Death of β-cells due to apoptosis is an important contributor to β-cell dysfunction in both type 1 and type 2 diabetes mellitus. Previously, we described participation of the Group VIA Ca(2+)-independent phospholipase A(2) (iPLA(2)β) in apoptosis of insulinoma cells due to ER stress. To examine whether islet β-cells are similarly susceptible to ER stress and undergo iPLA(2)β-mediated apoptosis,...
OBJECTIVE Environmental factors have been suggested to play an important role in the pathogenesis of type 1 diabetes. The aim of this study was to assess the influence of breast-feeding, vaccinations, and childhood viral diseases on the initiation of islet autoimmunity in early childhood. RESEARCH DESIGN AND METHODS Data were prospectively collected from questionnaires obtained at birth, at 9...
Chronic hepatitis C virus (HCV) infection is a leading cause of end-stage liver disease worldwide and HCV genotype 4 (HCV4) is predominant in African and Middle Eastern countries. It is well established that interferon-a (IFNa) treatment for HCV may trigger serum autoantibodies against pancreatic islet cells (ICA) in a subgroup of patients. Available data on the incidence of ICA during IFNa the...
In type 1 diabetes, the pancreatic islets are an important site for therapeutic intervention because immune infiltration of the islets is well established at diagnosis. Therefore, understanding the events that underlie the continued progression of the autoimmune response and islet destruction is critical. Islet infiltration and destruction is an asynchronous process, making it important to anal...
VP2 gene coding region of a vaccinal strain (D78) of infectious bursal disease virus (IBDV) was clonedin a eukaryotic expression vector, pSec Tag2A. The gene was placed downstream of Ig κ chain leadersequence, under the control of human cytomegalovirus (hCMV) immediate early enhancer and promoter. Theconstruct pSec Tag2A-VP2 was transfected in COS-7 cell line and the expression and secretion of...
BACKGROUND In both humans and rodents, glucose homeostasis is controlled by micro-organs called islets of Langerhans composed of beta cells, associated with other endocrine cell types. Most of our understanding of islet cell differentiation and morphogenesis is derived from rodent developmental studies. However, little is known about human islet formation. The lack of adequate experimental mode...
Background and Objective: β cell replacement therapy by pancreatic islet transplantation has become a promising treatment for type 1 diabetes. Medicago sativa L (Lucerne) from leguminosae family is known to exhibit hypoglycaemic activity both in animal and human studies. Most of these studies were concentrated on the effects of plant extracts on fasting glucose levels. Until now no researches h...
Introduction: Maintenance of neurogenesis depends on the function of some histone-modifying enzymes; including Enhancer of zeste homolog 2 (EZH2) and histone acetyltransferases (P300). The mechanism of epigenetic regulation and gene expression underlying the transition of human umbilical cord blood mesenchymal stem cells (hUCB-MSCs) into MNs has not been fully clarified. Methods: Two morphoge...
