主 题:CD47 colorectal cancer
摘 要:Cell membrane-camouflaged nanoparticles possess inherent advantages derived from their membrane structure and surface antigens,including prolonged circulation in the bloodstream,specific cell recognition and targeting capabilities,and potential for ***,we introduce a cell membrane biomimetic nanodrug platform termed MPB-3BP@CM *** microporous Prussian blue nanoparticles(MPB NPs)serving as both a photothermal sensitizer and carrier for 3-bromopyruvate(3BP),these nanoparticles are cloaked in a genetically programmable cell membrane displaying variants of signal regulatory proteinα(SIRPα)with enhanced affinity to *** a result,MPB-3BP@CM NPs inherit the characteristics of the original cell membrane,exhibiting an extended circulation time in the bloodstream and effectively targeting CD47 on the cytomembrane of colorectal cancer(CRC)***,blocking CD47 with MPB-3BP@CM NPs enhances the phagocytosis of CRC cells by ***,3BP,an inhibitor of hexokinase II(HK2),suppresses glycolysis,leading to a reduction in adenosine triphosphate(ATP)levels and lactate ***,it promotes the polarization of tumor-associated macrophages(TAMs)towards an anti-tumor M1 ***,integration with MPB NPs-mediated photothermal therapy(PTT)enhances the therapeutic efficacy against *** advantages make MPB-3BP@CM NPs an attractive platform for the future development of innovative therapeutic approaches for ***,it introduces a universal approach for engineering disease-tailored cell membranes for tumor therapy.
