Medical Definition of anergy

: a condition in which the body's immune system fails to react to an antigen : immunological hyporesponsiveness Specific anergy is lack of reactivity to an individual antigen, while generalized (nonspecific) anergy is the inability to react to any antigen.— Harriet Kitzman et al., The Journal of the American Medical Association, 19 Apr. 2000 By deliberately throwing cells into anergy, researchers also hope to control allergies and certain autoimmune diseases like rheumatoid arthritis, in which white blood cells attack the body's connective tissue in the joints.— Gina Kolata, The New York Times, 22 Oct. 1991
