NKX2.2 is a transcription factor that regulates pancreatic islet β-cell identity and function; however, cofactor proteins that modulate the functional activity of NKX2.2 in β-cells are relatively unexplored. An unbiased proteomics screen identified chromodomain helicase DNA-binding protein 4 (CHD4) as an NKX2.2 interacting partner. CHD4 is a nucleosome remodeler that directs the appropriate differentiation, maturation […]

Glucose-dependent insulinotropic polypeptide (GIP[1–42]) increases glucagon levels in the presence of normal-to-low plasma glucose concentrations in individuals with type 1 diabetes (T1D), suggesting its potential use as a safeguard against hypoglycemia. We investigated the dose-dependent effects of exogenous full-length GIP[1–42] and its truncated variant GIP[1–30]NH2 on glucagon concentrations during insulin-induced hypoglycemia in individuals with T1D. […]

Female protection against cardiometabolic disease wanes after menopause, concomitant with a transition toward the male-like pattern of visceral adiposity. Since recruitment of adipose progenitor cells (APCs) to support adipose expansion is depot-specific and thought to maintain metabolic homeostasis, sex differences in the capacity for APC differentiation were explored as a mechanism underlying female cardiometabolic protection. […]

Diabetic retinopathy (DR), a major complication of diabetes that causes blindness, is characterized by hyperglycemia-induced vascular dysfunction of incompletely defined mechanisms. Our study demonstrated glycolytic pathway activation in a DR rat model, which led to lactate accumulation and elevated pan lysine lactylation. Reduced lactate levels ameliorate vascular dysfunction. Global lactylome analysis of rat retinal tissues […]

We conducted a cross-sectional study to explore the interplay between β-cell function and peripheral insulin resistance in latent autoimmune diabetes in adults (LADA) compared with type 2 diabetes. Thirty-one people with LADA were matched for sex, BMI, and disease duration with 31 people with type 2 diabetes. Insulin resistance was estimated using established surrogate indexes, […]

Active Charcot neuroarthropathy (CN) remains difficult to predict. This hypothesis-generating article proposes a deliberately restricted, testable model in which a clinically meaningful fall in HbA1c may temporally coincide with active CN in a subset of people with diabetes, established neuropathy, and a vulnerable foot. The signal is based on a sequence of observations—an initial case […]

Diabetes is a major risk factor for severe periodontitis. This is partly due to impaired wound healing associated with concomitant failure to resolve inflammation and chronic infection. Studies from the Joslin Medalist Cohort, people with >50 years of type 1 diabetes, have reported that protective factors exist to delay the onset of severe retinopathy, nephropathy, […]
