In individuals with normal glucose tolerance, β-cell function and insulin sensitivity gradually decrease with a deterioration in the lipid profile. Not only fasting TG but also postprandial TG concentrations are independent risk factors for impaired β-cell function and insulin resistance (Journal of Diabetes Investigation)

Diabetes: Concepts of β-Cell Organ Dysfunction and Failure Would Lead to Earlier Diagnoses and Prevention
There is a potential to identify both T2D and T1D at stages well before the onset of currently recognized clinical disease (Diabetes)
Probing β-Cell Biology in Space and Time
Scientists must be able to investigate (and visualize) short- and long-lived events within the pancreas and β-cells. Current technological advances in microscopy are able to bridge multiple spatiotemporal scales in biology to reveal the complexity and heterogeneity of β-cell biolog (Diabetes)
Imatinib therapy for patients with recent-onset type 1 diabetes: a multicentre, randomised, double-blind, placebo-controlled, phase 2 trial
A 26-week course of imatinib preserved β-cell function at 12 months in adults with recent-onset type 1 diabetes. Imatinib might offer a novel means to alter the course of type 1 diabetes (The Lancet Diabetes & Endocrinology)
Association of glycemia with insulin sensitivity and β-cell function in adults with early type 2 diabetes on metformin alone
Glycemia is strongly associated with β-cell dysfunction in adults with early T2DM treated with metformin alone. Efforts to improve glycemia should focus on interventions aimed at improving β-cell function (Journal of Diabetes and Its Complications)
Anti-interleukin-21 antibody and liraglutide for the preservation of β-cell function in adults with recent-onset type 1 diabetes: a randomised, double-blind, placebo-controlled, phase 2 trial
The combination of anti-IL-21 and liraglutide could preserve β-cell function in recently diagnosed type 1 diabetes. The efficacy of this combination appears to be similar to that seen in trials of other disease-modifying interventions in type 1 diabetes, but with a seemingly better safety profile (The Lancet Diabetes & Endocrinology)
Residual β cell function in long-term type 1 diabetes associates with reduced incidence of hypoglycemia
β Cell function can persist in long-duration T1DM. With a peak C-peptide concentration of >0.03 nmol/L, we observed clinically meaningful reductions in the prevalence of severe hypoglycemia (Journal of Clinical Investigation)
A Randomized Trial of Insulin Glargine plus Oral Hypoglycemic Agents versus Continuous Subcutaneous Insulin Infusion to Treat Newly Diagnosed Type 2 Diabetes
In conclusion, short-term intensive therapy with basal insulin plus OHAs showed comparable benefits to CSII in terms of overall glycemic control and improvement in β-cell function in newly diagnosed patients with type 2 diabetes mellitus and is a possible option for treating newly diagnosed patients with type 2 diabetes (Journal of Diabetes Research)
Long-term effects on glycaemic control and β-cell preservation of early intensive treatment in patients with newly diagnosed type 2 diabetes
The findings indicate that outpatient clinic-based IIT to ensure euglycaemia in newly diagnosed patients with T2DM might be an effective initial therapeutic option for improvements in β-cell function and glycaemic control over the long term, without serious adverse events (Diabetes, Obesity and Metabolism)
Beta cell function and ongoing autoimmunity in long-standing, childhood onset type 1 diabetes
There is evidence of ongoing autoimmunity in the majority of individuals with longstanding diabetes. Endogenous insulin secretion continues for many years after diagnosis in individuals diagnosed with autoimmune-mediated type 1 diabetes above age 5. These findings suggest that some beta cells are protected from continued autoimmune attack in longstanding type 1 diabetes (Diabetologia)
β-Cell death is decreased in women with gestational diabetes mellitus
These results demonstrate that β-cell death is reduced in women with GDM. This reduction is associated with impaired insulin production and hyperglycemia, suggesting that β-cell death does not contribute to GDM during the 2nd and 3rd trimester of pregnancy (Diabetology & Metabolic Syndrome)
Exenatide improves β-cell function up to 3 years of treatment in patients with type 2 diabetes
Compared with GLAR, EXE improved the parameters of β-cell function, especially insulin secretion at 8 mmol/L glucose and β-cell glucose sensitivity, which was sustained during the 3-year treatment period (EJE)
β-cell dysfunction in women with previous gestational diabetes is associated with visceral adipose tissue distribution
Women with GDM are at increased risk of developing pre-diabetes and have a decreased β-cell function 5 years post-partum that is associated with increased visceral fat mass (European Journal of Endocrinology)
Lipotoxic Stress Induces Pancreatic β-Cell Apoptosis through Modulation of Bcl-2 Proteins by the Ubiquitin-Proteasome System
Our results suggest that targeting the UPS and Bcl-2 protein expression may be a valuable strategy to prevent β-cell demise in type 2 diabetes (Journal of Diabetes Research)
Preserved insulin secretory capacity and weight loss are the predominant predictors of glycemic control in patients with type 2 diabetes randomized to Roux-en-Y gastric bypass
Both weight loss and preserved β-cell function predominantly determine greatest glycemic benefit after RYGB (Diabetes)
