UNLABELLED Langerhans cell histiocytosis (LCH), which is a rare granulomatous pediatric disease of unknown etiology, is characterized by the idiopathic proliferation and accumulation of abnormal and clonal Langerhans cells or their marrow precursors, resulting in localized, solitary or multiple destructive lesions. These lesions are most commonly eosinophilic granuloma, which are found in crani...
AIM To identify the types of endocrine cells in the pancreas of the Sunda porcupine (Hystrix javanica) and its immunolocalization. MATERIALS AND METHODS Five adult H. javanica were used without sexual distinction. The presences of endocrine cells (glucagon, insulin, somatostatin, and pancreatic polypeptide [PP]) in pancreatic tissues were detected using the avidin-biotin-peroxidase complex me...
objective(s): the link between a hyperglycemic intrauterine environment and the development of diabetes later in life has been observed in offspring exposed to gestational diabetes mellitus (gdm), but the underlying mechanisms for this phenomenon are still not clear. reduced β-cells mass is a determinant in the development of diabetes (type 1 and type 2 diabetes). some recent studies have provi...
Key papers in scientific literature sometimes bring a definitive resolution to a long-awaited issue. Others may be far less decisive but importantly implore us to question the fitness of prevailing models. So it is that a paper in this issue by F. Geissmann and colleagues (1), albeit subject to some variety of interpretation, nevertheless compels us to reexamine the widely accepted idea that mi...
Dendritic cells and their precursors express PPAR-gamma, whose stimulation has inhibitory effects on the maturation and function of dendritic cells in vivo. Dendritic cells can differentiate in vitro from CD133+ progenitors; the influence of PPAR-gamma stimulation on this process is unknown. We have addressed the effect of PPAR-gamma agonist rosiglitazone, at a concentration as used in clinics,...
