Multiple Choice

What is immunological tolerance?

The ability of the immune system to remove lymphocytes that recognize and attack foreign antigens.

The ability of the immune system to differentiate between self and non-self antigens.

The ability of the immune system to create antibodies that most effectively bind foreign antigens.

The ability of the immune system to tolerate a certain amount of pathogens before triggering an immune response.

Verified step by step guidance

Understand the concept of immunological tolerance: It is the immune system's ability to recognize and not attack the body's own cells, distinguishing between self and non-self antigens.

Differentiate between self and non-self antigens: Self antigens are the body's own proteins and molecules, while non-self antigens are foreign substances that can trigger an immune response.

Recognize the importance of immunological tolerance: It prevents the immune system from attacking the body's own tissues, which is crucial for preventing autoimmune diseases.

Consider the mechanisms of tolerance: Central tolerance occurs in the thymus and bone marrow where self-reactive lymphocytes are eliminated, while peripheral tolerance occurs in the body's tissues to control any self-reactive cells that escape central tolerance.

Evaluate the options given: The correct answer is the ability of the immune system to differentiate between self and non-self antigens, as this is the essence of immunological tolerance.
