Nano-engineered immune cells as guided missiles for cancer therapy

Immune cells can actively regulate tumors or inflammatory sites and have good biocompatibility and safety. Currently, they are one of the most promising candidates for drug delivery systems. Moreover, immune cells can significantly extend the circulation time of nanoparticles and have broad-spectrum tumor-targeting properties. This article first introduces the immune cell types most commonly used in recent years, analyzes their advantages and disadvantages, and elucidates their application in anti-tumor therapy. Next, the various ways of loading nanoparticles on immune cells that have been used in recent years are summarized and simply divided into two categories: backpacks and Trojan horses. Finally, the two mountains that stand in front of us when using immune cells as cell carriers, off-target problems and effective release strategies, are discussed.

Automated summary

Immune cells, with their good biocompatibility and safety, are promising candidates for drug delivery systems, especially in anti-tumor therapy. The methods of loading nanoparticles on immune cells can be divided into backpacks and Trojan horses. However, challenges such as off-target problems and effective release strategies still need to be addressed when using immune cells as cell carriers.
