Chronic morphine exposure alters the cargo of brain-derived extracellular vesicles, enhancing neuroplasticity-related proteins.
RNA sequencing revealed upregulation of the ARC gene, important for synaptic plasticity, following morphine treatment.
The study used proteomic analysis, identifying 47 differentially expressed proteins associated with neurodevelopment and addiction pathways.
Findings imply a connection between chronic opioid exposure and neurodegeneration through modifications in extracellular vesicles.
