HBsAg Hijacks TBK1 to Suppress IFN and Induce Autophagy
2026-08-17
The reference study identifies a mechanism by which hepatitis B surface antigen redirects TBK1 signaling away from IRF3-dependent type I interferon production and toward p62-associated autophagy. Its combination of molecular interaction studies, pharmacological perturbation, animal models, and human liver samples connects incomplete autophagy with HBV persistence and provides a framework for studying viral immune evasion.

Quercetin, Hippo Signaling, and Cataract Protection
2026-08-17
A 2025 study integrates network pharmacology, UVB-induced cataract modeling, and hydrogen peroxide-injured lens epithelial cells to examine how quercetin may protect the lens through Hippo pathway modulation. Its findings link reduced oxidative stress and improved epithelial-cell survival with lower Hippo signaling activity, while pathway reactivation with α-hederin weakened these effects.

S Tag Peptide: Workflow, QC, and Troubleshooting
2026-08-11
S Tag Peptide supports recombinant protein detection, antibody-based purification, and protein solubility improvement when encoded as an N- or C-terminal S-peptide fusion tag. It is appropriate for aqueous protein expression and purification workflows, but the free peptide is not a standalone ribonuclease reagent, is insoluble in ethanol, and should not be stored long term in solution.
