To elucidate the etiology of type 1 diabetes, the affected pancreas needs to be thoroughly characterized. Pancreatic innervation has been suggested to be involved in the pathology of the disease and a reduction of sympathetic innervation of the islets was recently reported. In the present study, we hypothesized that parasympathetic innervation would be altered in the type 1 diabetes pancreas. Human pancreatic specimens were obtained from a unique cohort of individuals with recent onset or long standing type 1 diabetes. Density of parasympathetic axons was assessed by immunofluorescence and morphometry. Our main finding was a reduced density of parasympathetic axons in the exocrine, but not endocrine compartment of the pancreas in individuals with recent onset type 1 diabetes. The reduced density of parasympathetic axons in the exocrine compartment could have functional implications, e.g. be related to the exocrine insufficiency reported in type 1 diabetes patients. Further studies are needed to understand whether reduced parasympathetic innervation is a cause or consequence of type 1 diabetes.

Immune Transcriptome of Cells Infected with Enterovirus Strains Obtained from Cases of Autoimmune Thyroid Disease

Anello Marcello Poma, Sarah Salehi Hammerstad, Angelo Genoni, Alessio Basolo, Knut Dahl-Jorgensen, Antonio Toniolo

Summary: Autoimmune thyroid disorders such as Hashimoto's thyroiditis and Graves' disease are thought to potentially have origins in enterovirus infections of thyroid cells. Research has shown that persistent enterovirus infection in thyroid tissue from AITD patients can suppress interferon and cytokine pathways while upregulating genes associated with immune responses. These findings suggest a potential benefit in targeting viral infections and inflammation in the early stages of AITD.

Summary: The Diabetes Virus Detection (DiViD) study collected pancreatic tissue, purified pancreatic islets, duodenal mucosa, serum, PBMCs, and stools from six adult patients with newly diagnosed type 1 diabetes. The study found enterovirus (EV) RNA in various tissues of these patients, indicating a potential persistent virus in the pancreatic islets of some patients.

Increased Expression of Viral Sensor MDA5 in Pancreatic Islets and in Hormone-Negative Endocrine Cells in Recent Onset Type 1 Diabetic Donors

Summary: The interaction between genetic and environmental factors determines the development of type 1 diabetes. Some viruses can infect and damage pancreatic beta cells, and MDA5 may play a role in the response of pancreatic islets to viral infections. In T1D donors, MDA5 expression is increased and may characterize dedifferentiated or newly forming islet cells.

Pancreas Whole Tissue Transcriptomics Highlights the Role of the Exocrine Pancreas in Patients With Recently Diagnosed Type 1 Diabetes

Summary: This study analyzed the whole-pancreas gene expression of recently diagnosed type 1 diabetes (T1D) patients and found that the expression of core acinar cell genes was higher in the patients compared to non-diabetic controls. Upregulation of immune and inflammation related genes was observed in the pancreatic islets of T1D patients, while downregulation of regenerating gene family (REG) genes was observed in the exocrine acinar cell dominated whole-pancreas samples. The study highlights the importance of studying both exocrine and endocrine compartments of the pancreas to better understand the molecular mechanisms of T1D.

Detection of Antiviral Tissue Responses and Increased Cell Stress in the Pancreatic Islets of Newly Diagnosed Type 1 Diabetes Patients: Results From the DiViD Study

Summary: The study reveals that newly diagnosed type 1 diabetes patients have enhanced gene expressions related to cellular stress and increased immunological activity in their islet cells compared to controls. Additionally, increased viral response proteins were observed in beta-cells of newly diagnosed type 1 diabetes patients, providing evidence for the hypothesis that enteroviral infection of islet beta-cells contributes to the pathogenesis of type 1 diabetes.

Summary: The incidence of type 1 diabetes in children under 18 years of age increases after COVID-19 infection. Decreased expression of PDE12 is associated with T1D development, while rare PDE12 SNPs may increase the risk of T1D.

Development of Type 1 Diabetes may occur through a Type 2 Diabetes mechanism

Knud Josefsen, Lars Krogvold, Ivan C. Gerling, Flemming Pociot, Knut Dahl-Jorgensen, Karsten Buschard

Summary: This study suggests that dormant beta cells in type 1 diabetes (T1D) exhibit secretion defects, fetal dedifferentiation, and desynchronization. Combining with previous evidence, it is proposed to treat individuals with ongoing T1D development prophylactically with type 2 diabetes (T2D) medicine and anti-inflammatory compounds to reactivate dormant beta cells and prevent autoimmune destruction. Further investigation into T2D mechanisms during T1D development is needed.

Summary: This study aimed to identify transcriptional changes associated with disease progression in patients with recent-onset type 1 diabetes. They found that genes and pathways related to innate immunity were downregulated during the first year after diagnosis. Associations between gene expression changes and ZnT8A autoantibody positivity were also observed. Additionally, changes in the expression of 16 genes were found to predict the decline in C-peptide at 24 months, and increased B cell levels and decreased neutrophil levels were associated with rapid progression, consistent with previous reports.

Histological and transcriptional characterization of the pancreatic acinar tissue in type 1 diabetes

Louise Granlund, Anders Hedin, Miriam Wahlhuetter, Peter Seiron, Olle Korsgren, Oskar Skog, Marcus Lundberg

Summary: This study showed that acinar nuclei density is preserved and no acinar atrophy is found in type 1 diabetes. The expression of digestive enzymes is evenly distributed, with occasional amylase-negative regions in formalin-fixed tissues. Transcriptional alterations in type 1 diabetes in the acinar tissue, independent of the distance from islets, were also identified. The enrichment of gene sets Myc Targets V2 and Estrogen Response Early may be linked to the increased incidence of pancreatic cancer in type 1 diabetes.

Disturbed eating, illness perceptions, and coping among adults with type 1 diabetes on intensified insulin treatment, and their associations with metabolic control

Line Wisting, Astrid Ro, Torild Skrivarhaug, Knut Dahl-Jorgensen, Oyvind Ro

Summary: This study found that among females with type 1 diabetes, illness perception personal control and coping strategy seeking emotional social support explained 23.2% of the variance in hemoglobin A1c, while among males, personal control remained significant and explained 13.9% of the variance. The associations between psychological aspects and hemoglobin A1c suggest that addressing these aspects clinically may help improve metabolic control and reduce the risk of complications.
