## Mechanistic Overview
P2RX7-Mediated Exosome Secretion Blockade starts from the claim that modulating P2RX7 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "# P2RX7-Mediated Exosome Secretion Blockade: A Therapeutic Target in Neurodegeneration ## Mechanism of Action P2RX7 (purinergic receptor P2X, ligand-gated ion channel 7) is a ATP-gated non-selective cation channel expressed predominantly on microglia, the resident imm
This hypothesis proposes that age-related TREM2 signaling dysfunction drives microglia into a senescent state that fundamentally rewires astrocyte-microglia communication networks, creating a pathological feedback loop in neurodegeneration. Under normal conditions, TREM2/TYROBP signaling maintains microglial homeostasis and supports neuroprotective astrocyte-microglia cross-talk through regulated release of IL-33, lactate, and ATP. However, during aging, accumulated DNA damage and metabolic stre
