Nanoplastics–Cadmium Apoptosis via IP3R/Ca2+/STAT3
2026-08-26
A 2026 Toxicology study shows that combined polystyrene nanoplastic and cadmium exposure promotes intestinal apoptosis in C. elegans and Caco-2 cells through an IP3R/Ca2+/STAT3 signaling axis. Its inhibitor and calcium-chelation experiments position intracellular Ca2+ as a mechanistic mediator and provide a framework for interpreting co-contaminant toxicity in cell signaling studies.

Serine/Glycine Restriction, PD-L1 Lactylation, and CRC
2026-08-25
Tong et al. show that a serine/glycine-free diet can suppress colorectal cancer growth and strengthen cytotoxic T-cell activity while simultaneously promoting immune evasion through PD-L1 lactylation. The study combines preclinical mechanistic work with a single-arm phase I feasibility study, supporting dietary metabolic intervention as a potential adjunct to checkpoint blockade rather than as a stand-alone replacement for immunotherapy.

How p53 Loss Reprograms Macrophages via IL-34
2026-08-24
The 2024 Immunity study identifies an immune-escape circuit in which p53-inactivated liver cancer stem cells secrete IL-34, reprogram CD36-dependent foam-like macrophages, and suppress CD8+ T-cell activity. Its therapeutic experiments show that interrupting IL-34 signaling can sensitize these tumors to PD-1 blockade, while also defining important limits for translating the findings beyond the tested models.
