Large granular lymphocytes known as Natural Killer Cells are rapid to react to a pathogenic threat. They are also in charge of making immunoregulatory cytokines. Additionally, they play a crucial role in the human innate immune system. The primary function of NK cells is to trigger an immune response against viral infections and cancers.
These cells have been utilised in numerous molecular and combinational therapies during the past few years, which has expanded the utilisation of such medicines.In order to explore and create better medicines for the treatment of infections and malignancies, research is being done to culture Natural Killer Cells outside of the body. Additionally, they can replace T cells as an efficient therapeutic weapon against cancer and viral disorders. One of the main factors propelling the expansion of the Natural Killer Cells therapeutics is the rise in the use of NK cells for the treatment of cancer, infections, and liver illnesses. Additionally, NK cells are essential for tumour immune surveillance, which promotes the use of NK treatments all over the world. The need for the most effective therapeutic strategy is growing daily since cancer is a severe disease and because current treatment options could lead to tumour recurrence. The use of immunotherapies to treat various cancers has received a lot of interest recently. Among immunotherapies, CAR-T cell therapies have been investigated and employed, but they have a number of drawbacks that prompted the creation of Natural Killer Cells therapies. It is necessary to increase public awareness because a medicine based on the therapeutic use of natural killer (NK) cells has not yet received approval. Older persons are typically affected by chronic conditions including heart disease, arthritis, diabetes, stroke, or cancer that can be managed but not cured. A major challenge in global healthcare is chronic diseases. The burden of chronic diseases is rising globally as a result of lifestyle changes such reduced physical activity, poor food, and tobacco use. Natural Killer Cells therapy, which has the potential to elicit a potent immune response and also has anti-tumor capabilities, can be used to provide patients with the best curative treatment option. An increasing number of patients with chronic diseases have inspired scientists and researchers to work on a new innovative therapeutic approach. Therapeutics utilising natural killer (NK) cells target numerous pathogenic antigens with effective cytotoxicity and lower the danger of cytokine storms. They can be made from a multitude of sources without relying on immune cells that are unique to a patient. Currently, a number of methods have been established to increase the efficacy of NK cells therapies, such as ex vivo pre-conditioning with cytokines or small molecular medicines and creating a chimeric antigen receptor (CAR) NK.
