Modification of immune cell-derived exosomes for enhanced cancer immunotherapy: current advances and therapeutic applications

초록

Cancer immunotherapy has revolutionized the approach to cancer treatment of malignant tumors by harnessing the body's immune system to selectively target cancer cells. Despite remarkable advances, there are still challenges in achieving successful clinical responses. Recent evidence suggests that immune cell-derived exosomes modulate the immune system to generate effective antitumor immune responses, making them a cutting-edge therapeutic strategy. However, natural exosomes are limited in clinical application due to their low drug delivery efficiency and insufficient antitumor capacity. Technological advancements have allowed exosome modifications to magnify their intrinsic functions, load different therapeutic cargoes, and preferentially target tumor sites. These engineered exosomes exert potent antitumor effects and have great potential for cancer immunotherapy. In this review, we describe ingenious modification strategies to attain the desired performance. Moreover, we systematically summarize the tumor-controlling properties of engineered immune cell-derived exosomes in innate and adaptive immunity. Collectively, this review provides a comprehensive and intuitive guide for harnessing the potential of modified immune cell-derived exosome-based approaches, offering valuable strategies to enhance and optimize cancer immunotherapy. The study investigates the use of tiny particles released from the immune system, known as immune cell-derived exosomes (IEXs), for cancer treatment. This research aspires to bridge the existing knowledge gap about engineering these IEXs to boost their inherent anti-cancer properties. The team of researchers, headed by PhD student, Inseong Jung and Sanghee Shin, and Professors Kyungmoo Yea and Moon-Chang Baek, investigated using gene alteration and physical and chemical changes to enhance the therapeutic potential of IEXs. The study included testing these altered IEXs on different immune and cancer cells, with the results indicating hopeful outcomes for cancer treatment. The researchers conclude that while these IEXs have substantial potential, further refinement and optimization are required to overcome limitations and enhance their clinical use. They also underline the potential of this method for future cancer-fighting strategies.This summary was initially drafted using artificial intelligence, then revised and fact-checked by the author.
