Because healthy proliferating cells do not rely on sustained FOXO4p53 sequestration for survival, they are less affected in experimental models
This can be done using stressful situations or by injecting lipopolysaccharide, an endotoxin from bacteria.[ref] Animals bred not to produce IL-6 are resistant to despair behavior usually induced by stress.[ref] Genetic studies in humans also link higher levels of IL-6, stressful life events, and an increased risk of depression.[ref] Interleukin-6 is one of the major cytokines released by immune cells in response to a pathogen or toxin
