Extracellular adenosine (Ado) has been implicated as central signaling molecule during conditions of limited oxygen availability (hypoxia), regulating physiologic outcomes as diverse as vascular leak, leukocyte activation, and accumulation. Presently, the molecular mechanisms that elevate extracellular Ado during hypoxia are unclear. In the present study,(More)
Monocyte-specific monoclonal antibodies (7) were used to compare the efficacy of monocytes and dendritic cells as accessory or stimulator cells for human T cell replication. Both unfractionated and plastic-adherent mononuclear cells were first treated with a cytolytic antimonocyte antibody that kills greater than 95% of monocytes but not dendritic cells.(More)
Myotonic dystrophy (DM) is the most common form of adult onset muscular dystrophy, with an incidence of approximately 1 in 8500 adults. DM is caused by an expanded number of trinucleotide repeats in the 3'-untranslated region (UTR) of a cAMP-dependent protein kinase (DM protein kinase, DMPK). Although a large number of transgenic animals have been generated(More)
Highly polymorphic repeated DNA sequences were detected at the end of the long arm of human chromosome 18 by a recombinant DNA probe containing 56 bp of human DNA (pERT25). This was shown by hybridization of pERT25 to DNA from a panel of human X rodent somatic cell hybrids, by dot blot hybridization to flow-sorted human chromosomes, and by in situ(More)
