Examples
- The human immune reaction is an incredibly complex system, composed of multiple cell types, tissues, and organs that work together to defend the body against pathogens.
- When a person receives a vaccine, their immune reaction is triggered, and the body produces antibodies that will protect against future infections.
- In autoimmune diseases, the immune reaction mistakenly targets and damages the body's own cells and tissues, thinking they are foreign invaders.
- The immune reaction to a transplanted kidney requires the patient to take immunosuppressive medication to prevent the body from rejecting the new organ.
- Research has shown that the immune reaction can be tailored to target and destroy cancer cells, a promising new approach in the fight against the disease.
