An endoplasmic reticulum-enriched nanogel couples ferroptotic tumor damage with macrophage reprogramming for triple-negative breast cancer immunotherapy
Triple-negative breast cancer (TNBC) is characterized by severely immunosuppressive tumor microenvironment (TME), which leads to tumor ferroptosis resistance and dominant protumor M2 macrophages, restraining innate-to-adaptive antitumor immune cascade. Herein, an endoplasmic reticulum (ER)-enriched pH/redox-sensitive S...
