Question

Quizplus · Accepted Answer

The process in which lymphocytes that recognize self-antigens are prevented from being activated is called clonal anergy. This occurs when a T or B cell encounters a self-antigen without appropriate costimulatory signals, leading to inactivation instead of activation. Clonal deletion involves the elimination of self-reactive lymphocytes during development in the thymus or bone marrow. Clonal selection is the process by which antigen-specific lymphocytes are selected to expand and differentiate upon encountering their corresponding antigen. Apoptosis is a programmed cell death mechanism that may be triggered in lymphocytes for various reasons, including failure to respond to antigen stimulation.
