; Immunology Landmarks
: '''The 'Starfish' Experiment (1882)''' → Elie Metchnikoff watched a starfish cell "Eat" a thorn, discovering Phagocytosis and proving that cells—not just blood—protect the body.
: '''Toll-Like Receptors (TLRs)''' → The 1990s discovery of the "Eyes" of the innate system, which won the Nobel Prize.
: '''The Hygiene Hypothesis''' → The theory that because our modern world is "Too Clean," our innate immune system doesn't get enough "Practice" and starts attacking harmless things like pollen (Allergies).
: '''Sepsis''' → A dangerous condition where the innate response (Inflammation) becomes "Global" and out of control, attacking the body's own organs.
