Summary
Researchers reviewed cutting-edge nanotechnology approaches for treating rheumatoid arthritis that combine multiple therapeutic methods. The technology uses tiny particles that release hydrogen gas to reduce inflammation, while also incorporating light therapy to heat and destroy diseased tissue, light-activated treatments that create healing molecules, and sound waves for imaging and treatment. This multimodal approach targets inflamed joints more precisely than traditional medications while potentially reducing side effects. The hydrogen component specifically helps control the inflammatory environment by neutralizing harmful molecules. This comprehensive review suggests these combined nanotechnologies could represent a major advancement in arthritis treatment.
Abstract
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease. Current treatments mainly involve drugs and surgery, but face limitations like adverse effects, invasive complications, and poor outcomes. Emerging nanomaterial-mediated modalities, particularly photothermal therapy (PTT), photodynamic therapy (PDT), photoacoustic (PA) imaging, sonodynamic therapy (SDT), and gas therapy, have demonstrated the potential to address these limitations. PTT leverages near-infrared (NIR)-responsive nanomaterials to induce localised hyperthermia, triggering apoptosis in pathogenic synovial tissues. PDT relies on photoactivated nanophotosensitizers to precisely eliminate hyperplastic synovium through spatiotemporally controlled reactive oxygen species (ROS) production. PA imaging uses NIR light to excite nanoparticles, generating ultrasound signals that are reconstructed into images, enabling real-time monitoring and assessment of RA joints. SDT employs ultrasound-activated nanosensitizers to produce cytotoxic ROS for the targeted ablation of inflammatory cells. Complementing these approaches, gas therapy, mediated by hydrogen-releasing nanomaterials, exerts immunomodulatory effects by scavenging ROS and regulating the inflammatory microenvironment. This review examines cutting-edge nanotherapeutic strategies that integrate photonic, acoustic, and gaseous modalities for RA management. Through an analysis of innovative nanosystem designs and their therapeutic mechanisms, this review highlights the emerging paradigm of synergistic multimodality approaches, which improve efficacy while reducing systemic adverse effects. This review will provide novel perspectives for advancing next-generation multimodal precision therapies for autoimmune diseases.
