Nano-bio-encapsulation of phyto-vaccines: a breakthrough in targeted cancer immunotherapy

Nano bio-encapsulation of phyto-vaccines for cancer has marked a cutting-edge strategy that brings together nanotechnology with plant-derived vaccines to enhance cancer therapy. Phyto-vaccines, isolated from bioactive compounds found in plants called protein bodies, have been shown to potentially stimulate the immune system to recognise and destroy cancer cells. However, challenges such as poor stability, rapid degradation, and limited bioavailability in the body have hindered their clinical application. Nano bio-encapsulation offers a solution by packaging these phyto-vaccines into nanoscale carriers such as lectins have provided ways to overcome these limitations. They protect the protein bodies from degradation by proteolytic enzymes, enhance targeted delivery to cancer cells, and enable controlled release. This approach not only improves the bio-distribution and potency of the vaccines but also minimizes side effects, making it a highly promising, sustainable, and efficient method for cancer immunotherapy. As research progresses, this technology has the potential to revolutionize cancer treatment by providing safer and more precise therapeutic options. This review focuses on the concept of nano bio-encapsulation of phyto-vaccines for cancer treatment. It explores how nanotechnology can enhance the stability, bioavailability, and targeted delivery of plant-derived vaccines, addressing the limitations of traditional vaccines. The review delves into the potential of this innovative strategy to advance cancer immunotherapy, providing a comprehensive overview of current research and future directions.
