What happens in an allergic response?
Examples of immune disorders:
- Psoriasis: In psoriasis, overactive immune system blood cells called T-cells collect in the skin. The immune system activity stimulates skin cells to reproduce rapidly, producing silvery, scaly plaques on the skin.
- Multiple Sclerosis: The immune system attacks nerve cells, causing symptoms that can include pain, blindness, weakness, poor coordination, and muscle spasms. The myelin sheath, which is a single cell whose membrane wraps around the axon, is destroyed with inflammation and scarring.
