Scientists have developed a new nasal spray that significantly reduces brain inflammation and restores memory in mice. The treatment, requiring only two doses, has effects lasting months and could redefine the understanding of brain ageing.
Breakthrough in Brain Research
Researchers from Texas A&M University suggest this spray could offer a breakthrough for conditions like Alzheimer's disease and aid stroke survivors. The nasal spray works by delivering microscopic biological parcels, called extracellular vesicles, which carry microRNAs directly into brain tissue.
How It Works
These microRNAs suppress protein systems that drive chronic inflammation and recharge mitochondria in neurons, leading to improved cognitive function. In tests on mice, just two doses of the new nasal spray were found to slow brain ageing and restore memory.
The findings could have significant implications for human health, offering a non-invasive method to combat neurodegenerative diseases and age-related cognitive decline.
