Significance of Natural killer cell
Natural killer cells are a crucial component of the immune system, as described in the provided text. They are part of the natural or innate immunity, directly eliminating target cells. Studies show an increase in these cells after interventions, and they are essential for immune surveillance against tumors and viruses. Furthermore, natural killer cells are involved in responses to the Hepatitis B Virus and play a role in inhibiting the proliferation of infected cells. They are also affected by stress and are stimulated by interleukin-15.

Hindu concept of 'Natural killer cell'
In Hinduism, Natural Killer cells represent a vital component of the body's innate defense. They combat the Hepatitis B virus and eliminate infected cells. Studies show that interventions can increase their numbers, along with T-helper cells, signifying a boost in immune function.

(1) It is part of the innate immunity, protecting the body against infections.[1] (2) Ashwagandha helps to reduce inflammation by increasing the availability of these in the body.[2] (3) Cells whose activity can be influenced by yoga, indicating a potential immunomodulatory effect.[3] (4) At 12 and 24 weeks of the practice, SKY dramatically enhanced natural killer (NK) cells in comparison to baseline among cancer patients.[4] (5) Vitamin C plays a crucial role in enhancing the body’s defenses against tumor cells by boosting the number of them.[5]

(1) These are cells that are part of the immune response to the Hepatitis B Virus, which helps in fighting the virus, as described in the text.[6] (2) Natural killer cells are part of the natural or innate immunity, recognizing antibody – coated target cells and directly causing the killing of the target, as the provided text states.[7] (3) The studies have shown the increase in natural killer cell and also increase in the percentage of T-helper cells after 4 weeks of intervention on healthy volunteers.[8]
The concept of Natural killer cell in scientific sources
Natural killer cells are vital immune cells that combat tumors and viruses. They are the body's primary defense against metastasis and are involved in inhibiting infected cells. Research also explores their role in kidney graft rejection, HIV-1 clearance, and how stress and coping styles impact their activity.

(1) Natural killer cell activity, spleen index and the CD 4 + /CD 8 + ratio in spleen cells were assayed, suggesting the importance of natural killer cell.[9] (2) These are immune cells that are stimulated and activated by direct-fed microbials, leading to an immune response.[10] (3) Ashwagandha modulates the immune response by augmenting the CD4 and CD8 counts and this activity.[11] (4) Melatonin acts as a stimulant for these cells, and experiments with melatonin and Echinacea with leukemic mice showed elevation in their count.[12] (5) These are regulated by macromolecular polysaccharides found in Tinospora cordifolia, which act on the receptor.[13]

(1) Chitosan has been shown to stimulate the immune system by boosting the concentration and activation of macrophages and these cells.[14] (2) Although estradiol treatment has immune enhancing effects on humoral immunity, both cell-mediated immunity and this activity are depressed following estradiol treatment in rats and mice.[15] (3) Immune cells and alterations in collagen density are signs of periradicular herpesvirus infection.[16] (4) The non-specific response of these cells destroy virus-infected cells, and virus‐specific T‐cell responses also play a major role in defense against viruses.[17]

(1) Active coping style is associated with these cytotoxicity in asymptomatic HIV-1 seropositive homosexual men, according to the text.[18] (2) These are immune cells stimulated by interleukin-15, which are studied for their ability to clear HIV-1-infected cells following latency reversal in experiments outside of a living organism.[19]
