedding patterns between primate species post-EBV transformation.
Main Methods:
- In vitro transformation of marmoset, human umbilical cord, and adult human leukocytes using Epstein-Barr virus.
- Quantification of extracellular infectious Epstein-Barr virus titers released from transformed cell cultures.
Main Results:
- Marmoset blood leukocytes consistently released high titers of infectious Epstein-Barr virus after in vitro transformation.
- Human umbilical cord and adult human leukocytes released minimal or no infectious Epstein-Barr virus irregularly after transformation.
Conclusions:
- Marmoset leukocytes serve as a more productive model for studying Epstein-Barr virus replication and shedding post-transformation.
- Species-specific differences exist in the ability of leukocytes to release infectious Epstein-Barr virus following in vitro transformation.
