Summary

Story summary

Texas A&M researchers developed an experimental intranasal spray that reversed brain-aging markers in animal models after two doses.
The spray delivers extracellular vesicles loaded with microRNAs to brain tissue, bypassing the blood-brain barrier.
It suppresses inflammatory pathways such as the NLRP3 inflammasome and cGAS-STING signaling.
The treatment restores mitochondrial activity and reduces oxidative stress in the animals.
It improves memory and object-recognition, with effects lasting months and consistent across sexes.
