Human B cell immortalization is crucial for developing antibody drugs and diagnostics. This review covers methods like EBV transformation and CD40 activation for producing therapeutic monoclonal antibodies (mAbs).
Area of Science:
- Biotechnology
- Immunology
- Cell Biology
Background:
- Human B cell immortalization is essential for in vitro maintenance of growth and antibody production.
- This technology is vital for developing antibody-based drugs and diagnostics for various human diseases.
Purpose of the Study:
- To review the research progress, methods, and future directions of human B cell immortalization.
- To highlight its significance as a powerful tool for monoclonal antibody preparation.
Main Methods:
- Epstein-Barr virus (EBV) transformation
- Simian virus 40 (SV40) virus infection
- In vitro genetic modification
- CD40 activation
Main Results:
- Immortalized human B cells efficiently produce monoclonal antibodies (mAbs).
- These mAbs can overcome immune rejection associated with heterologous antibodies.
- Over 100 mAbs have been FDA-approved for treating cancer, autoimmune diseases, and infectious diseases.
Conclusions:
- Human B cell immortalization is a key technology for advancing monoclonal antibody development.
- Continued research into immortalization methods will drive innovation in biotherapeutics and diagnostics.
