Overcoming Photodynamic Therapy Resistance: GSH‐Responsive AIE Photosensitizer‐Hydroxycamptothecin Nanoliposomes for Extrahepatic Cholangiocarcinoma

Advanced Healthcare Materials, EarlyView.
A GSH‐responsive AIE nanoplatform (TSH NPs) with RGD‐mediated tumor targeting co‐delivers a photosensitizer (TPA) and HCPT for extrahepatic cholangiocarcinoma. The system synergistically enhances PDT and chemotherapy by suppressing HIF‐1α/VEGF‐driven hypoxic adaptation, effectively overcoming PDT resistance.

β-Amyloid peptides induce mitochondrial dysfunction and oxidative stress in astrocytes and death of neurons through activation of NADPH oxidase [PDF]

, 2004
β-Amyloid (βA) peptide is strongly implicated in the neurodegeneration underlying Alzheimer's disease, but the mechanisms of neurotoxicity remain controversial. This study establishes a central role for oxidative stress by the activation of NADPH oxidase
