PHENOTYPIC EXPRESSIONS OF THE MAJOR HISTOCOMPATIBILITY LOCUS IN MAN (HL-A): LEUKOCYTE ANTIGENS AND MIXED LEUKOCYTE CULTURE REACTIVITY

摘要

The evidence is reviewed that a single genetic system, the major histocompatibility locus in man, HL-A , determines most of the antigens measured by presently available leukocyte isoantisera, and also controls reactivity in one-way mixed leucocyte culture tests. Studies in 12 families are presented to support this conclusion. Some interesting exceptions to the general typing—MLC tests correlation are presented and discussed.
