NLRP3-Driven Astrocyte Plasticity in Morphine Tolerance
2026-08-18
Yuan et al. link spinal NLRP3 inflammasome activation with a shift toward the neurotoxic A1 astrocyte phenotype during morphine tolerance. Their pharmacological intervention study suggests that MCC950 can slow tolerance development while normalizing inflammatory and astrocyte-state markers, although cell-specific causality remains unresolved.

PreScission Protease (PSP): Tag Cleavage Guide
2026-08-17
PreScission Protease (PSP) is an HRV 3C protease-based enzyme for removing recombinant fusion tags at a defined Gln-Gly bond during protein purification. It is best suited to constructs containing the specified cleavage sequence and workflows that can maintain approximately 4 °C conditions; it should not be assumed effective for substrates lacking an accessible site or for processes requiring unvalidated temperatures.
