Episode notes
Key Immune System Organs
- The immune system consists of key organs like the spleen, thymus, and lymph nodes, each with distinct roles.
- Lymph nodes act as essential hubs connected by lymphatic vessels for immune cell interaction and surveillance.
Innate Immunity's Rapid Defense
- The innate immune system acts fast with broad weapons like neutrophils and macrophages.
- It uses pattern recognition receptors to detect common microbial motifs but cannot recognize novel threats.
Adaptive Immunity's Unique Receptors
- The adaptive immune system creates unique receptors for every possible antigen via DNA rearrangement.
- Each T or B cell has a distinctive receptor allowing recognition of countless antigens, even new or never-before-seen ones.
