You Are Immune Against Every Disease

Summary by Krater

An animated explanation of how the human immune system works, comparing innate and adaptive immunity, receptor diversity, and how cells are trained in the thymus to prevent autoimmune disease.

Answers: How does the human immune system work?

• Innate immunity vs adaptive immunity
• B cells and T cells
• Antibodies and receptors
• Protein puzzles and genetics
• Thymus selection process

What it concludes

• The human body has two immune systems: the innate immune system and the adaptive immune system.
• The adaptive immune system relies on a massive library of receptor combinations generated by mixing genetic code randomly.
• Around 98% of adaptive immune cells die in the thymus during training to prevent autoimmune disease.
