MRI示踪的纳米酶用于级联反应增强的免疫治疗
MRI-traceable Nanoenzyme for Cascade Catalysis-enhanced Immunotherapy
摘要
Abstract
The immunosuppressive tumor microenvironment(ITME)poses a significant challenge to anti-tumor immunotherapy.Our research develops a novel nanoenzyme based on Mn2+and endogenous hemin.The nanozyme possesses superior multi-enzymatic activities,which could significantly reverse the ITME and trigger a vigorous anti-tumor immune response,thereby inhibiting both tumor growth and metastasis when used in conjunction with immune checkpoint inhibitor(ICI),αPD-L1.Moreover,it functions as a magnetic resonance imaging(MRI)contrast agent for the visualization of tumors and the trace of nanoenzyme.关键词
