Selective Autophagy Tunes IRF3 and IFN Responses
2026-09-15
Wu et al. show that CALCOCO2/NDP52-mediated selective autophagy degrades IRF3 in a virus-load-dependent manner, while PSMD14 preserves basal IRF3 by removing K27-linked ubiquitin chains. The study defines a regulatory circuit that balances antiviral type I interferon production with immune suppression and clarifies how ubiquitin editing intersects with autophagic clearance.

Luminescent ATP Cell Viability Assay Kit I
2026-09-15
The Luminescent ATP Cell Viability Assay Kit I uses ATP-dependent firefly luciferase luminescence detection for rapid, sensitive cell viability measurement. Its reported 10 to 30,000-cell linear range and detection as early as 10 minutes support cytotoxicity, proliferation, and ferroptosis studies, while the ATP endpoint does not by itself identify a specific death mechanism.

Concanavalin A Targets Conserved Coronavirus N-Glycans
2026-09-11
Guo and colleagues identify conserved high-mannose N-linked glycans near the coronavirus spike S2′ cleavage site as a broad antiviral vulnerability. Using fusion, pseudovirus, authentic-virus, biochemical, and mouse models, the study shows that concanavalin A inhibits spike activation and entry rather than targeting rapidly changing antibody epitopes.

Selective Autophagy Tunes IRF3 Stability
2026-09-10
The reference study identifies CALCOCO2/NDP52-mediated selective autophagy as a virus-load-dependent mechanism that removes IRF3 and limits excessive type I interferon signaling. It further shows that PSMD14 preserves IRF3 by editing K27-linked ubiquitin chains at Lys313, defining a regulatory axis that connects ubiquitin remodeling, autophagic turnover, and antiviral immune suppression.

Thermal Shift Assay for Bacterial Sensor Ligands
2026-09-08
This 2025 review explains how thermal shift assays identify ligands for bacterial receptors, solute-binding proteins, and transcriptional regulators when their native signals are unknown. Its central practical message is that protein engineering, pH optimization, careful interpretation of thermal shifts, and orthogonal binding measurements such as ITC are essential for converting screening hits into credible biological hypotheses.
