There has been a lot of research that suggests that the immune system can be severely affected by stress. Kiecolt-Glaser did an experiment to evaluate the effect of acute stressors on the immune system. She had a group of students who were about to have their medical exams. She took the blood sample one month before the exams and another during the exam period. She measured the NK cell activity to see how the immune system was effected and found that the NK cell activity had dropped significantly

In a more specific manner, the receptors found on the surface of the natural killer cells present in the innate immune system, known as natural cytotoxicity receptors (NCR), are stimulated by co stimulatory molecules, created from the binding of a MHC protein and an antigen, and also the pattern recognition receptors, such as toll-like

of the 75 participants one month before their final exams and then again on the first day of exams. The blood samples were then analysed for leucocyte activity of the natural killer cell. Questionnaires were also given to establish the students’ psychiatric mind set and their life events. They found that the natural killer cell activity decreased in the second blood sample, compared with the first. Furthermore, immune response was particularly low for those who scored highly in the loneliness, psychiatric

cytotoxicity of natural killer cells is a topic that is still being investigated today, specifically the question at hand is “How does a cytotoxic T cell (or NK cell) avoid being killed by the perforin and granzymes that it secretes to kill a target cell?” In the field, what is known about the topic includes the function of these natural killer cells, the mechanism of action of the perforin released by these cells, and health issues associated with nonfunctional perforin. Natural killer cells are a type

very beneficial. Video cameras have captured many crimes and resulted in the conviction of very dangerous criminals. “Law enforcement agencies say surveillance cameras have become a valuable crime-fighting weapon, like capturing the infamous Craigslist killer, who was identified on hotel surveillance”(Surveillance, 2012).
