Endoplasmic reticulum (ER) stress plays a crucial role in the pathogenesis of neuroinflammation and chronic pain. Herein, we hypothesized that PRKR-like endoplasmic reticulum kinase (PERK) and Inositol-requiring enzyme type 1 (IRE1) regulate Lipocalin-2 (LCN2) and Nod-like receptor family pyrin domain containing 3 (NLRP3) expression in astrocytes, thereby contributing to morphine tolerance and hyperalgesia.
