At this time, the only definitive treatment of hepatic failure is liver transplantation. However, transplantation has been limited by the severely limited supply of human donor livers. Alternatively, a regenerative medicine approach has been recently proposed in rodents that describe the production of three-dimensional whole-organ scaffolds for assembly of(More)
OBJECTIVE Macrophages play an important role in the pathogenesis of insulin resistance via the production of proinflammatory cytokines. Our goal is to decipher the molecular linkage between proinflammatory cytokine production and insulin resistance in macrophages. RESEARCH DESIGN AND METHODS We determined cytokine profiles in cultured macrophages and(More)
BACKGROUND The receptor for advanced glycation end-products (RAGE) has been suggested to modulate lung injury in models of acute pulmonary inflammation. To study this further, model systems utilizing wild type and RAGE knockout (KO) mice were used to determine the role of RAGE signaling in lipopolysaccharide (LPS) and E. coli induced acute pulmonary(More)
The generation of the pro-inflammatory cytokines IL-6, TNF-α, and IL-1β fuel the acute phase response (APR). To maintain body homeostasis, the increase of inflammatory proteins is resolved by acute phase proteins via presently unknown mechanisms. Hepatocyte growth factor (HGF) is transcribed in response to IL-6. Since IL-6 production promotes the generation(More)
BACKGROUND & AIMS Although the cells that contribute to pancreatic regeneration have been widely studied, little is known about the mediators of this process. During tissue regeneration, infiltrating macrophages debride the site of injury and coordinate the repair response. We investigated the role of macrophages in pancreatic regeneration in mice. (More)
Excessive endogenous glucose production contributes to fasting hyperglycemia in diabetes. FoxO6 is a distinct member of the FoxO subfamily. To elucidate the role of FoxO6 in hepatic gluconeogenesis and assess its contribution to the pathogenesis of fasting hyperglycemia in diabetes, we generated FoxO6 knock-out (FoxO6-KO) mice followed by determining the(More)
Previous studies by our group, using an experimental autoimmune thyroiditis (EAT) model in Strain 13 inbred guinea pigs, resulted in T cell-mediated delayed hypersensitivity; however, autoantibodies proved not to be cytotoxic to thyroid epithelial cells in the presence or absence of complement proteins. Albeit, T cell-mediated lymphocyte cytotoxicity began(More)
As a result of less than optimal outcomes the use of islet allografts as a standard insulin replacement therapy is limited to adults with a history of extreme glucose dysregulation and hypoglycemia unawareness. In this study, we examined the use of prophylactic immunotherapy to prevent islet allograft rejection in the absence of antirejection drugs. Our(More)
