The DiViD-project collects biological material from patients with newly-diagnosed T1D in the age 18-40 years. The material includes pancreatic tissue, intestinal tissue, blood, urine, stool and throat-swab. If possible lymph-nodes are also collected. The material is biobanked and then investigated by several other members of the PEVNET to highlight the inflammatory process (insulitis) seen in patient with T1D, with a special focus on examining regarding the presence of viruses. The amount of material, especially the pancreatic and intestinal tissue and the lymph nodes, are very limited, and has to be treated with caution.

The team coordinated from Peninsula Medical School includes Professor Noel Morgan & Dr Sarah Richardson with collaborators Professor Alan Foulis (Glasgow) and Professor Adrian Bone (Brighton). The group has long-standing expertise in the isolation and functional characterization of pancreatic beta-cells. It has well established methods for study of the regulation of cell viability, cell cycle progression, proliferation and insulin secretion. The group also has considerable expertise in the application of immunohistochemistry, confocal and fluorescence microscopy to study of pancreatic immunopathology.
Professor Foulis contributes a critical resource (and expertise) for the present project, comprising a collection of over 70 autopsy pancreases of young people who died of type 1 diabetes shortly after clinical presentation. This represents the largest such collection worldwide. In these pancreases there is often active destruction of insulin secreting beta cells and the processes involved can therefore be studied in detail by examination of pancreatic sections. This resource (together with tissue samples from a wide range of controls) are being utilized to investigate the prevalence and consequences of enteroviral infection in human islets and to study the pattern of anti-viral responses and their relationship to islet autoimmunity in type 1 diabetes.
Partner is the leader of the WP3, Detection of viruses
Group’s role include:
Characterisation of the inflammatory infiltrate and expression of chemokines and their receptors in the inflamed islets of human patients with recent-onset type 1 diabetes
Definition of the anti-viral pathways activated during enteroviral infection of human islet cells.
Identification of the enteroviral serotypes present in human pancreas in type 1 diabetes by the use of serotype-specific antisera and methodologies to identify viral RNA sequences.
Analysis of beta cell proliferation in vivo in type 1 diabetic pancreases, and assessment of the factors which may promote beta cell division using cell biological techniques in vitro

Measuring T cell immune responses in individuals has been a main focus for our group. A major challenge within the field has been developing sensitive assays with high specificity for assessing rare autoreactive T cell responses. Development of highly sensitive ELISpot assays which allow qualitative assessment of responsive T cells, and tetramer technology permitting parallel examination of CD8 T cells bearing antigen specific TCR, have been major foci of our developmental work in the field of immune cell monitoring.
Another key aspect of our work in type 1 diabetes (T1D) has been the analysis of peptide epitopes presented by MHC class I molecules from β-cell antigens. CD8 T cells provide the cytotoxic end-stage in T1D through their direct contribution to destruction of β-cells. Irrefutable evidence for the importance of epitopes can be ascertained through assessment of peptide-specific CD8 T cell responses to human β-cells and other relevant targets. Thus we have expertise in isolation and characterization of peptide-specific CD8 T cells and in the analysis of their cytotoxic potential using relevant human targets.
Group goals within PEVNET
The association between enterovirus (EV) and T1D is now well founded, but there has been little research on the adaptive cellular arm of the immune response to EV. Our group’s goal within PEVNET will be to identify EV epitopes, and use ELISpot techniques to initially identify immunodominant peptide responses. Identification of immunodominant CD8 T cell peptides will allow us to investigate corresponding cells within T1D patients and controls using tetramers loaded with EV peptide. Techniques will also be implemented to isolate EV-specific CD8 T cells, and observe their interaction with human β-cells.
Investigating responses of patients and controls using these technologies will provide new tools for testing the strength and mechanism of EV association with T1D. CD8 T cell clones specific for these peptides can be used to further analyse whether there is direct cytotoxicity of EV infected or uninfected β-cells. In conjunction, we can examine the within the pancreas of EV-specific CD8 T cells by in situ tetramer staining.

A major research focus in Flodström-Tullberg’s laboratory is the etiopathogenesis of type 1 diabetes. More specifically, the interactions between infectious agents, the host immune system and the pancreatic beta cells are studied. Other research interests include cystic fibrosis related diabetes.
The group has strong expertise in innate immunity with a special interest in antiviral defense mechanisms. The group also has detailed knowledge on the etiopathogenesis of type 1 diabetes, experimental animal models for type 1 diabetes, as well as the generation of so-called humanized mouse models. Established techniques include in vitro and in vivo infection models, multicolor flow cytometry, immunohistochemistry, confocal microscopy, Real-Time PCR, Westernblot analysis, ELISA, transfection, RNA interference, virus titration (plaque assay and flow cytometry-based methods), islet isolation, islet transplantation, transgenic and knock-out animals.
Partner is the leader of the WP5, Innate immune system
The aims of WP5 are to characterize the innate immune response to enterovirus infections and to determine whether individuals with an increased genetic risk for type 1 diabetes development have an altered response to enteroviruses. A special focus is on the ifih1 gene, which harbors several non-synonymous SNPs associated with altered risk for diabetes development. The Flodström-Tullberg group will mainly work on these aims but also contribute to the work in WP4 (Persistent infection) and WP8 (Virus induced changes in islet cell cultures).

Vactech Ltd was founded to commercialize the research findings and subsequent IPR originating from academic research. One of the main products in the pipeline is an entero-virus-based vaccine to prevent Type 1 Diabetes. Vactech works in the early phase of the product-oriented development cycle in focused fields of application.
Traditional vaccines contain either killed or attenuated viruses. A more modern approach embraces the concept of Virus Like Particles, VLP. VLP-based vaccines deliver important advantages over traditional vaccines since they provide stronger immunostimulation than denatured virus particles or soluble viral proteins. In addition, they are often effective in eliciting both T- and B-cell immune responses while traditional vaccines induce mainly B-cell responses.
Partner has major role in WP10, Therapies and diagnostics for virus-induced inflammatory diseases, in collaboration with partner 13
Partner’s role is to develop and product the VLPs as therapies and diagnostics for virus-induced inflammatory diseases.
