Tiny bubbles from stem cells help old mouse brains remember better
Intranasal Human NSC‐Derived EVs Therapy Can Restrain Inflammatory Microglial Transcriptome, and NLRP3 and cGAS‐STING Signalling, in Aged Hippocampus

Scientists gave old mice tiny bubbles (called EVs) made from human stem cells through their nose. These bubbles carried special messages that told the brain's immune cells to calm down, fix damaged energy factories, and stop causing inflammation.

Intranasal delivery of extracellular vesicles from stem cells reduces the activity of specific inflammatory pathways and lowers levels of key inflammatory proteins in the hippocampus of aged mice.
Administering extracellular vesicles derived from human stem cells through the nose to aged mice reduces inflammation in the hippocampus and improves cognitive performance by inhibiting specific molecular pathways involved in inflammatory responses.
When aged mice are treated with extracellular vesicles derived from human stem cells through the nose, there is a reduction in brain inflammation markers, lower levels of oxidative stress, increased activity of genes related to mitochondrial function, and improved performance in memory tests.
In older mice, a treatment using tiny particles derived from stem cells, delivered through the nose, reduces specific inflammatory structures in brain immune cells that are linked to neurodegenerative conditions.
In older mice, delivering extracellular vesicles from stem cells through the nose alters gene activity in brain immune cells, increasing expression of genes involved in energy production and stress defense while decreasing expression of genes linked to inflammation.
