TRANSCRIPT
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 SystemKey words: antibodies, antigen, pathogen, antibody, B Cells, Memory T Cells
• A protein on a foreign object that stimulates the immune system to produce antibodies
• A virus, bacteria, toxin, ... That trigger the immune response
Antigen

Antibodies: proteins that recognize and bind to antigens.
Antibodies

Antibodies bind specific antigens
• Antibodies bind to antigens
• Pathogens clump together or agglutinate
• White Blood Cells (Macrophage) phagocite the antibody-antigen complex

Antibody mediated immunity
Objective: Learn the Antibody Response of the Immunity SystemKey words: antibodies, antigen, pathogen, antibody, B Cells, Memory Cells
• 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.
