Long-term treatment with glucagon-like peptide (GLP)-1 or its analog can improve insulin sensitivity. However, continuous administration is required due to its short half-life. We hypothesized that continuous production of therapeutic levels of GLP-1 in vivo by a gene therapy strategy may remit hyperglycemia and maintain prolonged normoglycemia. We produced(More)
Type 1 diabetes results from insulin deficiency caused by destruction of pancreatic beta cells. Glucagon-like peptide (GLP)-1 stimulates beta cell growth and differentiation. To determine whether continuous expression of GLP-1 in vivo can regenerate beta cells and remit type 1 diabetes in mice for a prolonged time, we constructed an adenoviral vector(More)
To investigate whether the local production of glucagon-like peptide-1 (GLP-1) in the intestine can differentiate intestinal stem/progenitor cells into insulin-producing cells, we intra-intestinally injected a recombinant adenovirus expressing GLP-1 (rAd-GLP-1) into diabetic mice. There were no significant differences in body weight or food intake between(More)
Patients with localized aggressive periodontitis have type-1 cytokines in gingival crevicular fluid and high titers of IFN-gamma-dependent IgG2 reactive with P. gingivalis in gingival crevicular fluid and serum. Localized aggressive periodontitis monocytes spontaneously differentiate into dendritic cells that can stimulate IFN-gamma production by NK cells.(More)
Previous studies have shown that adenosine agonists acting at A-2 receptors inhibit platelet aggregation. Since an increase in cytosolic Ca2+ concentration (delta [Ca2+]i) is closely associated with the time frame of platelet aggregation, we have examined the effect of adenosine receptor function on induced increases of [Ca2+]i by a potent platelet(More)
