摘要
Disclosed are an inflammation-targeted neutrophil granulocyte drug delivery system and use thereof, wherein the drug delivery system includes neutrophil granulocytes and a therapeutic substance or a detectable substance loaded into the neutrophil granulocytes or onto the surface of the neutrophil granulocytes in a direct or indirect way. By using the neutrophil granulocytes as a carrier of a drug, the drug is actively targeted to an inflammatory site, thereby increasing the drug concentration at the inflammatory site. Under the stimulation of cytokines, the neutrophil granulocytes arriving at the inflammatory site are abnormally activated, disintegrate rapidly, and die in the way of “Neutrophil extracellular traps (NETs)”. This helps to rapidly release the loaded drug to the targeted site, so as to improve the therapeutic effect and reduce the toxic and side effects.
