Recent progress in therapeutic strategies and biomimetic nanomedicines based on neutrophils for inflammation treatment.

Inflammation is a defensive response that helps repair and restore damaged tissue by activating immune and nonimmune cells against pathogens. However, inflammation may cause chronic disease if it persists for a long time. Neutrophils recruit immediately to the lesion site and regulate the inflammatory process when inflammation occurs. Therefore, neutrophil-mediated therapy has been considered as a promising strategy for inflammatory diseases and has been extensively studied. In this review, we summarize the recent research progress of neutrophil-based personalized treatment strategies for inflammation. We also review the research progress of various neutrophil-mediated drug-delivery systems in combination with the inflammatory microenvironment.
