The immune system is both guardian and potential adversary — capable of extraordinary protection, and profound harm when dysregulated. This chapter offers a framework for understanding how immune responses arise, adapt, and sometimes turn inward.

In this audio exploration, we trace the balance between innate and adaptive immunity, inflammation and tolerance, defence and repair. You’ll hear how immune dysfunction presents clinically — through infection, autoimmunity, allergy, and chronic inflammation — and why these patterns matter across every specialty.

This chapter reframes immunology as a system of relationships rather than reactions: a constantly negotiated truce between self and threat.
