title: Medial histocompatibility antigens.
abstract: Medial histocompatibility (H) antigens are weak H antigens, recognized by unrestricted T cells; they differ thus from both major and minor H antigens. An example, Qed-1, is described in detail, and other known medial H antigens of the mouse are reviewed. The structural and genetic relationships of major and medial H antigens and their role in T cell recognition are discussed.
