Macrophage‐Biomimetic Nanoplatform‐Based Therapy for Inflammation‐Associated Diseases.

Inflammation‐associated diseases are very common clinically with a high incidence; however, there is still a lack of effective treatments. Cell‐biomimetic nanoplatforms have led to many breakthroughs in the field of biomedicine, significantly improving the efficiency of drug delivery and its therapeutic implications especially for inflammation‐associated diseases. Macrophages are an important component of immune cells and play a critical role in the occurrence and progression of inflammation‐associated diseases while simultaneously maintaining homeostasis and modulating immune responses. Therefore, macrophage‐biomimetic nanoplatforms not only inherit the functions of macrophages including the inflammation tropism effect for targeted delivery of drugs and the neutralization effect of pro‐inflammatory cytokines and toxins via membrane surface receptors or proteins, but also maintain the functions of the inner nanoparticles. Macrophage‐biomimetic nanoplatforms are shown to have remarkable therapeutic efficacy and excellent application potential in inflammation‐associated diseases. In this review, inflammation‐associated diseases, the physiological functions of macrophages, and the classification and construction of macrophage‐biomimetic nanoplatforms are first introduced. Next, the latest applications of different macrophage‐biomimetic nanoplatforms for the treatment of inflammation‐associated diseases are summarized. Finally, challenges and opportunities for future biomedical applications are discussed. It is hoped that the review will provide new ideas for the further development of macrophage‐biomimetic nanoplatforms. [ABSTRACT FROM AUTHOR]
