Genomic DNA fragments encompassing the human Thy-1 or mouse Thy-1.1 gene have been microinjected into pronuclei of mouse embryos homozygous for the Thy-1.2 allele. In the resulting transgenic mice, the human gene is expressed in a pattern characteristic of normal human tissues, and is not influenced by the pattern of endogenous mouse Thy-1 expression. The(More)
OBJECTIVE To review the main risk factors for ischemic heart disease and preventive strategies during childhood. SOURCES Medline review between 1985 and 2001, and key references from the studies evaluated. CONCLUSIONS Preventive interventions that may start in childhood are described for risk factors such as hyperlipidemias, obesity, smoking and(More)
We have isolated and sequenced cDNA clones corresponding to the DR beta 1 and DR beta 2 loci from two homozygous B-cell lines typed as DR7 (Burkhart) and DR9 (ISK). These nucleotide sequences were compared to beta 1 and beta 2 chains of other DR haplotypes. The first-domain sequences of beta 2 chains are identical in DR4 and DR7 haplotypes. In addition,(More)
A cDNA library was constructed from a DR7, DRw53, DQw2 homozygous cell line, cDNA clones corresponding to DR beta and DQ beta chains were isolated, and the nucleotide sequences of the polymorphic first domains of these chains were determined. A novel screening strategy allowed rapid and simple identification of cDNA clones corresponding to both DR beta(More)
We studied the humoral response of mice immunized with soluble CD4-rgp120 complex, testing polyclonal and monoclonal antibodies (mAbs) with the aim of identifying molecular changes that take place after the first interaction between human immunodeficiency virus and the cell surface. The antisera had a paradoxically high syncytia-blocking titer associated(More)
Complementary DNA (cDNA) clones encoding beta chains of the DR and DQ regions and alpha chains of the DQ region were isolated and sequenced from four homozygous DR4 cell lines of different HLA-D types: GM3103(Dw4), FS(Dw10), BIN(Dw14), and KT3(Dw15). When compared with each other and with a previously published sequence from a DR4 (Dw13 cell line), the(More)
