Exploratory experiment designed to discover new patterns targeting P2rx7 in Brain-derived extracellular vesicles from PS19 mice. Primary outcome: EV protein cargo composition, particularly tau and mitochondrial proteins
This experiment analyzed the protein cargo of brain-derived extracellular vesicles (BDEVs) from PS19 mice with and without P2rx7 expression to determine how P2RX7 affects EV cargo loading. Researchers isolated extracellular vesicles from brain tissue and performed proteomic analysis to identify and quantify proteins enriched in EVs, with particular focus on tau and mitochondrial proteins. The study likely involved EV isolation using ultracentrifugation or other purification methods, followed by mass spectrometry-based proteomics. Single-molecule super-resolution microscopy was used to validate findings about tau and mitochondrial protein loading in EVs.
