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

Antigen
• A protein on a foreign object that stimulates the immune system to
produce antibodies
• A virus, bacteria, toxin, ... That trigger the immune response

Antibodies
Antibodies: proteins that recognize and bind to antigens.

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

Antibody mediated immunity
• B Lymphocytes mature in bone marrow.
• B Lymphocytes or B cells are responsible for the antibodymediated immunity. They produce antibodies when
exposed to specific antigens.
• T Lymphocytes mature in the thymus gland.
• T Cells are responsible for cell-mediated immunity.
