Abstract
Autoimmune diabetes arises spontaneously in Non-Obese Diabetic (NOD) mice, and the pathophysiology of this disease shares many similarities with human type 1 diabetes. Since its generation in 1980, the NOD mouse, derived from the Cataract Shinogi strain, has represented the gold standard of spontaneous disease models, allowing to investigate autoimmune diabetes disease progression and susceptibility traits, as well as to test a wide array of potential treatments and therapies. Beyond autoimmune diabetes, NOD mice also exhibit polyautoimmunity, presenting with a low incidence of autoimmune thyroiditis and Sjögren’s syndrome. Genetic manipulation of the NOD strain has led to the generation of new mouse models facilitating the study of these and other autoimmune pathologies. For instance, following deletion of specific genes or via insertion of resistance alleles at genetic loci, NOD mice can become fully resistant to autoimmune diabetes; yet the newly generated diabetes-resistant NOD strains often show a high incidence of other autoimmune diseases. This suggests that the NOD genetic background is highly autoimmune-prone and that genetic manipulations can shift the autoimmune response from the pancreas to other organs. Overall, multiple NOD variant strains have become invaluable tools for understanding the pathophysiology of and for dissecting the genetic susceptibility of organ-specific autoimmune diseases. An interesting commonality to all autoimmune diseases developing in variant strains of the NOD mice is the presence of autoantibodies. This review will present the NOD mouse as a model for studying autoimmune diseases beyond autoimmune diabetes.

[PMID: 32572592 PMCID: PMC7310027 DOI: 10.1186/s13550-020-00657-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Accepted: 06/09/2020] [Indexed: 02/07/2023] Open
Abstract
Purpose Soluble epoxide hydrolase (sEH) is a promising candidate positron emission tomography (PET) imaging biomarker altered in various disorders, including vascular cognitive impairment (VCI), Alzheimer’s disease (AD), Parkinson’s disease (PD), stroke, and depression, known to regulate levels of epoxyeicosatrienoic acids (EETs) and play an important role in neurovascular coupling. [18F]FNDP, a PET radiotracer for imaging sEH, was evaluated through quantitative PET imaging in the baboon brain, radiometabolite analysis, and radiation dosimetry estimate. Methods Baboon [18F]FNDP dynamic PET studies were performed at baseline and with blocking doses of the selective sEH inhibitor AR-9281 to evaluate sEH binding specificity. Radiometabolites of [18F]FNDP in mice and baboons were measured by high-performance liquid chromatography. Regional brain distribution volume (VT) of [18F]FNDP was computed from PET using radiometabolite-corrected arterial input functions. Full body distribution of [18F]FNDP was studied in CD-1 mice, and the human effective dose was estimated using OLINDA/EXM software. Results [18F]FNDP exhibited high and rapid brain uptake in baboons. AR-9281 blocked [18F]FNDP uptake dose-dependently with a baseline VT of 10.9 ± 2.4 mL/mL and a high-dose blocking VT of 1.0 ± 0.09 mL/mL, indicating substantial binding specificity (91.70 ± 1.74%). The VND was estimated as 0.865 ± 0.066 mL/mL. The estimated occupancy values of AR-9281 were 99.2 ± 1.1% for 1 mg/kg, 88.6 ± 1.3% for 0.1 mg/kg, and 33.8 ± 3.8% for 0.02 mg/kg. Murine biodistribution of [18F]FNDP enabled an effective dose estimate for humans (0.032 mSv/MBq). [18F]FNDP forms hydrophilic radiometabolites in murine and non-human primate plasma. However, only minute amounts of the radiometabolites entered the animal brain (< 2% in mice). Conclusions [18F]FNDP is a highly sEH-specific radiotracer that is suitable for quantitative PET imaging in the baboon brain. [18F]FNDP holds promise for translation to human subjects.

Abstract
As a result of less than optimal outcomes the use of islet allografts as a standard insulin replacement therapy is limited to adults with a history of extreme glucose dysregulation and hypoglycemia unawareness. In this study, we examined the use of prophylactic immunotherapy to prevent islet allograft rejection in the absence of antirejection drugs. Our protocol to achieve allograft acceptance used a negative vaccination strategy that is comprised of apoptotic donor cells delivered in Incomplete Freund's Adjuvant (IFA) 1 week prior to islet transplantation. The goal of this new protocol is to elicit hyporesponsiveness to alloantigen prior to islet transplantation. First, we examined our protocol without islet allograft transplants and determined that the negative vaccination was not globally immunosuppressive or immunostimulatory. Islet allograft experiments using fully MHC-mismatched islet donors and recipients demonstrated that the negative vaccination strategy induced long-term islet allograft acceptance. Upon rechallenge with alloantigen, the negative vaccination protocol successfully achieved hyporesponsiveness. In addition, the microenvironment at the site of the tolerant allograft revealed a decrease in proinflammatory mediators (IFN-γ, TNF-α) and an increase in the anti-inflammatory mediator IL-10, as well as increased expression of the master regulator of T-regulatory cells, FOXP3. Our data suggest that pretreating allograft recipients with apoptotic donor alloantigen delivered in IFA induced long-term islet allograft acceptance and glycemic control by introducing alloantigen to the recipient immune system in a nonimmunostimulatory manner prior to transplant.

Abstract
Previous studies by our group, using an experimental autoimmune thyroiditis (EAT) model in Strain 13 inbred guinea pigs, resulted in T cell-mediated delayed hypersensitivity; however, autoantibodies proved not to be cytotoxic to thyroid epithelial cells in the presence or absence of complement proteins. Albeit, T cell-mediated lymphocyte cytotoxicity began to diminish sharply concomitantly with increasing titers of circulating autoantibodies, indicating a skewing of the self-reactive response and amelioration of the EAT. Furthermore, immunization of guinea pigs with thyroglobulin in incomplete Freund's adjuvant (IFA) generated a high titer of antithyroglobulin antibodies and proved to inhibit thyroiditis. These observations indicated that the shift in the immune response from Th1 to Th2 and the production of antibodies were likely responsible for ameliorating EAT. Based upon these results, we extrapolated our studies to design a multivalent vaccine, which shows promise in preventing/reversing T1D in NOD mice. A small pilot study was conducted in which a total of 34 mice, 20 non-immunized controls and 14 immunized with syngeneic islet lysate, were monitored for mean day to diabetes for a total of 28 weeks. Immunization of NOD animals with syngeneic islet lysates resulted in a significant delay in diabetes onset (P < 0.001) as compared to non-immunized controls. To further assess the vaccine's efficacy, robustness, and delay of disease, a large-scale experiment was conducted and monitored for 32 weeks using 106 mice, 64 non-immunized controls and 42 immunized with syngeneic islet lysate. At the end of the study, 90% of the non-immunized group developed diabetes, while less than 25% of the immunized group became diabetic (P < 0.0001). The protective effect, as a result of vaccination, correlated with an increase in the levels of IL-10 and IL-4 cytokines as well as a skewing to Th2-dependent isotype antibodies in serum. Strikingly, adoptive transfer of spleen cells from immunized animals into NOD.scid recipients provided protection against transfer of diabetes by diabetogenic spleen cells. The results of this study provide evidence that vaccination with islet lysate leads to a Th2-dependent skewing of the immune response to islet beta cells as a possible mechanism of protection. This strategy may be implemented as a possible vaccination protocol for arresting and/or preventing T1D in patients.

Abstract
The purpose of this study is to assess the potential of dendritic cells transfected with PD-L1 recombinant adenovirus induces CD8+ T cell suppression and kidney allograft tolerance. To prove it, DCs transfected with PD-L1 recombinant adenovirus (DC/Ad-PD-L1) were transferred into the MHC-mismatched rat kidney transplants. After kidney transplantation, the mixed lymphocyte reaction (MLR) assay and kidney function were analyzed. The results demonstrated that after administration of DC/Ad-PD-L1, the proliferation, cytokines secretion and activation marker expression of CD8+ T cells were suppressed. In addition, DC/Ad-PD-L1 could improve kidney function and survival of transplants. The findings suggested that DC/Ad-PD-L1 could induce CD8+ T cell tolerance and lead to kidney allograft tolerance, which provided a promising finding for clinical application.

Abstract
Type 1 diabetes (T1D) is a chronic autoimmune disease in which destruction or damaging of the beta-cells in the islets of Langerhans results in insulin deficiency and hyperglycemia. We only know for sure that autoimmunity is the predominant effector mechanism of T1D, but may not be its primary cause. T1D precipitates in genetically susceptible individuals, very likely as a result of an environmental trigger. Current genetic data point towards the following genes as susceptibility genes: HLA, insulin, PTPN22, IL2Ra, and CTLA4. Epidemiological and other studies suggest a triggering role for enteroviruses, while other microorganisms might provide protection. Efficacious prevention of T1D will require detection of the earliest events in the process. So far, autoantibodies are most widely used as serum biomarker, but T-cell readouts and metabolome studies might strengthen and bring forward diagnosis. Current preventive clinical trials mostly focus on environmental triggers. Therapeutic trials test the efficacy of antigen-specific and antigen-nonspecific immune interventions, but also include restoration of the affected beta-cell mass by islet transplantation, neogenesis and regeneration, and combinations thereof. In this comprehensive review, we explain the genetic, environmental, and immunological data underlying the prevention and intervention strategies to constrain T1D.

Abstract
In 1922, Leonard Thompson received the first injections of insulin prepared from the pancreas of canine test subjects. From pancreatectomized dogs to the more recent development of animal models that spontaneously develop autoimmune syndromes, animal models have played a meaningful role in furthering diabetes research. Of these animals, the nonobese diabetic (NOD) mouse is the most widely used for research in type 1 diabetes (T1D) because the NOD shares several genetic and immunologic traits with the human form of the disease. In this article, the authors discuss the similarities and differences in NOD and human T1D and the potential role of NOD mice in future preclinical studies, aiming to provide a better understanding of the genetic and immune defects that lead to T1D.

Abstract
The cJun N-terminal kinase 1 (JNK1) is implicated in diet-induced obesity. Indeed, germline ablation of the murine Jnk1 gene prevents diet-induced obesity. Here we demonstrate that selective deficiency of JNK1 in the murine nervous system is sufficient to suppress diet-induced obesity. The failure to increase body mass is mediated, in part, by increased energy expenditure that is associated with activation of the hypothalamic-pituitary-thyroid axis. Disruption of thyroid hormone function prevents the effects of nervous system JNK1 deficiency on body mass. These data demonstrate that the hypothalamic-pituitary-thyroid axis represents an important target of metabolic signaling by JNK1.

Abstract
Type 1 diabetes (T1D) is an organ-specific autoimmune disease featured by destruction of the insulin producing beta-cells of the pancreas by autoreactive T-lymphocytes. Putative environmental triggers conspire with a constellation of genetic elements scattered throughout the genome to elicit a multifactorial autoimmune response involving virtually every cell type of the immune system against pancreatic beta-cells. Recent highly powered genome-wide association studies have confirmed and identified fifteen chromosomal regions harboring several candidate T1D-associated gene loci. Here, we summarize what we know about the genetics of T1D with an emphasis on the contributions of mouse Il2 and human IL2RA polymorphisms and the IL-2-IL-2R pathway to autoimmunity and, more specifically, Treg development and function.
