Viral RIPK3 Degradation and Inflammation: Study Insights
2026-08-28
Liu and colleagues identified a cowpox virus protein family that recruits host SCF ubiquitin-ligase machinery to degrade RIPK3, thereby suppressing necroptosis while enhancing viral fitness and disease severity. The study combines screening, viral genetics, biochemical analysis, and mouse epistasis experiments to show that vIRD–RIPK3 interactions shape orthopoxvirus pathogenesis.

MCL-1’s Canonical Apoptotic Role in Breast Cancer
2026-08-27
This Cell Death & Differentiation study shows that established breast tumors depend on MCL-1 primarily for its canonical anti-apoptotic function, rather than for an independent non-apoptotic activity. By combining acute genetic deletion, selective pharmacological inhibition, and BAX/BAK loss-of-function experiments, the authors connect MCL-1 dependence to mitochondrial apoptosis and identify a related role in breast cancer stem-cell activity.

Dhx9 Helicase Directs TH17 Autoimmunity
2026-08-26
Su et al. identify the nuclear helicase Dhx9 as a chromatin-level regulator of TH17 lineage commitment, linking IL-6–STAT3 signaling to accessibility at the Rorc and Il17 loci. Genetic deletion and pharmacological inhibition reduced TH17 differentiation and autoimmune disease severity in mouse models, highlighting transcriptional-program control as a potential complement to cytokine blockade.

Intraperitoneal CAR-M Programming for Cancer Immunotherapy
2026-08-25
Gu et al. developed a macrophage-targeted mRNA-LNP platform for in situ evaluation of 36 CAR formats in peritoneal cancer. Their results identify a CD3ζ–TLR4 intracellular-domain design that sustains inflammatory macrophage activity, reshapes the tumor microenvironment, expands TCF1+PD-1+ progenitor-exhausted CD8+ T cells, and enhances PD-1/PD-L1 therapy.
