The activation and inhibition of Natural Killer cells is dependent on the balance between stimulation of activating and inhibitory receptors. If the stimulation of activating receptors is more prominent than NK cells will be activated‚ likewise if inhibitory receptors stimulation is dominant than NK cells activity will be suppressed. For the immune system to work the first and foremost requirement is that it should be able to determine whether a cell is infected or not and then it can defend the

Outline and Evaluate Research into the Relationship between the Immune System and Stress Related Illness There is evidence to suggest acute stressors can cause suppression of the immune system and decrease immune cell functioning. The study by Kiecolt-Glaser et al. (1984) investigated whether the stress of taking exams caused a change in the amount of white blood cells in the blood. Kiecolt-Glaser studied 49 male and 26 female first year medical students at the Ohio State University College
