- 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.
- 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.
- These microRNAs suppress protein systems that drive chronic inflammation and recharge mitochondria in neurons, leading to improved cognitive function.
