Hypoxia-tropic delivery of nanozymes targeting transferrin receptor 1 for nasopharyngeal carcinoma radiotherapy sensitization.

Nat Commun

January 2025

Nasopharyngeal carcinoma (NPC), a malignancy highly prevalent in East and Southeast Asia, is primarily treated with radiotherapy (RT). However, hypoxia-induced radioresistance presents a significant challenge. Nanozymes, nanomaterials with catalase-like activity, have emerged as a promising strategy for radiosensitization by converting elevated hydrogen peroxide in the tumor microenvironment into oxygen.

Department of Pharmaceutics, College of Pharmacy, Chongqing Medical University, Chongqing 400016 China. Electronic address:

Loading drug-maleimide (MAL) conjugates into liposomes preloaded with glutathione (GSH) can prepare the liposome encapsulating GSH-conjugated prodrugs, which serve as a feasible way to construct liposomal formulation. However, the effects ofthelinker on the development of this liposomal system remained unclear. Herein, docetaxel (DTX)-MAL conjugates linked by various linkers were used for such studies.

Engineered allogeneic stem cells orchestrate T lymphocyte driven immunotherapy in immunosuppressive leptomeningeal brain metastasis.

J Natl Cancer Inst

January 2025

Center for Stem Cell and Translational Immunotherapy, Brigham and Women's Hospital, Harvard Medical School, Boston, 02115, Massachusetts, USA.

Background: Immune-checkpoint inhibitors have shown clinical benefit in non-small cell lung cancer (NSCLC) derived brain metastasis (BM), however, their efficacy in lung to leptomeningeal brain metastasis (LLBM) remains poor.

Methods: A paired matched RNA expression dataset of patients with NSCLCs and BMs was analyzed to idenfiy BM specific suppressive tumor microenvironment (TME) features. Next, we created immune-competent LLBM mouse models that mimic clinical LLBM.

Key principles of rheumatoid arthritis (RA) management include early patient evaluation by a rheumatologist and early initiation of pharmacologic therapy in patients at risk for chronic disease. Early diagnosis and appropriate management are essential to prevent joint damage. Patients with RA usually report pain and swelling in multiple joints and prolonged stiffness in the morning that improves with activity.
