Photodynamic therapy (PDT), utilizing a photosensitizer (PS) to induce tumor cell death, is an effective modality for cancer treatment. PS-peptide conjugates have recently demonstrated remarkable antitumor potential in preclinical trials. However, the limited cell membrane binding affinity and rapid systemic clearance have hindered their transition to clinical applications.

Tuberculosis (TB) is one of the leading causes of death in the world, despite being a preventable and curable disease. Irrespective of tremendous advancements in early detection and treatment, this disease still has high mortality rates. This is due to the development of antibiotic resistance, which significantly reduced the efficacy of antibiotics, rendering them useless against this bacterial infection.

Introduction: Ulcerative colitis (UC) is an inflammatory bowel disease characterized by inflammation and ulceration of the digestive tract.
Methods: Photodynamic therapy (PDT) with a novel photosensitizer LD was used to treat UC rat models to explore the therapeutic effect and mechanism of LD-PDT on UC. 16S ribosomal RNA was used to detect the composition of Gut microbiota.

The use of hypoxia-activated prodrugs is a promising strategy to address the limitations of photodynamic therapy (PDT) caused by a hypoxic tumor microenvironment. However, the controlled release of these hypoxia-activated prodrugs during PDT remains a challenge. In this study, we present a metal-organic framework (MOF) with a core-shell structure that can achieve a high PDT efficacy and on-demand release of hypoxia-activated prodrugs (AQ4N) for hypoxic tumor therapy.

Photoimmunotherapy, which combines phototherapy with immunotherapy, exhibits significantly improved therapeutic effects compared with mono-treatment regimens. However, its use is associated with drawbacks, such as insufficient reactive oxygen species (ROS) production and uneven photosensitizer distribution. To address these issues, we developed a controllable, targeted nanosystem that enhances oxidative stress through multiple pathways, achieving synergistic photothermal, photodynamic, and immunotherapy effects for tumor treatment.
