Overview
This article describes a method for generating Epstein-Barr virus transformed lymphoblast cell lines from human B cells. It also presents an assay to identify B cells likely to undergo transformation within three days post-infection.
Key Study Components
Area of Science
- Virology
- Immunology
- Cancer Biology
Background
- Epstein-Barr virus (EBV) is known for its role in B cell transformation.
- Understanding B cell interactions with EBV is crucial for virology research.
- Lymphoblast cell lines (LCLs) are valuable for various scientific studies.
- Predicting successful transformation can enhance research efficiency.
Purpose of Study
- To provide a reliable method for generating LCLs from human B cells.
- To identify early markers of successful B cell transformation.
- To facilitate research on host-EBV interactions.
Methods Used
- Isolation of peripheral blood mononuclear cells from human blood.
- Infection of cells with Epstein-Barr virus in the presence of immunosuppressive agents.
- Flow cytometry to enumerate CD23 high CD58 positive cells.
- Microscopic observation of cell clusters for transformation assessment.
Main Results
- Successful transformation is indicated by the emergence of CD23 high CD58 positive cells.
- Clusters of lymphoblasts are visible microscopically within a week of infection.
- Feeding and expanding cultures are essential for cryopreservation.
- Early identification of successful transformation can be achieved within three to four days.
Conclusions
- The described protocol allows for efficient generation of LCLs.
- Early prediction of transformation success can streamline research efforts.
- This method contributes valuable insights into B cell biology and EBV interactions.
What is the significance of Epstein-Barr virus in B cell research?
EBV is crucial for studying B cell transformation and its implications in virology and cancer biology.
How can researchers predict successful B cell transformation?
By identifying CD23 high CD58 positive cells as early as three to four days post-infection.
What are lymphoblast cell lines used for?
LCLs are used to study host-pathogen interactions, immune responses, and cancer biology.
What methods are used to isolate B cells?
Peripheral blood mononuclear cells are isolated from human blood using density gradient centrifugation.
How long does it take to see results after infection?
Clusters of transformed cells can be observed microscopically within a week of infection.
