Repeated electromagnetic field stimulation lowers amyloid-β peptide levels in primary human mixed brain tissue cultures
Abstract
Overview
Late Onset Alzheimer's Disease is the most common cause of dementia, characterized by the accumulation of neurotoxic plaques primarily consisting of amyloid-β (Aβ) peptide and tau protein tangles.
Findings
- Data supports the use of repeated electromagnetic field stimulation (REMFS) as a noninvasive approach to decrease Aβ levels in primary human brain cultures.
- Effects of REMFS were tested on Aβ levels in varying lengths (Aβ40 and Aβ42) under different electromagnetic frequencies, powers, and specific absorption rates (SAR).
- Significant reduction in Aβ levels was observed in cultures treated at 64 MHz, for 1-2 hours daily across several timeframes, with a minimum effective SAR of 0.4 W/kg.
- No evident cellular toxicity or significant alterations in secreted amyloid precursor protein-α (sAPPα) levels were noted, indicating that reduction of Aβ levels was not due to a shift towards the α-secretase pathway.
Conclusion
The REMFS parameters used are similar to those employed in human MRI, suggesting potential for clinical application to modulate neurodegenerative plaque deposition.
