Type 1 diabetes is a progressive autoimmune disease characterized by the selective destruction of insulin-producing β-cells by CD8+ T cells. Although the mechanisms of antigen-specific β-cell killing are well established, the broader consequences of this targeted destruction on neighboring β-cells that escape direct T-cell receptor (TCR)–mediated attack remain poorly understood. Here, we developed a coculture […]

Obstructive sleep apnea (OSA) is a common condition strongly linked to increased cardiovascular risk and poor glycemic control. Little is known about OSA, cardiovascular risk, and glycemia in maturity-onset diabetes of the young (MODY), an inherited form of diabetes, which is different than both type 1 and type 2 diabetes. We assessed OSA, resting heart […]

Polygenic scores strongly predict type 1 diabetes risk, but most scores were developed in European-ancestry populations. In this study, we leveraged recent multiancestry genome-wide association studies to create a Type 1 Diabetes Multi-Ancestry Polygenic Score (T1D MAPS). We trained the score in the Mass General Brigham (MGB) Biobank (372 individuals with type 1 diabetes) and […]

Preclinical studies show that dietary or central administration of monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) can reduce food intake, enhance energy expenditure, and attenuate hypothalamic inflammation (HI), whereas saturated fatty acids (SFAs) promote weight gain, HI, and neuronal injury. However, whether hypothalamic exposure to different fatty acids similarly influences HI and body […]

There is significant evidence that acute stress, a challenge to an organism’s homeostasis, has dramatic effects on metabolic control. Acute stress impairs blood glucose control in people with both type 1 and type 2 diabetes. In addition, growing evidence suggests that metabolic responses to stress in people without diabetes may be a crucial determinant of health. […]

Gestational diabetes mellitus (GDM) is defined as hyperglycemia first identified during pregnancy and can lead to adverse maternal and neonatal outcomes. The molecular mechanisms leading to these outcomes are currently poorly understood. While transcriptomics of GDM placentas has been previously studied, the effect on precursor mRNA splicing remains largely unknown. This study explores the impact […]

Each month, the Diabetes editorial team chooses a single paper to be designated the Paper of the Month, which is then made available for free online and added to an exclusive collection (https://diabetesjournals.org/collection/1619/Diabetes-Paper-of-the-Month). Congratulations to the 2025 winners! Source link

Establishing the relevance of a genetic variant in the causality of a given disease is crucial. Clinical molecular geneticists use a variety of tools including mode of inheritance, segregation in the family, penetrance, and determination of the variant as loss of function (LOF) or gain of function (GOF). However, this approach to determining how a […]
