Proteomic Characterization of Human Peripheral Blood Mononuclear Cells Exposed to a 50 Hz Magnetic Field
This in vitro study compared proteomic profiles of PBMCs from three human donors after 24-hour exposure to a 50 Hz, 1 mT extremely low-frequency magnetic field versus unexposed cells. The abstract reports broad protein expression changes, including upregulation of proteins associated with metabolic processes and downregulation of proteins linked to T cell costimulation/activation and immune processes. No effects were observed on cell proliferation, viability, or cell cycle progression. The authors interpret the proteomic shifts as metabolic reprogramming with potential implications for immune regulation.
Key points
- PBMCs from three human subjects were exposed in vitro to a 50 Hz, 1 mT magnetic field for 24 hours and compared with unexposed controls from the same individuals.
- The abstract reports altered expression of multiple proteins following ELF-MF exposure.
- No effects were observed on PBMC proliferation, viability, or cell cycle progression under the studied conditions.
- Fifty-one proteins were reported as upregulated, with many associated with cellular metabolic processes.
- SLC25A4, involved in mitochondrial energy exchange, was consistently upregulated.
- Sixty-seven proteins were reported as downregulated, many linked to T cell costimulation/activation and immune system processes.
- The authors conclude the pattern reflects metabolic reprogramming alongside reduced expression of immune-activation-related proteins.
