Increases in extracellular K + mediated by neuronal activities, along with vasoconstrictors such as endothelin 1 (ET1), PDGFB, and blood-derived insulin-like growth factor 1 (IGF1), trigger Ca 2+ entry into pericytes through VGCCs, causing depolarization and contraction [7, 93]
IV delivery bypasses this entirely, achieving near 100% bioavailability and distributing glutathione directly to tissues
