- AIMS/HYPOTHESIS: The aim of this study was to ascertain whether treatment of GAD65 autoantibody (GADA)-positive diabetic patients with alum-formulated recombinant GAD65 (GAD-alum) is safe and does not compromise beta cell function. METHODS: This Phase 2, placebo-controlled, dose-escalation clinical trial, which was randomized through a central office, was performed in 47 GADA-positive type 2 diabetic patients, who received subcutaneous injections of GAD-alum (4 [n = 9], 20 [n = 8], 100 [n = 9] or 500 [n = 8] mug) or placebo (n = 13) at weeks 1 and 4 of the trial. Participants and caregivers were blinded to group assignments. The primary outcome was safety as assessed by neurological tests, medications and beta cell function evaluated over 5 years, representing the end of the trial. RESULTS: No severe study-related adverse events occurred during the 5 year follow-up. None of the dose groups was associated with an increased risk of starting insulin treatment compared with the placebo group. The use of oral hypoglycaemic agents did not differ between the dose groups. After 5 years, fasting C-peptide levels declined in the placebo group (-0.24; 95% CI -0.41 to -0.07 log(10) nmol/l; p = 0.01) and the 500 microg dose group (-0.37; 95% CI -0.57 to -0.17 log(10) nmol/l; p = 0.003), but not in the 4 microg (-0.10; 95% CI -0.28 to 0.07 log(10) nmol/l; p = 0.20), 20 microg (0.04; 95% CI -0.12 to 0.19 log(10) nmol/l; p = 0.58) and 100 microg (0.00; 95% CI -0.20 to -0.20 log(10) nmol/l; p = 0.98) dose groups. CONCLUSIONS/INTERPRETATION: The primary outcome of safety was achieved, since no severe study-related adverse events occurred. TRIAL REGISTRATION: Because the study was initiated before 1 July 2005, the protocol was not registered in a registry. FUNDING: This trial was funded by the National Institutes of Health (grant numbers DK26190 and DK53004), the Swedish Research Council (grant number 72X-14064) and Diamyd Therapeutics (Stockholm, Sweden).

- Extracellular vesicles (EVs) are submicron-sized lipid envelopes that are produced and released from a parent cell and can be taken up by a recipient cell. EVs are capable of mediating cellular signalling by carrying nucleic acids, proteins, lipids and cellular metabolites between cells and organs. Metabolic dysfunction is associated with changes in plasma concentrations of EVs as well as alterations in their EV cargo. Since EVs can act as messengers between parent and recipient cells, they could be involved in cell-to-cell and organ-to-organ communication in metabolic diseases. Recent literature has shown that EVs are produced by cells within metabolic tissues, such as adipose tissue, pancreas, muscle and liver. These vesicles have therefore been proposed as a novel intercellular communication mode in systemic metabolic regulation. In this review, we will describe and discuss the current literature that investigates the role of adipose-derived EVs in the regulation of obesity-associated metabolic disease. We will particularly focus on the EV-dependent communication between adipocytes, the vasculature and immune cells in type 2 diabetes.

- In vivo imaging of the developing pancreas is challenging due to the inaccessibility of the tissue. To circumvent this, on embryonic day 10.5 (E10.5) we transplanted a mouse developing pancreatic bud into the anterior chamber of the eye (ACE) to determine whether the eye is a useful transplant site to support pancreas development. We transplanted an E10.5 dorsal pancreatic bud into the ACE of a syngeneic recipient mouse. Using a mouse insulin promoter-green fluorescent protein (MIP-GFP) mouse as the tissue donor, we non-invasively imaged the pancreatic bud as it develops at single beta cell resolution across time. The transplanted pancreatic bud rapidly engrafts and vascularises when transplanted into the ACE. The pancreatic progenitor cells differentiate into exocrine and endocrine cells, including cells expressing insulin, glucagon and somatostatin. The morphology of the transplanted pancreatic bud resembles that of the native developing pancreas. Beta cells within the transplanted pancreatic bud respond to glucose in a manner similar to that of native fetal beta cells and superior to that of in vitro developed beta cells. Unlike in vitro grown pancreatic explants, pancreatic tissue developing in the ACE is vascularised, providing the developing pancreatic tissue with a milieu resembling the native situation. Altogether, we show that the ACE is able to support growth, differentiation and function of a developing pancreatic bud across time in vivo.
