Study Notes

CD4 Cells and Cytokines

  • Th2 CD4 cells characteristically produce IL-4, which provides help for antibody production, but not IFN-gamma.
  • IL-1 is produced by both Th1 and Th2 cells.

Cytokines and Acute Phase Proteins

  • IL-6 is the cytokine that can mediate the release of acute phase proteins from the liver.

Antibody Affinity

  • The affinity of an antibody can be determined by measuring the amount of antibody bound at various antigen concentrations.
