The 31 pages that link to Immune system, each with the reason it gives.

• Germ theory of diseaseRelated: Host defenses help determine whether microbial exposure leads to disease.

• Sleep deprivationRelated: Insufficient sleep can alter immune responses and increase vulnerability to illness.

• CortisolNarrower topic: Cortisol modulates immune activity and can suppress inflammation.

• Lymphatic systemNarrower topic: The lymphatic system provides key routes and meeting places for immune defense.

• MalnutritionRelated: Nutrient deficiencies can weaken immune defenses and increase infection risk.

• HematopoiesisRelated: Hematopoiesis supplies the immune system with its circulating and tissue-resident cells.

• Infectious diseaseRelated: Its response can control pathogens while also contributing to symptoms.

• Stress responseRelated: Stress mediators can alter immune activity, with effects depending on timing and duration.

• Nervous systemRelated: Immune activity exchanges signals with the nervous system and can alter neural function.

• Antiviral drugRelated: Drug effects work alongside immune defenses, which often help clear viral infection.

• Chemical defenseCompared with: Immune defenses act against internal threats, unlike ecological chemicals that deter external attackers.

• GlycosylationNarrower topic: Glycosylation can alter immune recognition and the activity of immune proteins.

• StressRelated: Prolonged stress can alter immune regulation and inflammatory activity.

• HostRelated: Host immune defenses can limit parasite survival or cause collateral damage.

• Bacterial infectionNarrower topic: Host immune defenses influence whether bacteria are cleared, contained, or cause illness.

• Programmed cell deathRelated: Immune responses use programmed death to remove infected cells and terminate excess lymphocytes.

• Regeneration (biology)Related: Immune signals can either support tissue rebuilding or promote scarring.

• Denisovan admixtureRelated: Archaic DNA may have affected immune-related traits as humans encountered new environments.

• Edward JennerNarrower topic: Vaccination works by engaging immune defenses before exposure to smallpox.

• OrganismRelated: Immune defenses help preserve the organism’s integrity against pathogens and abnormal cells.

• Complex systemBroader topic: Distributed recognition and response produce coordinated defense.

• HealthRelated: Immune function shapes vulnerability to infection and other disease.

• Zinc deficiencyRelated: Zinc shortage can impair immune-cell development and responses to pathogens.

• Myalgic encephalomyelitis/chronic fatigue syndromeRelated: Immune abnormalities are under investigation, but findings have not yielded a single confirmed cause.

• Biological factorsBroader topic: Immune activity can determine vulnerability and responses to disease.

• Human digestive systemRelated: Gut-associated immune defenses monitor a large interface with food and microbes.

• Niels Kaj JerneNarrower topic: Jerne’s theories concern how this complex system generates and regulates specific responses.

• Animal diseasesRelated: Immune responses can control infection, cause symptoms, or contribute to disease.

• Body & organ systemsRelated: Its defenses protect organs while distinguishing threats from the body's own tissues.

• Human biologyBroader topic: Its defenses distinguish threats from the body's own tissues.

• Human bodyBroader topic: Its defenses distinguish and respond to harmful agents within the body.
