Abstract
An informative family, in which parents shared HLA-Dw and Ia-like DRw (Ly-Li) antigens, was used to produce PLTs between members either phenoidentical for both Dw and DRw determinants or incompatible for Dw specificities only. These PLTs were restimulated by members of the family: two PLTs, although in DRw identity, reacted against members of the family bearing one maternal (c) and/or one paternal (a) haplotype. A third PLT also developed in DRw identity reacted with members bearing the other maternal (d) haplotype. Population studies with one of these PLTs did not show any correlation with Dw or DRw specificities. Family studies are in keeping, but do not demonstrate an HLA linkage. The data suggest that, along with the stimulating products (PLA) identical or closely related to the DRw determinants, other stimulating products (PLB), also probably HLA-linked, exist. Furthermore, one of the PLTs was produced without a primary MLR.
