title: Close genetic relationships between determinants of the HLA-D region detected by MLR-I, MLR-II, and B-lymphocyte serology.
abstract: The human Ia equivalent (Ly-Li system) or a very closely linked gene plays a preponderant role in secondary MLR, and also has an additive effect on the intensity of the primary MLR. PLTs developed in Li phenoidentity seem to detect still other determinants.
