Continuous glucose monitoring associated with intensive insulin regimens represents a useful tool to lower HbA1c in selected adults with type 1 diabetes. Recent randomized controlled trials demonstrated greater glycemic benefits in type 1 diabetic patients treated with multiple daily injections of insulin and continuous glucose monitoring over usual care. These positive outcomes, however, are counter-balanced by several limitations that restrict the use of continuous glucose monitoring in the real life, including the apparent lack of benefits in children and pregnant diabetic women, the high cost, the stringent patients' selection, and the presence of a multi-disciplinary team with specific expertise...

AIMS/HYPOTHESIS: Glucagon-like peptide-1 (GLP-1) receptor agonists are currently used for the treatment of type 2 diabetes. Their main mechanism of action is enhancement of glucose-induced insulin secretion (from increased beta cell glucose sensitivity) and inhibition of glucagon secretion. The latter has been demonstrated to account for about half of their blood glucose-lowering activity. Whereas the effect of GLP-1 on insulin secretion is clearly dependent on ambient glucose concentrations and has been described in detail, the mechanism responsible for the inhibitory effect of GLP-1 on glucagon secretion is heavily debated...

AIMS/HYPOTHESIS: Shift-work is associated with circadian rhythm disruption and an increased risk of obesity and type 2 diabetes. We sought to determine the effect of rotational shift-work on glucose metabolism in humans. METHODS: We studied 12 otherwise healthy nurses performing rotational shift-work using a randomised crossover study design. On each occasion, participants underwent an isotope-labelled mixed meal test during a simulated day shift and a simulated night shift, enabling simultaneous measurement of glucose flux and beta cell function using the oral minimal model...

Swietenia humilis Zucc. (Meliaceae) seeds are used in Mexico for the treatment of type 2 diabetes mellitus. Mexicanolides are the main hypoglycemic and antihyperglycemic compounds of the species. This study was conducted to investigate the antihyperalgesic effect of an aqueous extract of the seeds of Swietenia humilis (SHAE) and of mexicanolide 2-hydroxy-destigloyl-6-deoxyswietenine acetate (1), using the formalin test in mice. The antihyperalgesic actions of SHAE and mexicanolide 1, as well as its possible transductional activity, were assessed in nicotinamide-streptozotocin (NA-STZ) hyperglycemic mice...

Abnormalities in the hyperbolic relationship between insulin sensitivity and insulin secretion may cause oxidative stress and non-enzymatic glycation, resulting in an increased risk of type 2 diabetes. Here, we performed a 14-week study to investigate the effects of ethanolic extract of Mori ramulus (MRE; 0, 800, and 1600mg/kg body weight) and its signature component oxyresveratrol (OXY; 800mg/kg body weight) on β-cell dysfunction and insulin resistance in C57BLKS/J db/db mice fed with a high-fat diet. Compared with the diabetic control group, the high-dose MRE group showed a significant decrease in fasting blood glucose (p=0...

Autoimmune regulator (Aire) plays an indispensable role in maintaining central immune tolerance by promoting the ectopic expression of tissue-restricted antigens (TRAs) in medullary thymic epithelial cells (mTECs) and dendritic cells (DCs), which lead to the deletion of autoreactive T cells or the induction of Tregs and consequently prevent autoimmune disease development. Curing autoimmune diseases has always been a challenge. DC-based immunotherapy represents a new and effective method to establish tolerance...

BACKGROUND AND AIMS: Individuals with type 1 diabetes mellitus are at high risk of developing atherosclerotic cardiovascular disease, but the underlying mechanisms by which type 1 diabetes accelerates atherosclerosis remain unknown. Increased retention of low-density lipoprotein (LDL) in atherosclerosis-prone sites of the diabetic vascular wall has been suggested, but direct evidence is lacking. In the present study, we investigated whether retention of LDL is increased in atherosclerotic-prone areas using a murine model of type 1 diabetes...

Segmented filamentous bacterium (SFB) a gram-positive, anaerobic, and intestinal commensal organism directly influencesthe development of Th17 helper cells in the small intestine of mice. In NOD mice, SFB colonization interferes with the developmentof type 1 diabetes (T1D), a T-cell-mediated autoimmune disease, suggesting that SFB may influence Th17 cells to inhibit Th1populations associated with the anti-β-cell immune response. This effect is a serious concern for investigators who use NOD micefor diabetes research because the expected incidence of disease decreases markedly when they are colonized by SFB...

REVIEW
Simon E Regnell, Åke Lernmark
Underlying type 1 diabetes is a genetic aetiology dominated by the influence of specific HLA haplotypes involving primarily the class II DR-DQ region. In genetically predisposed children with the DR4-DQ8 haplotype, exogenous factors, yet to be identified, are thought to trigger an autoimmune reaction against insulin, signalled by insulin autoantibodies as the first autoantibody to appear. In children with the DR3-DQ2 haplotype, the triggering reaction is primarily against GAD signalled by GAD autoantibodies (GADA) as the first-appearing autoantibody...

CD38 is an activation marker that is present on recently activated T cells, but absent on resting memory T cells. In this study, we show that CD45RO(+)CD38(+) β cell Ag-specific CD4(+) T cells were present at higher frequencies in type 1 diabetes subjects compared with those in healthy subjects. These results imply an ongoing β cell immunity years after onset of diabetes and suggest these activated T cells have an active role in the disease process. The Ag specificities of these activated T cells were determined by a novel CD154 T cell epitope mapping assay...
