The STING (stimulator of interferon genes) pathway offers a route to convert immunogenic “cold” TNBC into “hot” tumors, improving sensitivity to immune checkpoint blockade. Clinical translation remains constrained by inadequate cytosolic delivery, rapid systemic degradation, and tumor microenvironment-driven metabolic inactivation. This review summarizes advances in STING-mediated nanoparticle delivery, including biomimetic and stimuli-responsive systems, and discusses mechanisms linking ferroptosis, cuproptosis, and mitochondrial DNA disruption to type I interferon amplification and dendritic cell maturation, highlighting synergy with ICB.",{"@graph":69,"@context":123},[70,84,106],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":35,"@type":76,"position":81},"https://docshare.wps.com/document/healthcare/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/stimulator-of-interferon-genes-sting-activating-nanomedicines-translating-innate-immune-modulation-into-effective-therapy-for-triple-negative-breast-cancer/444196/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/stimulator-of-interferon-genes-sting-activating-nanomedicines-translating-innate-immune-modulation-into-effective-therapy-for-triple-negative-breast-cancer/444196.png","ImageObject",300,407,{"name":92,"@type":93},"Nguyễn Văn Học","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-27","2026-09-29",true,{"@type":102,"interactionType":103,"userInteractionCount":105},"InteractionCounter",{"@type":104},"ViewAction",11,{"@type":107,"mainEntity":108},"FAQPage",[109,115,119],{"name":110,"@type":111,"acceptedAnswer":112},"What makes triple-negative breast cancer difficult to treat in conventional therapy?","Question",{"text":113,"@type":114},"TNBC has profound immunosuppressive complexity and lacks hormone receptors, removing eligibility for hormone-based conventional therapies and contributing to treatment resistance.","Answer",{"name":116,"@type":111,"acceptedAnswer":117},"How does the STING pathway aim to improve TNBC immunotherapy?",{"text":118,"@type":114},"STING signaling can convert immunologically “cold” TNBC tumors into “hot” tumors, increasing responsiveness to immune checkpoint blockade by enhancing innate immune activation.",{"name":120,"@type":111,"acceptedAnswer":121},"Which delivery and tumor microenvironment factors hinder clinical translation of STING activation?",{"text":122,"@type":114},"Insufficient cytosolic delivery, rapid systemic degradation, and tumor microenvironment-induced metabolic inactivation reduce effective STING engagement in patients.","https://schema.org",{"og:url":83,"og:type":125,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":127,"canonical":83},"index,follow",{"doc_id":129,"site_id":62},444196,1790952829,{"code":4,"msg":5,"data":132},{"doc_id":129,"user_id":133,"nickname":92,"user_avatar":134,"doc_module":4,"category_id":34,"category_name":35,"doc_title":65,"doc_description":67,"doc_content":135,"file_id":136,"file_url":137,"file_type":138,"file_size":139,"view_count":105,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":140,"language":141,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":142,"faqs":143,"seo_title":144,"seo_description":67,"update_tm":145,"read_time":146,"preview_page_count":4},1374402739827,"https://ap-avatar.wpscdn.com/avatar/14000c97e7351f1a627?x-image-process=image/resize,m_fixed,w_180,h_180&k=1787885694763230660","DOI: 10.1002/ctm2.70580  \nREVIEW  \nStimulator of interferon genes (STING)-activating nanomedicines: Translating innate immune modulation into effective therapy for triple-negative breast cancer  \nHarshita Singhai1  Taha Alqahtani2  Humood Al Shmrany3  Garima Gupta4, 5  Umesh Kumar Patil1  Amirhossein Sahebkar6  Prashant Kesharwani1  \n1 Department of Pharmaceutical Sciences, Dr. Harisingh Gour Vishwavidyalaya (A Central University), Sagar, Madhya Pradesh, India  \n2 Department of Pharmacology, College of Pharmacy, King Khalid University, Abha, Saudi Arabia  \n3 Department of Medical Laboratory, College of Applied Medical Sciences, Prince Sattam Bin Abdulaziz University, Al-Kharj, Saudi Arabia  \n4 Graphic Era Hill University, Dehradun, India  \n5 School of Allied Medical Sciences, Lovely Professional University, Phagwara, Punjab, India  \n6 Biotechnology Research Center, Pharmaceutical Technology Institute, Mashhad University of Medical Sciences, Mashhad, Iran  \nCorrespondence  \nAmirhossein Sahebkar, Biotechnology Research Center, Pharmaceutical Technology Institute, Mashhad University of Medical Sciences, Mashhad, Iran.
