    Notes: Abstract Longevity varies between and within species. The existence of species-specific limit to human life-span and its partial heritability indicate the existence of genetic factors that influence the ageing process. Insight into the nature of these genetic factors is provided by evolutionary studies, notably the disposable soma theory, which suggests a central role of energy metabolism in determining life-span. Energy is important in two ways. First, the disposable soma theory indicates that the optimum energy investment in cell maintenance and repair processes will be tuned through natural selection to provide adequate, but not excessive, protection against random molecular damages (e.g. to DNA, proteins). All that is required is that the organism remains in a sound condition through its natural expectation of life in the wild environment, where accidents are the predominant cause of mortality. Secondly, energy is implicated because of the intrinsic vulnerability of mitochondria to damage that may interfere with the normal supply of energy to the cell via the oxidative phosphorylation pathways. Oxidative phosphorylation produces ATP, and as a by-product also produces highly reactive oxygen radicals that can damage many cell structures, including the mitochondria themselves. Several lines of evidence link, on the one hand, oxidative damage to cell ageing, and on the other hand, energy-dependent antioxidant defences to the preservation of cellular homeostasis, and hence, longevity. Models of cellular ageing in vitro allow direct investigation of mechanisms, such as oxidative damage, that contribute to limiting human life-span. The genetic substratum of inter-individual differences in longevity may be unraveled by a two-pronged reverse genetics approach: sibling pair analysis applied to nonagenarian and centenarian siblings, combined with association studies of centenarians, may lead to the identification of genetic influences upon human longevity. These studies have become practicable thanks to recent progress in human genome mapping, especially to the development of microsatellite markers and the integration of genetic and physical maps.

    Notes: Abstract Human HLA cDNA probes were used to analyze the restriction fragment length polymorphism (RFLP) of the SLA major histocompatibility complex in swine. Cellular genomic DNA from 19 SLA homozygous pigs representing 13 different haplotypes was digested with restriction endonucleases Eco RI, Hind III, or Bam H1, separated by electrophoresis, and transferred onto diazobenzyloxymethyl paper by the Southern blot technique. The blots were probed with 32P-labeled class I or beta-DR class II cDNA. Depending on the haplotypes and the endonucleases used, seven to ten restriction fragments hybridized with the class I probe, and five to seven with the beta-DR probe. Their sizes ranged from 3.4 to 22 kilobase-pairs. Few bands were common to all 13 haplotypes. With all but one haplotype, identical autoradiogram patterns were obtained from unrelated, but phenotypically SLA-identical pigs, suggesting that most of the RFLP revealed were controlled by the SLA region. Further polymorphism was found in a group of seven unrelated pigs which typed serologically as SLA A15 CI B18 homozygotes but could be divided into two subgroups, with five animals in one subgroup and two in the other, when the genomic DNA was hybridized with the class I probe. When the class 11 beta-DR probe was tested on the same seven pigs, another subdivision was seen, and this correlated with MLR data. These results demonstrate that HLA class I and class II probes can be used to identify certain well-established SLA haplotypes and to identify subclasses within at least one SLA haplotype.

    Notes: Abstract mRNAs for the two chains of the HLA-DQ molecule were analyzed, in particular the DQα mRNA whose polymorphism had previously been suggested (Schenning et al. 1984). Northern blot transfers of the mRNA of 12 LCLs and of B lymphocytes from a healthy donor were carried out. We report that a length polymorphism of DQα mRNA exists, and we show that it can be correlated with serologically defined specificities (DQwl, DRw53, DR3 + 5). This correlation could be explained by a linkage disequilibrium, as these specificities are considered to be different from those carried by the DQ molecule (except for the DQw1 specificity).

    Notes: Abstract Two variants of the serologically defined HLA-DR2 specificity have been reported: DR2 long and DR2 short. Distinct HLA-DR2-associated Dw subtypes have been described at the cellular level. In the Israeli population, DR2 individuals may be grouped into three clusters: DR2/Dw2, DR2/Dw12, and DR2/Dw“AZH”. A new approach for the study of the polymorphism of HLA class II genes is to investigate restriction endonuclease fragments obtained from genomic DNA with specific class II cDNA probes. Previous analysis of DQ β restriction endonuclease fragments subdivided the DR2 haplotypes into two subsets: a DQR1-positive subset and a DQR2.6-positive subset. These two subsets behave in the population as alleles that split HLA DQwl. In the present study, we have analyzed class II DQ α , DQ β , and DR β restriction fragment length polymorphism (RFLP) in HLA-DR2/Dw-typed healthy, unrelated Israeli individuals, as well as in 11 French HLA-DR2 insulin-dependent diabetes mellitus (IDDM) patients and 11 French DR-matched controls. Three DQ β allelic clusters (DQR2.6, DQR1, and DQR12) were observed among the DR2 haplotypes and clearly correlated with Dw2, Dw“AZH”, and Dw12, respectively. The vast majority of the DR2 IDDM patients (9 out of 11) fit into the DQR1 cluster which correlates with Dw“AZH”, while only two patients (2 out of 11) belong to the DQR2.6 cluster (Dw2-like). In contrast, among 11 DR-matched healthy controls, 9 belonged to the DQR2.6 cluster and only 2 belonged to the DQR1 cluster. These studies establish the correlation between the DR2-associated Dw subtypes with specific RFLPs, and indicate that the frequency of the DQR1 subset which correlates with Dw“AZH” is increased in DR2 IDDM patients.

    Notes: Abstract In the present report, we used serological, cellular, and restriction fragment length polymorphism (RFLP) to investigate the DR1 haplotype in the Israeli population. We describe an Israeli homozygous typing cell (HTC), HLA-Dw“LVA”, which defines a new lymphocyte-activating determinant associated with Bw65, DR1 and distinct from Dwl. The parents of this donor, non-Ashkenazi Algerian Jews, are first cousins and share HLA-Cw8, Bw65, BfS, DR1, DQw1, DPw4. No specificity could be assigned to HLA-Dw“LVA” using the 91 Ninth Workshop HTCs. Two families and forty unrelated DR1 individuals were studied with Dw“LVA” and a panel of DR1/Dw1 HTCs. HLA-Dw“LVA” showed segregation as a single determinant within families. This new specificity was present in 24 out of 40 (60%) unrelated DR1 individuals, indicating that in the Israeli population Dw“LVA” is the main lymphocyte-defined determinant associated with the serologically defined DRI specificity, in contrast to non-Jewish Caucasoids where DR1 is significantly associated with Dw1. The vast majority of Dw“LVA”-positive carriers were also Bw65 carriers, indicating that Bw65, DR1, Dw“LVA” may represent a typical allele combination in the Israeli population. The RFLP analysis established the correlation of certain RFLPs with Dw1 and Dw“LVA”. In addition, we describe a cluster of RFLPs that may correspond to a new Dw subtype associated with DR1, for which no serological and cellular reagents have been described so far.

    Notes: Summary Friedreich ataxia (FA) is a severe autosomal recessive neurodegenerative disease. The defective gene has been previously assigned to chromosome 9q13-q21 by demonstration of tight linkage to the two independent loci D9S15 and D9S5. Linkage data indicate that FRDA is at less than 1 cM from both markers. Previous physical mapping has shown that probes defining D9S15 (MCT112) and D9S5 (26P) are less than 260kb apart and are surrounded by at least six CpG clusters within 450 kb, which might indicate the presence of “candidate” genes for FA. We isolated and characterized a 530 kb YAC (yeast artificial chromosome) contig that contains five of the CpG clusters. The YACs were used to search for new polymorphic markers needed to map FRDA precisely with respect to the cloned segment. In particular, we found a (CA)n microsatellite polymorphism, GS4, that detects 13 alleles with a PIC value of 0.83 and allows the definition of haplotypes extending over 310kb when used in combination with polymorphic markers at D9S5 and D9S15.

    Notes: Abstract Four cDNA probes for the human major histocompatibility complex (MHC) were used to investigate the sheep MHC, in conjunction with serological typing for ovine lymphocyte antigen (OLA). Lymphocytes from a family (two parents and five offspring) of Romanov sheep were subjected to genomic DNA digestion by the restriction endonuclease Eco RI, followed by gel electrophoresis. A single Southern blot representing all seven individuals was then consecutively hybridized with the class I, alpha-DC, beta-DR, and C4 probes, which were originally designed to identify HLA class I, class II (DC and DR), and C4 products, respectively. Using each of the three class I/class II probes, several bands showing DNA polymorphism were detected. The segregation of these bands in the five offspring exactly paralleled the OLA haplotype segregation established by serological typing. A further eight individuals carrying haplotypes which were phenotypically identical to those in the above-mentioned family showed bands in the corresponding positions when tested with the same three probes. Using the C4 probe, no polymorphism was detected in these fifteen individuals.
