Natural killer nk cells and cd8 cytotoxic t cells are two types of immune cells that can kill target cells through similar cytotoxic mechanisms. Aaron lebeau of the university of minnesota and his team are developing an interesting and provocative new type of immunotherapy using a specific type of immune cell called natural killer cells or nk cells for short. The efficacy of nk cell mediated immunotherapy can be enhanced by immune. With the remarkable success of chimeric antigen receptor car engineered t car t cells for treating haematological malignancies there is a rapid growing interest in developing car engineered nk car nk cells for cancer therapy.

The immunotherapy that remains on the front burner is car t. Natural killer nk cells are crucial components of the innate immune system and play critical roles in host immunity against viral infections and cancer. Cancer immunotherapy has been firmly established as a new milestone for cancer therapy with the development of multiple immune cells as therapeutic tools. Nk cells activity is controlled by the interaction of a wide range of receptors expressed on their surfaces with cell surface ligands.

Meaning the cancer cells lack estrogen or progesterone receptors and make very little of the. Natural killer cells plus immunotherapy for triple negative breast cancer. Nk cells can be targeted to kill with exquisite antigen specificity by antibody. Natural killer nk cells have evolved to complement t and b cells in host defense against pathogens and cancer.

With the remarkable success of chimeric antigen receptor car engineered t car t cells for treating haematological malignancies there is a rapid growing interest in developing car engineered nk car nk cells for cancer therapy. In this process t cells a type of white blood cell that are part of the body s immune system are extracted from a person s. They recognize infected cells and tumors using a sophisticated array of activating costimulatory and inhibitory receptors that are expressed on nk cell subsets to create extensive functional diversity.

Natural killer nk cells are innate immune cells endowed with potent cytolytic activity against tumors and meanwhile act as regulatory cells for the immune system. These cells are like beat cops on patrol traveling around the body to look for and kill cells infected with a virus bacteria and cancer cells.
