Summary
Researchers reviewed innovative nanotechnology platforms that deliver therapeutic gases like hydrogen to enhance cancer immunotherapy. These gas-generating nanoparticles can produce hydrogen, hydrogen sulfide, nitric oxide, and carbon monoxide directly at tumor sites. The gases work by boosting immune system responses against cancer cells through unique biological signaling mechanisms. The study examined how these nanoplatforms overcome traditional gas delivery challenges and improve treatment precision. While promising for future cancer therapy, researchers emphasize the need for more safety studies and clinical trials to establish effectiveness in human patients.
Abstract
Gas therapy, an emerging and promising tumor treatment strategy, has garnered increasing research interest. Recent attention has focused on gas signaling molecules due to their unique biological effects and potent immunomodulatory activities. With rapid advances in nanotechnology, diverse gas-generating nanoplatforms have been developed to augment cancer immunotherapy. This review first elucidates the mechanisms by which bioactive gas molecules amplify anti-tumor immunity and outlines design strategies for constructing gas-generating nanoplatforms. Thereafter, we summarize the applications of these nanoplatforms in gas-enhanced tumor immunotherapy, highlighting key bioactive gas signal molecules, including hydrogen sulfide (H2S), nitric oxide (NO), carbon monoxide (CO), and hydrogen (H2). Finally, the biosafety profiles of these systems and the prospects for future opportunities and challenges are discussed.
