Question

Quizplus · Accepted Answer

Improper activation of B cells by self-antigens can lead to the production of autoantibodies, which can bind to and attack self-tissues, causing autoimmune diseases. Anergy refers to a state of unresponsiveness induced in lymphocytes by exposure to self-antigens without appropriate costimulation. Production of self-reactive T cells can also lead to autoimmune diseases. Allergic reactions are caused by exaggerated immune responses to harmless environmental substances. Peripheral tolerance is a mechanism that prevents self-reactive lymphocytes from attacking self-tissues.
