Nasal Spray Breakthrough Could Reverse Brain Ageing

In an innovative breakthrough, scientists at Texas A&M University have developed a nasal spray containing microRNAs aimed at reversing brain ageing. The study, published in the Journal of Extracellular Vesicles, has shown promising results in suppressing neuroinflammation and significantly improving memory in laboratory mice.

The nasal spray therapy, which involves two doses, helps restore the mitochondria—often referred to as the brain cells' power plants—and leads to improvements in cognitive function. Researchers highlight its potential in combating age-related diseases such as dementia without the need for invasive brain surgery.

By targeting the NLRP3 inflammasome and the cGAS-STING signalling pathways, the nasal spray notably reduces oxidative stress and neuroinflammaging. These findings suggest a possible future where age-related brain decline and diseases like Alzheimer's could be effectively treated using this non-invasive method.
