What type of immunity occurs in a population when most people are immune and the disease can no longer spread?

(a)  

Autoimmune diseases occur when the immune system attacks its own body cells, producing ‘auto-antibodies’ that lock onto self antigens. For example (tick correct answer/s)

• Multiple sclerosis

• Downs's Syndrome

• Rheumatoid Arthritis

• Dwarfism

HIV binds to the CD4 receptors on ______________ Cells. This results in cytotoxic T-cells destroying these cells.

• Plasma B

• Dendritic

• Helper T

• Mast
