Cancer Immunotherapy and Nanomedicine

A review paper: "The immune system has the ability to recognize and kill pre-cancer and cancer cells. However, with the immune system's surveillance, the survival tumor cells learn how to escape the immune system after immunoselection. Cancer immunotherapy develops strategies to overcome these problems. Nanomedicine applications in cancer immunotherapy include the nanodiagnostics and nanobiopharmaceuticals. In cancer nanodiagnostics, it looks for specific 'molecular signatures' in cancer cells or their microenvironment by using genomics and proteomics. Nanobiopharmaceuticals is the field that studies nanotechnology-based therapeutic agents and drug carriers. DNA, RNA, peptides, proteins and small molecules can all be used as cancer therapies when formulated in nanocarriers. Currently, cancer vaccines are applied in treatments with existing cancer or to prevent the development of cancer in certain high risk individuals. Most of the non-specific immune activation agents include adjuvants which enhance immunogenicity and accelerate and prolong the response of cancer vaccines. The carriers of vaccines, such as viruses and nanoparticles, have also been in clinical studies for many years."
