Nanocatalytic Phase Separation Augments Tumor‐specific cGAS‐STING Activation for Spinal Metastasized Breast Cancer Metalloimmunotherapy
The cGAS‐STING pathway is a pivotal therapeutic target for antitumor immunity, yet clinical translation of its small‐molecule agonists is hindered by poor tumor specificity, suboptimal pharmacokinetics, and systemic off‐target effects. Here, we report a nanocatalytic strategy based on a tumor microenvironment (TME)‐res...
