Protection against intracellular antigens
A) Innate immunity
B) Antibody-mediated immunity
C) Cell-mediated immunity
D) Both antibody-mediated and cell-mediated immunity
E) Innate immunity, antibody-mediated immunity, and cell-mediated immunity
Intracellular Antigens
Molecules located within cells that, when recognized as foreign by the immune system, can trigger an immune response.
Cell-Mediated Immunity
A type of immune reaction that is independent of antibodies, instead relying on the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the secretion of diverse cytokines when reacting to an antigen.
Antibody-Mediated Immunity
A type of adaptive immunity where B cells produce antibodies that target and neutralize foreign pathogens.
- Elucidate the distinction between the immunity provided by antibodies and that provided by cellular mechanisms.
- Recognize the role of various immune system components in defending against intracellular and extracellular pathogens.
