  3. 7. Blocks viral binding sites; cotes bacterial toxins
  4. 11. What is another name for antibodies?
  5. 12. Blood serum contains a type of antibody which is a mixture of antibodies which bind to multiple epitopes. What is the name of these antibodies?
  6. 13. a transmembrane glycoprotein co-receptor that assists the T cell receptor
  7. 14. T-helper cells release cytokines such as interleukin-2, which are signalling molecules/ligands that bind to receptors and trigger a reaction. What type of blood cells do they regulate?
