Subpopulations of mouse beta cells

ABSTRACT: Type 1 diabetes (T1D) is a chronic autoimmune disease that involves immune mediated destruction of β cells. How β cells respond to immune attack is unknown. We identified a population of β cells during the progression of T1D in non-obese diabetic (NOD) mice that survives immune attack. This population develops from normal β cells confronted with islet infiltrates. Pathways involving cell movement, growth and proliferation, immune responses, and cell death and survival are activated in these cells. There is reduced expression of β cell identity genes and diabetes antigens and increased immune inhibitory markers and stemness genes. This new subpopulation is resistant to killing when diabetes is precipitated with cyclosphosphamide. Human β cells show similar changes when cultured with immune cells. These changes may account for the chronicity of the disease and the long term survival of β cells in some patients.

Increased β-cell proliferation prior to immune-cell invasion prevents progression of type 1 diabetes

Project description:Type 1 diabetes (T1D) is characterized by pancreatic islet infiltration by autoreactive immune cells and a near-total loss of β-cells. Restoration of insulin-producing β-cells coupled with immunomodulation to suppress the autoimmune attack has emerged as a potential approach to counter T1D. Here we report that enhancing β-cell mass in female NOD mice early in life (prior to weaning) results in immunomodulation of T-cells, reduced islet infiltration and lower β-cell apoptosis, that together protect them from developing T1D. We observed that a model exhibiting β-cell hyperplasia on the NOD background (NOD-LIRKO) displayed altered β-cell antigens, and islet transplantation studies showed prolonged graft survival of NOD-LIRKO islets even upon exposure to diabetogenic splenocytes in vivo. Adoptive transfer of splenocytes from the NOD-LIRKOs prevented diabetes development in pre-diabetic NOD mice, while conversely, similar protective outcomes were obtained when NOD-LIRKO splenocytes were adoptively transferred after mixing them with diabetogenic NOD splenocytes in a dose-dependent manner. A significant increase in the splenic CD4+CD25+FoxP3+ regulatory T-cell (Treg) population in the NOD-LIRKO mice was observed to drive the protected phenotype since Treg depletion rendered NOD-LIRKO mice diabetic. The increase in Tregs coupled with a downregulation of key mediators of cellular function, upregulation of apoptosis and activation of TGF-β/SMAD3 signaling pathway in pathogenic T-cells favored reduced ability to kill β-cells. These data provide novel evidence that initiating β-cell proliferation, alone, prior to islet infiltration by immune cells alters the identity of β-cells, decreases pathologic self-reactivity of effector cells and increases Tregs to prevent progression of T1D.

Genetic predisposition for beta cell fragility underlies type 1 and type 2 diabetes

Project description:Type 1 and type 2 diabetes (T1D and T2D) share pathophysiological characteristics, yet mechanistic links have remained elusive. T1D results from autoimmune destruction of pancreatic beta cells, while beta cell failure in T2D is delayed and progressive. Here we find a new genetic component of diabetes susceptibility in T1D non-obese diabetic (NOD) mice, identifying immune-independent beta cell fragility. Genetic variation in Xrcc4 and Glis3 alter the response of NOD beta cells to unfolded protein stress, enhancing the apoptotic and senescent fates. The same transcriptional relationships were observed in human islets, demonstrating the role for beta cell fragility in genetic predisposition to diabetes.

Islet-Autonomous Inflammatory Signaling Propagates Autoimmunity and Promotes Diabetes in Nonobese Diabetic Mice

Project description:Type 1 diabetes (T1D) is an immune-mediated disease that leads to β cell dysfunction and death. However, the contribution of β cells in this process remains unclear. To understand how islet-derived pro-inflammatory signaling pathways contribute to diabetes pathogenesis, we generated inducible islet-specific Alox15 knockout mice on the NOD background. We report that islet-specific deletion of Alox15 induced a substantial increase of β-cell mass and decreased islet insulitis, and ultimately lead to a protection against spontaneous autoimmune diabetes in NOD mice. Single cell RNA-sequencing and mass spectrometry analysis revealed that islet-specific knockout of Alox15 leads to an increase of β cells expressing Pd-l1 and promotes an anti-inflammatory phenotype in myeloid cells and T cells inside the islets. Furthermore, islet- specific Alox15 deletion enhances the expansion of M2-like macrophages and regulatory T cells in the pancreatic islets and pancreatic lymph nodes. Together, these results lead to the conclusion that proinflammatory signals produced by β cells allows these cells to express immunoregulators that protects these cells of immune cell attack and promote β cell survival.

microRNA expression data from peripheral blood mononuclear cell in patients with type 1 diabetes compared with normal controls.

Project description:Type 1 diabetes mellitus (T1D) is a common autoimmune disease mediated by autoimmune attack against pancreatic b cells. It has been reported that dys-regulation of microRNAs (miRNAs) may contribute to the pathogenesis of autoimmune diseases, including T1D. This study sought to identify T1D associated miRNAs in the peripheral blood mononuclear cell (PBMC). Peripheral blood mononuclear of newly diagnosed type1 diabetes patients and normal controls were purified by LymphoprepTm gradient purification according to the manufacturerM-bM-^@M-^Ys instructions (Axis-Shield PoC AS, Oslo, Norway) for futher microarray analysis.

Differential gene expression in beta cells and non-beta cells from islets of NOD mice

Project description:Diabetes (T1D) is a disease in which the immune system destroys the insulin-producing beta cells. Recently, researchers have become interested in the role of the innate immune system in initiating this process. To further investigate this, we used RNA-seq to analyze sorted beta cells from non-diabetic and pre-diabetic female non-obese models of diabetes (NOD). These results shed light on the potential involvement of m6A mediators in the development of T1D, highlighting a promising avenue for future research.

microRNAs of thymocytes and of peripheral and pancreas-infiltrating T lymphocytes

Project description:As early as one month of age, nonobese diabetic (NOD) mice feature pancreatic infiltration of autoreactive T lymphocytes, which destruct insulin-producing beta cells, producing autoimmune diabetes mellitus (T1D) within eightmonths. Thus, we hypothesized that during the development of T1D, the transcriptional modulation of immune reactivity genes may occur as thymocytes mature into peripheral T lymphocytes. The transcriptome of thymocytes and peripheral CD3+ T lymphocytes from prediabetic or diabetic mice analyzed through microarray hybridizations identified the differentially expressed genes.

Assessing the role of microRNAs in post-transcriptional control of thymocytes and peripheral lymphocytes in NOD mice

Project description:As early as one month of age, non-obese diabetic (NOD) mice feature pancreatic infiltration of autoreactive T lymphocytes, which destruct insulin-producing beta cells, leading to autoimmune diabetes mellitus (T1D) within eight months. Thus, we hypothesized that during the development of T1D, the transcriptional modulation of immune reactivity genes, as well as, modulation of microRNAs (miRNAs) may occur during thymocytes mature into peripheral CD3+ T lymphocytes. Our aim is to analyze the transcriptional modulation of mRNA and microRNAs during development of thymocytes into peripheral CD3+ T lymphocytes in the context of the emergence of T1D.

Transcriptome profile of peripheral blood mononuclear cells in patients with type I diabetes and their first grade relatives

Project description:Type 1 Diabetes (T1D) is considered to be a Th1 autoimmune disease characterised by an absolute lack of insulin caused by an autoimmune destruction of the insulin producing pancreatic beta cells. Th1 lymphocytes are responsible for the infiltration of the islets of Langerhans and for the cytokine release that supports cytotoxic (Tc) lymphocytes to mediate destruction of the beta cells. The preclinical disease stage is characterized by the generation of the self-reactive lymphocytes that infiltrate the pancreas and selectively destroy the insulin-producing beta cells present in the islets. Other cellular immune mechanisms regarding immunoregulation and antigen presentation and processing are involved in T1D pathogenesis as well. Our aim was to identify genes involved in the corresponding signalling cascades, especially those which may serve as promising diagnostic tools for the identification of persons in the prediabetic phase of the disease. We addressed the question by analysing gene expression profiles of freshly isolated peripheral blood mononuclear cells in type 1 diabetes patients, their first degree relatives divided according to their autoantibody status, and healthy controls. 9 T1D-patients versus 10 first degree relatives versus 10 healthy controls
