Abstract
The number of Ia molecules accessible at the surface of a cell could be related to the stage of differentiation and to the functional status of that cell. We have measured the level of Ia expressed on various normal and leukemic human lymphocytes using monoclonal antibody 21w4 which recognizes a non-polymorphic epitope of human Ia (1,2). Our results with ALL and CLL do not support a correlation between stage of differentiation and level of Ia. Furthermore PHA-activated T cells and tonsillar B cells express the highest amounts of Ia.
