Highlighting the Potential Role of Exosomes as the Targeted Nanotherapeutic Carrier in Metastatic Breast Cancer

Breast cancer, being the second most common type of cancer, is a leading cause of death in the female population. Of all the available treatments existing for breast cancer, exosomes appear as an important medium for the site targeted delivery of the drugs. Exosomes, unlike all the other extracellular vesicles, play a vital role in the transport of numerous biomolecules throughout the body and can easily be detected because of the presence of specific biomarkers. Apart from playing a wide variety of roles in the progression of many diseases, they are also responsible for tumor progression and metastasis in breast cancer. Exosomes and related engineering strategies are being discussed as nano-carrier for the delivery of different drugs in the case of breast cancer. Overall, we have discussed in this review the role of exosomes in breast cancer and the engineering strategies being devised for making them an efficient drug delivery system.

Automated summary

Breast cancer, the second most common type of cancer, is a major cause of death among women. Exosomes, a type of extracellular vesicle, play a crucial role in the transportation of biomolecules throughout the body and can be easily detected due to specific biomarkers. They not only contribute to the progression of various diseases, but also play a role in tumor progression and metastasis in breast cancer. Exosomes and related engineering strategies are being explored as nano-carriers for drug delivery in breast cancer. This review discusses the role of exosomes in breast cancer and the development of engineering strategies to enhance their efficiency as drug delivery systems.
