HBsAg Rewires TBK1 to Suppress IFN, Promote Autophagy
2026-09-25
This study reports that hepatitis B surface antigen (HBsAg) alters TBK1 signaling in a way that weakens type I interferon production while promoting autophagosome accumulation. Its mechanistic findings connect TBK1 dimerization, disrupted TBK1–IRF3 association, p62 phosphorylation, and impaired autophagosome–lysosome fusion, offering a framework for investigating HBV persistence.

HBsAg Hijacks TBK1 to Suppress IFN and Alter Autophagy
2026-09-25
This study identifies a mechanism by which hepatitis B surface antigen (HBsAg) redirects TBK1 activity away from IRF3-dependent type I interferon signaling and toward early autophagy, while also impairing autophagosome–lysosome fusion. Evidence from experimental systems, HBsAg-transgenic mice, and chronic HBV liver tissues links this pathway to immune evasion and incomplete autophagy, although the findings do not establish a treatment strategy.

Phenothiazines Activate Macrophage Antibacterial Defenses
2026-09-24
A 2025 study reports that phenothiazines strengthen macrophage antibacterial activity alongside increased lysosomal activity, reactive oxygen species (ROS), and autophagy. Inhibiting autophagy or scavenging ROS weakened this effect, while perphenazine reduced lesions and inflammation in a mouse model of Salmonella Typhimurium infection, supporting further investigation of host-directed therapy.

Membrane Repair and Cytokine Control in Liver Infection
2026-09-24
A study of TMEM16F in Kupffer cells reframes liver infection around membrane integrity, cell survival, inflammation, and metabolism. This article explores how Ac-YVAD-CMK can help translational researchers test a distinct, caspase-1-dependent cytokine-processing hypothesis—without confusing it with the membrane-repair mechanism established by the study.

qPCR Quantification of Moloney Murine Leukemia Virus
2026-09-22
Choi, Murphy, and Nitta developed a real-time PCR assay that targets a packaging signal–gag region to quantify exogenous Moloney murine leukemia virus while reducing interference from endogenous retroviral sequences. The method detected viral sequences in infected mouse cells across a 16–72-hour post-infection window and provides a faster, scalable molecular complement to focal immunofluorescence assays.

Thioredoxin Control of CHK1 Inhibitor Sensitivity
2026-09-22
The reference study identifies the thioredoxin system as a determinant of CHK1 inhibitor response in non-small cell lung cancer. Its central advance is linking Trx1-dependent redox recycling of RRM1 to ribonucleotide reductase activity, deoxynucleotide availability, replication stress, and the therapeutic synergy between CHK1 and thioredoxin reductase inhibition.
