Cold Atmospheric Plasma for Alzheimer’s disease

Lightning has been proposed as a pivotal energy source driving prebiotic chemical evolution and early life processes. Similarly, external physical stimuli such as sound and light have been shown to modulate neurophysiological activity and mitigate Alzheimer’s disease (AD) pathology by promoting amyloid-β (Aβ) clearance. Here, we demonstrate that cold atmospheric plasma (CAP) acts as a joule-level analog of lightning, integrating light, sound, and reactive species to modulate AD progression in a mouse model. Using multimodal analyses, we show that CAP treatment enhances key neuroimmune signaling pathways in an AD murine model, including microglial activation, without inducing pathological alterations at the functional, transcriptomic, or proteomic levels in healthy mice. These findings highlight CAP as a safe and efficacious modality for modulating neurodegenerative processes, establishing a foundation for its therapeutic translation in AD and related disorders.
