; Immune Phenomena
: '''Allergies''' → When the system treats a harmless antigen (like pollen or peanuts) as a deadly threat, causing a massive, dangerous "Over-reaction."
: '''HIV/AIDS''' → A virus that specifically attacks the '''Helper T Cells''', effectively "cutting the phone lines" of the immune system so it can't coordinate a defense.
: '''Cytokine Storm''' → When the immune system releases too many signals, causing it to attack the body's own organs (a major cause of death in severe COVID-19).
: '''The Microbiome''' → The trillions of bacteria in your gut that actually help "train" your immune system and keep it healthy.
