Also called c cell-mediated immunity. Determinant Part of the antigen molecule which binds to an antibody-combining site or to a receptor on T cells (see hapten and epitope). Differentiation antigen A cell surface antigenic determinant found only on cells of a certain lineage and at a particular developmental stage; used as an immunologic marker. Domain DR antigens MHC class II molecules found on B cells and antigen-presenting cells of humans. Defeminization The developmental process in which feminization is inhibited or suppressed. In females the term applies chiefly to defeminization of the brain attributed to a hormonal anomaly in prenatal life. Demasculinization The developmental process in which masculinization is inhibited or suppressed. In males, the term applies chiefly to demasculinization of the brain attributed to a hormonal anomaly in prenatal life. Depo-Provera The trade name of the hormone, medroxyprogesterone acetate, manufactured by Upjohn in the United States. The hormone is progestinic and antiandrogenic. It has several clinical applications, one of which is to help sex offenders gain personal governance of their sexuoerotic conduct. Diethylstilbestrol A synthetic drug, not a steroid, that acts as a female sex hormone. Structural variants include dipropionate, dilaurate, and dibutyrate esters, and C14-diethylstilbestrol dibutyrate, the radioactive form used only for special investigative procedures.
