Patients with EPE had a statistically significantly higher median Charlson comorbidity index and prevalence of renal disease (p = 0.01), compared to the 3GCSE control group. This study implies that EPE bacteremia can trigger production of IgG antibodies targeting ESBL. Further investigations are required to determine the functional role of anti-ESBL antibodies against EPE bacteremia.

Numerous studies have shown that Glucagon like peptide-1 (GLP-1) treatment can protect β cell function, but the exact mechanism remains unclear. We hypothesized that GLP-1 may protect β cell function via its action on insulin signaling pathway. Mice were fed with high fat diet (HFD, 20weeks) in the presence or absence of GLP-1 receptor agonist (exenatide) treatment. The islet structure was demonstrated by HE staining. Immunofluorescence antibodies targeting insulin and glucagon were used to illustrate α and β cell distribution. The insulin and glucagon abundance was measured by ELISA using pancreatic homogenates. The molecules involved in insulin signaling pathway (IRc, IRS1, IRS2, mTOR) in islet were examined with immunohistochemistry and immunoblotting. The effect of IRS1 silencing on mTOR and apoptosis were examined on NIT cells(β cell line)with immunoblotting and flow cytometry. HE and immunofluorescence staining demonstrated that the normal structure of islet was deformed in HFD mice but preserved by exenatide. Insulin and glucagon contents were increased in islet and blood stream of HFD mice (HFD vs
