Mono(ADP-ribosyl)transferases regulate the function of target proteins by attaching ADP-ribose to specific amino acid residues in their target proteins. The purpose of this study was to determine the structure, chromosomal localization, and expression profile of the gene for mouse ecto-ADP-ribosyltransferase ART5. Southern blot analyses indicate that Art5(More)
Two homozygous lines of transgenic NOD/Lt mice expressing MHC class II I-E molecules at quantitatively different levels were utilized to study mechanisms of I-E-mediated diabetes prevention. In line 12, I-E expression on APC at levels comparable with that in BALB/cByJ controls conferred only partial diabetes resistance. In line 5, greater than normal I-E(More)
A single injection of syngeneic islet cells into the thymus of 4-week-old NOD/Lt female mice strongly retards diabetogenesis. The present study used the intrathymic route of antigen administration to compare the relative efficacy of peptides/proteins derived from two major candidate pancreatic beta-cell autoantigens, insulin and GAD65, to modulate(More)
Although expressed at very low levels in islets of NOD mice, GAD65 is a candidate islet autoantigen. Two transgenic lines of NOD/Lt mice expressing high levels of human GAD65 from a rat insulin promoter were generated. Transgenes were integrated on proximal chromosome 15 of the A line and on the Y chromosome of the Y line. Transgenic A-line mice were(More)
The answer to the question posed by the title (is there a relationship between aberrant Art gene expression and IDDM pathogenesis in NOD mice?) remains elusive. Conclusions are currently based almost entirely upon analysis of mRNA transcript levels rather than on T-cell-specific mono-ADP ribosylation activities. Our unpublished data, as well as data(More)
