Characterization of astrocyte-derived EVs and microglia uptake

What This Experiment Tests

Exploratory experiment designed to discover new patterns targeting CD9 in TIGER mice cortical astrocytes and microglia. Primary outcome: EV uptake by microglia following intraventricular injection

Description

Cortical astrocytes from TIGER mice were shown to release approximately 136 nm extracellular vesicles containing CD9. These EVs were injected intraventricularly and their uptake was studied. CD11b/IBA1 positive microglia surrounding the lateral ventricles were found to take up the injected EVs, demonstrating the transfer of astrocyte-derived EVs to microglia in the brain. This experiment provided evidence for intercellular communication via EVs between astrocytes and microglia in the central nervous system.
