6-OHDA Models Need More Than Lesion Confirmation
2026-09-23
6-OHDA hydrochloride can support controlled studies of catecholaminergic injury, but a measurable lesion is not, by itself, a translational result. This article outlines how to connect mechanism, experimental controls, and decision-relevant endpoints—and what nanoparticle research can teach about interpreting function without implying an unproven connection to 6-OHDA.

Lipidated Nanophotosensitizer Blocks Tumor Metastasis
2026-09-22
The reference study developed a palmitic acid-displayed nanophotosensitizer that traces tumor extracellular vesicles (TEVs) and generates reactive oxygen species inside both tumor cells and TEVs. In female mouse models, near-infrared treatment suppressed primary tumors while disabling TEV-mediated communication, offering a preclinical strategy for addressing tumor growth and metastasis together.
