ORM2–ZG16 Autophagy in Pancreatic Fibrosis
2026-08-19
This 2026 study identifies ORM2 as an endogenous suppressor of chronic pancreatitis-associated fibrosis and connects its activity to ZG16-dependent autophagy in pancreatic stellate cells. By combining pancreas-specific AAV manipulation, cell models, autophagy flux assays, and protein-interaction analyses, the work defines a mechanistic framework for studying antifibrotic regulation rather than relying on expression correlations alone.

Cholesterol Hinders Lipid Nanoparticle Trafficking
2026-08-19
Luo and colleagues developed a nucleic-acid tracking and high-throughput imaging platform to examine how lipid nanoparticle composition shapes intracellular trafficking. Their results indicate that excess cholesterol promotes aggregation of LNP-containing early endosomes, restricting endolysosomal progression and reducing delivery efficiency, whereas DSPC can mitigate this effect.

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.

HCAR3 Structures Reveal Agonist Selectivity
2026-08-16
The 2025 PLOS Biology study uses cryo-EM and cellular cAMP assays to define how HCAR3 recognizes several agonists and distinguishes them from HCAR2. Its structures identify orthosteric-pocket geometry and residue-level interactions that may guide HCAR3-selective ligand design while helping researchers interpret lipid signaling pathway modulation.
