REVIEW
Roland Zell
Picornaviruses are small, nonenveloped, icosahedral RNA viruses with positive-strand polarity. Although the vast majority of picornavirus infections remain asymptomatic, many picornaviruses are important human and animal pathogens and cause diseases that affect the central nervous system, the respiratory and gastrointestinal tracts, heart, liver, pancreas, skin and eye. A stunning increase in the number of newly identified picornaviruses in the past decade has shown that picornaviruses are globally distributed and infect vertebrates of all classes...

Bariatric surgery is currently the most effective treatment of obesity, which has spurred an interest in developing pharmaceutical mimetics. It is thought that the marked body weight-lowering effects of bariatric surgery involve stimulated secretion of appetite-regulating gut hormones, including glucagon-like peptide 1. We here report that intestinal expression of secretin is markedly upregulated in a rat model of Roux-en-Y gastric bypass, suggesting an additional role of secretin in the beneficial metabolic effects of Roux-en-Y gastric bypass...

Post-transplantation lympho-proliferative disorder (PTLD) pathogenesis is related to EBV infection. Mismatch with the donor (EBV D+/R-) is the main risk factor for both early PTLD (< 1 year post transplantation) and late (> 1 year). In these at-risk patients, the role of antiviral prophylaxis for preventing PTLD remains controversial. We analysed the impact of antiviral drugs given to prevent CMV disease in a mono-centric retrospective cohort of 73 adult kidney or kidney-pancreas EBV seronegative recipients, transplanted between 01/01/2000 and 01/01/2016...

Recent studies have provided evidence for a regulatory role of GLI-similar (GLIS) transcription factors in reprogramming, maintenance and differentiation of several stem and progenitor cell populations. GLIS1, in conjunction with several other reprogramming factors, was shown to markedly increase the efficiency of generating induced pluripotent stem cells (iPSC) from somatic cells. GLIS2 has been reported to contribute to the maintenance of the pluripotent state in hPSCs. In addition, GLIS2 has a function in regulating self-renewal of hematopoietic progenitors and megakaryocytic differentiation...

The paper investigated the antihyperglycemic and antihyperlipidemic efficacy and antioxidant capacity of Chimonanthus nitens Oliv. leaf extract (COE) in combination of high-glucose-fat diet-fed and streptozotocin-induced diabetic model mice. Various physiological indexes in diabetic model mice were well improved especially by oral administration of high dose of COE; the results were listed as follows. Fast blood glucose (FBG) level and serum triglyceride (TC), total cholesterol (TG), low-density lipoprotein cholesterol (LDLC), and malondialdehyde (MDA) as well as MDA in liver were significantly reduced; fasting serum insulin (FINS) and insulin sensitivity index (ISI) were both increased; high-density lipoprotein cholesterol (HDLC) in serum was significantly increased; total antioxidant capacity (T-AOC), activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) in serum and liver were apparently enhanced; liver coefficient (LC), liver transaminase, and alkaline phosphatase (ALP) were decreased...

To interrogate the alternative fates of pancreas and liver in the earliest stages of human organogenesis, we developed laser capture, RNA amplification, and computational analysis of deep sequencing. Pancreas-enriched gene expression was less conserved between human and mouse than for liver. The dorsal pancreatic bud was enriched for components of Notch, Wnt, BMP, and FGF signaling, almost all genes known to cause pancreatic agenesis or hypoplasia, and over 30 unexplored transcription factors. SOX9 and RORA were imputed as key regulators in pancreas compared with EP300, HNF4A, and FOXA family members in liver...

BACKGROUND: Solid pseudo papillary neoplasm (SPN) of the pancreas which predominantly affects young women is a relatively indolent entity with favorable prognosis. Resection through minimal access approach helps to achieve better short term benefits. The aim of this study is to describe our experience in laparoscopic management of this disease. METHODS: A retrospective review of our prospectively maintained database revealed that 17 patients with SPN were managed with surgical resection between March 2009 and October 2016...

Inflammatory bowel disease is thought to arise from inappropriate inflammation to gut bacteria, yet mechanisms preventing these responses remain elusive. In this issue of Cell, Nanjundappa et al. report that Bacteroides share an epitope with a pancreas-specific peptide that induces protective CD8+ T cells, identifying molecular mimicry as a mechanism to enforce tolerance in the gut.

Amin Ardestani, Kathrin Maedler
Hippo signaling is an evolutionarily conserved pathway that critically regulates development and homeostasis of various tissues in response to a wide range of extracellular and intracellular signals. As an emerging significant player in many diseases, the Hippo pathway is also involved in the pathophysiology of diabetes on the level of the pancreatic islets. Multiple lines of evidence uncover the importance of Hippo signaling in pancreas development as well as in the regulation of β-cell survival, proliferation and regeneration...

GPR40 agonists are effective antidiabetic agents believed to lower glucose through direct effects on the beta cell to increase glucose stimulated insulin secretion. However, not all GPR40 agonists are the same. Partial agonists lower glucose through direct effects on the pancreas, whereas GPR40 AgoPAMs may incorporate additional therapeutic effects through increases in insulinotrophic incretins secreted by the gut. Here we describe how GPR40 AgoPAMs stimulate both insulin and incretin secretion in vivo over time in diabetic GK rats...

Irreversible electroporation (IRE) is increasingly used for the ablation of unresectable locally advanced pancreatic adenocarcinoma. Unlike other ablation technologies that cannot be safely used around critical vasculature or ducts for risk of thermal damage, IRE uses high-voltage pulses to disrupt cellular membranes. This causes cell death by apoptosis and inflammation. IRE has been deployed by both open and percutaneous approaches. Generator parameters are the same for both approaches, and settings are pancreas specific...

Type-1 Diabetes (T1D) is a devastating autoimmune disorder which results in the destruction of beta cells within the pancreas. A promising treatment strategy for T1D is the replacement of the lost beta cell mass through implantation of immune-isolated microencapsulated islets referred to as the bioartificial pancreas. The goal of this approach is to restore blood glucose regulation and prevent the long-term comorbidities of T1D without the need for immunosuppressants. A major requirement in the quest to achieve this goal is to address the oxygen needs of islet cells...

BACKGROUND: Although soybean meal (SBM) is excellent source of protein in diets for poultry, it is sometimes inaccessible, costly and fluctuates in supply. The SBM can partially be replaced by full-fat SBM, but the meals prepared from raw full-fat soybean contain antinutritional factors. To avoid the risk of antinutritional factors, heat treatment is always advisable, but either excessive or under heating the soybean could negatively affect the quality. However, the potential for further improvement of SBM by supplementing with microbial enzymes has been suggested by many researchers...

Taurine is a conditionally essential amino acid present in the body in free form. Mammalian taurine is synthesized in the pancreas via the cysteine sulfinic acid pathway. Anti-oxidation and anti-inflammation are two main properties through which it exerts its therapeutic effects. Many studies have shown its excellent therapeutic potential against diabetes mellitus and related complications like diabetic neuropathy, retinopathy, nephropathy, hematological dysfunctions, reproductive dysfunctions, liver and pancreas related complications etc...

Dysregulated potassium (K(+)) channels have previously been shown to promote the development and progression of many types of cancers. Meanwhile, K(+) channels are particularly important in regulating the endocrine and exocrine functions of pancreas. However, the expression pattern and prognostic significance of K(+) channels in pancreatic ductal adenocarcinoma (PDAC) remain unknown. In this study, by screening a GEO dataset containing 36 microdissected PDAC and matching normal pancreatic tissue samples, four differentially expressed K(+) channels (KCNJ5, KCNJ16, KCNN4 and KCNK1) were identified in PDAC...

Literature data suggest that inflammatory cells such as mast cells (MCs) are involved in angiogenesis. MCs can stimulate angiogenesis by releasing of well identified pro-angiogenic cytokines stored in their cytoplasm. In particular, MCs can release tryptase, a potent in vivo and in vitro pro-angiogenic factor. Nevertheless, few data are available concerning the role of MCs positive to tryptase in primary pancreatic cancer angiogenesis. This study analyzed the correlation between mast cells positive to c-Kit receptor (c-Kit(+) MCs), the density of MCs expressing tryptase (MCD-T) and microvascular density (MVD) in primary tumor tissue from patients affected by pancreatic ductal adenocarcinoma (PDAC)...

Immunotherapy has shown a tremendous success in treating cancer. Unfortunately, this success is frequently associated with severe autoimmune pathology. In this study, we used the transgenic RIP-gp mouse model to assess the antitumor therapeutic benefit of peptide vaccination while evaluating the possible associated autoimmune pathology. We report that palmitoylated gp33-41 peptide and poly-IC adjuvant vaccine (BiVax) generated ∼ 5-10 % of antigen specific T cell responses in wild type and supposedly immune tolerant RIP-gp mice...
