Although bats are known to harbor MERS-CoV-related viruses, the role of bats in the evolutionary origin and pathway remains obscure. We identified a novel MERS-CoV-related betacoronavirus, Hp-BatCoV HKU25, from Chinese pipistrelle bats. While being closely related to MERS-CoV in most genome regions, its spike protein occupies a phylogenetic position between that of Ty-BatCoV HKU4 and Pi-BatCoV HKU5. Since Ty-BatCoV HKU4 but not Pi-BatCoV HKU5 can utilize MERS-CoV receptor, hDPP4, for cell entry, we tested the ability of Hp-BatCoV HKU25 to bind and utilize hDPP4...

Dipeptidyl peptidase 4 (DPP4), also known as CD26 is a type II transmembrane protein that is released from the cell membrane in a nonclassical secretory mechanism. This exopeptidase selectively degrades varieties of substrates including incretin hormones, growth factors, and cytokines. A significant detectable amount of DPP4 activity can be measured in plasma as well as in different tissues such as intestinal epithelium, vascular endothelium, lymphocytes, monocytes, kidney, liver, adipose, lung, thymus, spleen, prostate, etc...

The newer oral therapies for type 2 diabetes (T2DM); dipeptidyl peptidase-4 (DPP-4) inhibitors and sodium glucose cotransporter 2 (SGLT2) inhibitors have advantages over older agents. DPP-4 inhibitors are weight neutral, and have few adverse effects. SGLT2 inhibitors have additional benefits; weight loss, blood pressure reduction, cardiovascular risk reduction, and renoprotective effects. SGLT2 inhibitors, have increased risk of urogenital infections and possible risk of "euglycaemic" diabetic ketoacidosis...

BACKGROUND AND OBJECTIVE: Asthma pathogenesis is dependent on the balance between regulatory and effector T cells, which display differential expression of CD25 and CD26. Therefore, alteration of circulating levels of sCD25 and sCD26 during allergic asthma could be conditioned by leukocyte phenotype changes. Objectives: To analyse CD25 and CD26 expression on T lymphocytes and their soluble derivatives (sCD25, sCD26) during stable phases of moderate-severe allergic asthma. METHODS: Cross-sectional study with two adult cohorts of allergic asthmatics...

Middle East respiratory syndrome coronavirus (MERS-CoV) has been a highly threatening zoonotic pathogen since its outbreak in 2012. Similar to SARS-CoV, MERS-CoV belongs to the coronavirus family and can induce severe respiratory symptoms in humans, with an average case fatality rate of 35% according to the World Health Organization. Spike (S) protein of MERS-CoV is immunogenic and can induce neutralizing antibodies, thus is a potential major target for vaccine development. Here we constructed a chimeric virus based on the vesicular stomatitis virus (VSV) in which the G gene was replaced by MERS-CoV S gene (VSVΔG-MERS)...

Developing tumors continuously release nano-sized vesicles that represent circulating "fingerprints" of the tumor's identity.  In gastrointestinal stromal tumor (GIST), we have previously reported that these tumors release "oncosomes" carrying the constitutively activated tyrosine kinase (TK) receptor KIT.  Despite the clinical utility of TK inhibitors, such as imatinib mesylate (IM), recurrence and metastasis are clinical problems that urge the need to identify new tumor-derived molecules.  To this aim, we performed the first high quality proteomic study of GIST-derived exosomes (GDEs) and identified 1,060 proteins composing the core GDE proteome (cGDEp)...

Exposure to psychosocial stress is a risk factor for cardiovascular disease, including vascular aging and regeneration. Dipeptidyl peptidase-4 (DPP-4) exerts many physiological and pharmacological functions by regulating its extremely abundant substrates [e.g., glucagon-like peptide-1 (GLP-1), stromal cell-derived factor-1α/ C-X-C chemokine receptor type-4, etc.]. Over the past decade, emerging data revealed unexpected roles for DPP-4 and GLP-1 in intracellular signaling, oxidative stress production, lipid metabolism, cell apoptosis, immune activation, insulin resistance, and inflammation...

Therapeutic engineering of glucagon-like peptide-1 (GLP-1) has enabled development of new medicines to treat type 2 diabetes mellitus. These injectable analogues achieve robust glycemic control by increasing concentrations of 'GLP-1 equivalents' (∼50 pM). Similar levels of endogenous GLP-1 occur following gastric bypass surgery, and mechanistic studies indicate glucose lowering by these procedures is driven by GLP-1. Therefore, due to the remarkable signaling and secretory capacity of the GLP-1 system, we sought to discover mechanisms that raise GLP-1 pharmacologically...

T2DM is a complex disease underlined by multiple pathogenic defects responsible for the development and progression of hyperglycaemia. Each of these factors can now be tackled in a more targeted manner thanks to glucose-lowering drugs that have been made available in the past 2 to 3 decades. Recognition of the multiplicity of the mechanisms underlying hyperglycaemia calls for treatments that address more than 1 of these mechanisms, with more emphasis placed on the earlier use of combination therapies. Although chronic hyperglycaemia contributes to and amplifies cardiovascular risk, several trials have failed to show a marked effect from intensive glycaemic control...

Type 1 diabetes is a chronic organ-specific autoimmune disease in which selective destruction of insulin-producing β cells leads to impaired glucose metabolism and its attendant complications. IA2(5)P2-1, a potent immunogenic carrier which designed by our laboratory, can induce high titer specific antibodies when carry a B cell epitope, such as B cell epitopes of DPP4, xanthine oxidase, and Urate transporter protein. In this report, we describe a novel multi-epitope vaccine composing a peptide of DPP4, an anti-diabetic B epitope of Insulinoma antigen-2(IA-2) and a Th2 epitope (P2:IPALDSLTPANED) of P277 peptide in human heat shock protein 60 (HSP60)...

Prevention of the formation of advanced glycation end-products (AGEs) is a reliable approach to achieve control over hyperglycemia and the associated pathogenesis of diabetic vascular complications. In these terms, new synthetic approaches to 6-nitroazolo[1,5-a]pyrimidines have been developed on the basis of the promising antiglycation activity of their structural analogues, such as azolo[5,1-c][1,2,4]triazine-4(1H)-ones. A number of nitroazolopyrimidines were obtained by using nitration, chlorodeoxygenation, and amination reactions, and their antidiabetic properties were elucidated in vitro...

Middle East respiratory syndrome coronavirus (MERS-CoV) has caused human respiratory infections with a high case fatality rate since 2012. However, the mode of virus transmission is not well understood. The findings of epidemiological and virological studies prompted us to hypothesize that the human gastrointestinal tract could serve as an alternative route to acquire MERS-CoV infection. We demonstrated that human primary intestinal epithelial cells, small intestine explants, and intestinal organoids were highly susceptible to MERS-CoV and can sustain robust viral replication...

Sodium-glucose cotransporter 2 inhibitor (SGLT2-i) effects on cardiac ischemia/reperfusion (I/R) injury are unclear. Unlike SGLT2-i, dipeptidyl peptidase 4 inhibitors (DPP4-i) have shown effective cardioprotection in cardiac I/R injury. We aimed to investigate whether SGLT2-i reduces myocardial dysfunction and myocardial injury to a greater extent than DPP4-i in obese-insulin resistant rats with/without cardiac I/R injury. The high fat (HF) diet induced obese-insulin resistant rats were divided into 4 groups and received the following treatments for 28 days: vehicle (HFV); vildagliptin at a dosage of 3 mg/kg/day (HFVil); dapagliflozin at a dosage of 1 mg/kg/day (HFDa); and combination drugs (HFDaVil)...
