e14076 Background: We report a biomimetic delivery platform based on human cytotoxic T-lymphocyte membranes. In this platform, T-lymphocyte membranes were camouflaged to the surface of poly-lactic-co-glycolic acid nanoparticles, with local low-dose irradiation (LDI) as a chemoattractant. These carriers were further anchored with the recombinant protein anti-EGFR-iRGD, improving tumor accumulation, facilitating tumor uptake. Methods: The T-lymphocyte membrane coating was verified by dynamic light scattering, transmission electron microscopy and confocal laser scanning microscopy. The particle phagocytosis study was performed using a human phagocytic cell line. In vivo NIR fluorescence imaging was performed to monitor the route of nanoparticles. EGFR expression of tumor cells was tested before and after LDI. Results: This new platform reduced phagocytosis of macrophages by 23.99% (p = 0.002). iRGD-EGFR anchored T-lymphocyte membrane-encapsulated nanoparticles accumulated in tumor site more than unfunctionalized groups, while LDI significantly enhanced the targeting ability. LDI could up-regulate EGFR expression on tumor cells, which was important in the process of localization of iRGD-EGFR anchored T-lymphocyte membrane-encapsulated nanoparticles in tumors. Conclusions: This new platform included both the long circulation time and tumor sites accumulation ability while LDI could significantly enhance the tumor accumulation ability.
