Which term describes a condition in which the immune system shows reduced responsiveness?

• A. Immunosuppression
• B. Autoimmunity
• C. Hypersensitivity
• D. Immunodeficiency

Answer: (A)

Immunosuppression is a state in which the immune system’s responsiveness is reduced. This can be purposeful, such as with medications that dampen immune activity to prevent transplant rejection or to treat autoimmune conditions, or it can result from illness or treatment that lowers immune function. It affects both cellular and humoral components, making the body less reactive to pathogens and vaccines. This fits the prompt best because it describes a downregulation of immune response rather than an overactive or misdirected one. Autoimmunity involves the immune system attacking the body’s own tissues, and hypersensitivity refers to an exaggerated immune reaction to harmless substances. Immunodeficiency refers to a deficiency that impairs the ability to mount an adequate immune response, often due to inherent defects or severe damage. Immunosuppression specifically captures the reduced responsiveness aspect described in the question.
