TMEM16F Lipid Scrambling and Ferroptosis
2026-08-31
Yang et al. identify TMEM16F-mediated plasma-membrane lipid scrambling as a late-stage suppressor of ferroptosis. The study shows that blocking this membrane-adaptation pathway increases lytic cell death, danger-signal release, and responsiveness to PD-1 blockade, providing a mechanistic framework for combining ferroptosis induction with tumor immunotherapy.

Ceramides Drive RGNNV Replication via Autophagy
2026-08-29
A 2026 Journal of Virology study uses global lipidomics and targeted perturbation experiments to show that red-spotted grouper nervous necrosis virus reorganizes ceramide metabolism and uses ceramide-dependent autophagy to support replication. The work connects viral capsid protein activity, sphingolipid pathways, and autophagy, while identifying ceramide flux as a possible intervention point in aquaculture virology.

Trichostatin A: Epigenetics Meets Ferroptosis
2026-08-28
Trichostatin A (TSA) is more than a histone deacetylase inhibitor: it is a reversible perturbation tool for testing how chromatin state, cell-cycle control, mitochondrial metabolism, and ferroptosis intersect. This article translates evidence on mitochondrial calcium signaling and GPX4 acetylation into a practical framework for oncology researchers while clearly separating established biology from forward-looking hypotheses.

L. plantarum DS0037 ELNs: Senolytic and Senomorphic Effects
2026-08-26
This 2024 study identifies exosome-like nanovesicles from Lactobacillus plantarum DS0037 as a microbial-derived candidate with both senolytic and senomorphic activity. The vesicles preferentially reduced senescent-cell viability, moderated inflammatory and matrix-remodeling markers, and produced early improvements in skin-elasticity-related measures, while the findings remain primarily preclinical and model-dependent.
