Self-antigens in the retina and central nervous system are the beneficiaries of a form of tolerance called:

Question

Quizplus · Accepted Answer

The term immune privilege refers to tissues or organs that are able to induce tolerance towards their own self-antigens, thus avoiding autoimmune reactions. The retina and central nervous system are immune privileged organs as they express self-antigens that are protected from the immune system. Therefore, the correct answer is D) immune privilege. Anergy refers to a state of unresponsiveness of immune cells to specific antigens, central tolerance is a process of negative selection of self-reactive T cells in the thymus, and clonal exhaustion refers to the depletion of a specific population of lymphocytes due to continuous activation. While each of these immune mechanisms can contribute to self-tolerance, immune privilege is the most relevant concept in relation to the retina and central nervous system.
