Methylene blue stimulates substrate-level phosphorylation catalysed by succinyl-CoA ligase in the citric acid cycle

This study investigated the effects of methylene blue on memory impairment in a rat model of Alzheimer’s disease (AD), focusing on its impact on cytochrome c oxidase (CCO) activity and mitochondrial function. The study found that methylene blue significantly improved spatial memory and increased CCO activity, suggesting enhanced mitochondrial function,

Protective role of methylene blue in Alzheimer’s disease via mitochondria and cytochrome c oxidase

This observational study examined the protective role of methylene blue (MB) in Alzheimer’s disease (AD), demonstrating its potential as a therapeutic agent by enhancing mitochondrial function and acting as an antioxidant. MB improves cellular respiration and ATP production by serving as an alternative electron carrier, reduces oxidative stress, and provides

Methylene blue improves brain oxidative metabolism and memory retention in rats

This study investigated the effects of methylene blue (MB) on brain oxidative metabolism and memory retention in rats. The results showed that MB administration significantly enhanced cytochrome c oxidase activity, which boosted brain oxidative metabolism. Rats treated with MB exhibited a marked improvement in spatial memory retention, with treated rats

Mechanisms and Mitochondrial Redox Signaling in Photobiomodulation

This review explores the mechanisms of photobiomodulation (PBM), a therapy using red or near-infrared light at low power densities to reduce pain, inflammation, and edema while promoting tissue regeneration, including wound healing, bone repair, and tendon recovery. PBM primarily targets cytochrome c oxidase (CCO) in mitochondria, dissociating inhibitory nitric oxide
