Significance of Natural Killer cells
Natural Killer cells are a type of immune lymphocyte that play a crucial role in the body's innate immune response. They have the ability to directly kill virus-infected and cancerous cells, contributing significantly to anticancer immunity. NK cells are involved in various mechanisms such as antibody-dependent cell-mediated cytotoxicity (ADCC) and are characterized by the expression of the CD56 marker. Their activity can be influenced by stress and practices like pranayama, highlighting their importance in maintaining immune health.

The concept of Natural Killer cells in scientific sources
Natural Killer (NK) cells are a type of lymphocyte crucial in the immune response against tumors. Their activity is notably assessed in Head and Neck Cancer (HNC) patients, indicating their role in cancer immunotherapy.
From: The Malaysian Journal of Medical Sciences
(1) Natural killer cells are immune cells that initiate ADCP and ADCC of infected cells after the Fc portions of antibodies bind to their receptors.[1] (2) These cells are associated with the mechanism of antibody-dependent cell-mediated cytotoxicity, which eliminates infected cells through various pathways.[2] (3) A type of immune cell that plays a critical role in the innate protection against lethal infections, including Ebola virus infections.[3] (4) A type of lymphocyte that plays a crucial role in the body's innate immune response, particularly against tumor cells.[4] (5) Natural killer (NK) cells are a type of immune cell involved in preventing cancer metastasis, which may be inhibited by chronic stress.[5]
