HLA typing of amniotic fluid cells for the prenatal determination of therapeutic transplantation options for a fetus affected with adenosine deaminase deficiency

Hydatidiform mole and HLA. Methods for HLA-A,B,C determination

The current Danish project on genetic markers and hydatidiform moles involves the examination of the histocompatibility between patient, spouse and molar tissue. For this purpose 2 techniques have been developed for HLA-A,B determination of molar tissue: (a) a cytotoxic microtechnique for the HLA typing of cultured molar cells, and (b) a microabsorption method using selected HLA antisera for the examination of frozen molar tissue. To date molar cell cultures or tissue have been examined in 22 of the cases. The results of HLA determination were compared with chromosomal markers to elucidate the origin of the haploid chromosome complements. In the cases examined a general agreement between the HLA-A,B type and the origin of the chromosomes was observed. The microabsorption method used seems to be less sensitive than the cytotoxic technique.

Organ transplantation and the immune response gene. Clinical correlations and donor requirements

Major gains have been made in the area of clinical organ transplantations due to recent studies concerning the human histocompatibility locus (HLA). These basic science findings, along with developments in clinical pharmacology have allowed for a much broader use of donor sources, and a significant prolongation in clinical life span for these transplantation recipients.
