1 Characteristics of the Specific Immune Response It recognizes and targets “specific” pathogens or foreign substances. It has a “memory,” the capacity to store information from past exposures to respond more quickly to future invasions of the same pathogen. It protects the entire body, the immunity is NOT linked to the site of infection. Objective: Learn the Antibody Response of the Immunity System Key words: antibodies, antigen, pathogen, antibody, B Cells, Memory T Cells

2 A protein on a foreign object that stimulates the immune system to produce antibodies A virus, bacteria, toxin,... That trigger the immune response Antigen Objective: Learn the Antibody Response of the Immunity System Key words: antibodies, antigen, pathogen, antibody, B Cells, Memory T Cells

3 Figure 9.7 Antibodies: proteins that recognize and bind to antigens. Antibodies Objective: Learn the Antibody Response of the Immunity System Key words: antibodies, antigen, pathogen, antibody, B Cells, Memory T Cells

4 Antibodies bind specific antigens Antibodies bind to antigens Pathogens clump together or agglutinate White Blood Cells (Macrophage) phagocite the antibody-antigen complex Antibody-Antigen Complex Objective: Learn the Antibody Response of the Immunity System Key words: antibodies, antigen, pathogen, antibody, B Cells, Memory T Cells

5 B Lymphocyte or B cells Objective: Learn the Antibody Response of the Immunity System Key words: antibodies, antigen, pathogen, antibody, B Cells, Memory T Cells

6 Antibody mediated immunity Objective: Learn the Antibody Response of the Immunity System Key words: antibodies, antigen, pathogen, antibody, B Cells, Memory T Cells

7 Antibody mediated immunity Objective: Learn the Antibody Response of the Immunity System Key words: antibodies, antigen, pathogen, antibody, B Cells, Memory Cells

8 B Lymphocytes mature in bone marrow. B Lymphocytes or B cells are responsible for the antibody- mediated immunity. They produce antibodies when exposed to specific antigens. T Lymphocytes mature in the thymus gland. T Cells are responsible for cell-mediated immunity. Antibody mediated immunity Objective: Learn the Antibody Response of the Immunity System Key words: antibodies, antigen, pathogen, antibody, B Cells, Memory T Cells
