To Protect You from Cancer and Viral Infection

White blood cells consist of neutrophils, lymphocytes, monocytes, basophils, and eosinophils, and eliminate foreign pathogens (i.e., bacteria and viruses) and transformed cells (i.e., cancer cells) in your body.


Natural killer cells (also known as NK cells) are a population of lymphocytes that promptly attack and eliminate cancer cells and virus-infected cells.


In NK cell therapy, NK cells are expanded and activated by cell culture, and administered to you for the prevention or treatment of cancer as well as viral infection.


Cancer Cells Emerge Every Day

It has been reported that more than 5,000 cancer cells emerge every day in healthy individuals. However, the newly emerged cancer cells are recognized and killed by NK cells, which patrol through the body, so that they do not develop into cancer masses.


Do You Know Your NK Activity?

Your NK activity can be measured and scored at Tokyo Clinic. NK activity represents the ability of your lymphocytes to destroy cancer cells. Aging and stress can decrease the NK activity, making you more susceptible to cancer or viral infection. According to a cohort study, individuals with low NK activity have 70% increased risks of developing cancers compared to those with medium to high NK activity.



NK Cell Therapy to Boost Your Immunity and Reduce the Risk of Cancer and Viral Infection

Tokyo Clinic offers a sophisticated immune cell therapy, i.e., NK cell therapy, in which your own blood cells are cultured at a cell processing facility certified by the Ministry of Health, Labor and Welfare, Japan so that your NK cells are activated and increased in number by several hundred to several thousand-fold. The cultured NK cells are then administered to you by intravenous infusion. Use of your own cells makes it less likely to cause undesirable immune responses.



You may hardly imagine you could suffer from severe diseases or cancers when you are doing well. However, the reality is that one in two Japanese are diagnosed with cancer in their lifetimes.


Cancer treatment is not an easy task, and it is better to eliminate cancer cells before they develop into a cancer mass. Since NK cells recognize and kill cancer cells, NK cell therapy is expected to augment your anticancer immunity and decrease the risk of cancer development.


NK cell therapy is also expected to prevent influenza, coronavirus infection and common cold.
