Establishment of continuous multiple sclerosis brain cultures after transformation with PML-SV40 virus
Abstract:
PML-SV40 virus was used to transform cells from explants and monolayer subcultures of human brain derived from biopsies or autopsies of MS cases, as well as from 1 case of Jakob-Creutzfeldt disease (JC), 1 case of amyotrophic lateral sclerosis (ALS) and several cases without CNS disease. The success of transformation depended on the growth condition of the culture at the time of infection but at present at least 14 cell lines, 10 derived from MS, 2 from JC, 1 from ALS and 1 from a normal non-CNS patient are maintained in continuous culture.
Insights
Researchers used the PML-SV40 virus to transform human brain cells from patients with multiple sclerosis (MS), Jakob-Creutzfeldt disease (JC), and amyotrophic lateral sclerosis (ALS). This resulted in 14 continuously cultured cell lines for further study.
Area of Science:
- Neuroscience
- Virology
- Cell Biology
Background:
- Human brain cells are crucial for studying neurological diseases.
- Cell cultures provide a model for investigating disease mechanisms.
- Viral transformation can immortalize cells for long-term study.
Purpose of the Study:
- To establish continuously cultured human brain cell lines from various neurological conditions.
- To investigate the potential of PML-SV40 virus for cell transformation in neurological disease research.
Main Methods:
- Utilized the PML-SV40 virus for cell transformation.
- Infected explants and monolayer subcultures of human brain cells.
- Cultured cells derived from multiple sclerosis (MS), Jakob-Creutzfeldt disease (JC), amyotrophic lateral sclerosis (ALS), and non-CNS cases.
- Maintained cell lines in continuous culture.
Main Results:
- Successfully transformed human brain cells using PML-SV40 virus.
- Established 14 distinct cell lines in continuous culture.
- Derived 10 cell lines from MS cases, 2 from JC, 1 from ALS, and 1 from a normal control.
- Transformation success was dependent on cell culture growth conditions at infection.
Conclusions:
- PML-SV40 virus can effectively transform human brain cells from various neurological disease patients.
- The established cell lines offer valuable resources for studying MS, JC, and ALS.
- Cell culture conditions play a critical role in viral transformation efficiency.
