    Determinants of Sustained Stabilization of Beta-Cell Function Following Short-Term Insulin Therapy in Type 2 Diabetes

    Independent predictors of sustained stabilization were the change in beta-cell function during induction, and changes in hepatic insulin resistance and alanine aminotransferase during maintenance.

    Platelet-Derived Lipids Promote Insulin Secretion of Pancreatic β Cells

    Investigators showed that factor(s) derived from β cells stimulated platelet activity and platelets selectively localized to the vascular endothelium of pancreatic islets.

    Heparanase 2 (Hpa2)- a New Player Essential for Pancreatic Acinar Cell Differentiation

    The lack of Hpa2 was associated with a marked decrease in the expression of key pancreatic transcription factors such as PTF1, GATA6, and Mist1.

    Glucose Controls Glucagon Secretion by Regulating Fatty Acid Oxidation in Pancreatic Alpha Cells

    The glucose dependent inhibition of glucagon secretion relies on pyruvate dehydrogenase and carnitine palmitoyl transferase 1a activity and lowering of mitochondrial fatty acid oxidation by increases in glucose.

    Abstract

    Verapamil Prevents Decline of IGF-1 in Subjects with T1D and Promotes Beta-Cell IGF-1 Signaling

    Researchers found that verapamil reduced beta-cell expression of IGF-binding protein 3 (IGFBP3), whereas IGFBP3 was increased in human islets exposed to type 1 diabetes-associated cytokines and diabetic NOD mouse islets.

    Abstract

    Reg Family Proteins Contribute to Inflammation and Pancreatic Stellate Cells Activation in Chronic Pancreatitis

    To investigate the role of Reg family proteins in chronic pancreatitis, scientists generated global knockout mice for regenerating genes (Reg) 1-3 using the CRISPR/Cas9 system.

    Schwann Cells Regulate Tumor Cells and Cancer-Associated Fibroblasts in the Pancreatic Ductal Adenocarcinoma Microenvironment

    In vitro and in vivo assays demonstrated that Schwann cells enhanced the proliferation and migration of PDAC cells via Midkine signaling, and promoted the switch of cancer-associated fibroblasts (CAFs) to basal-like and inflammatory CAFs via interleukin-1α.

    Targeting Leucine-Rich Repeat Serine/Threonine-Protein Kinase 2 Sensitizes Anti-PD-L1 Immunotherapy of Pancreatic Ductal Adenocarcinoma

    Proteomic analysis was performed to compare changes of Panc02 cell lines cultured with conditional medium and leucine rich repeat kinase 2 was identified as a differential gene.

    Simultaneous Establishment of Pancreatic Cancer Organoid and Cancer-Associated Fibroblast Using a Single-Pass Endoscopic Ultrasound-Guided Fine Needle Biopsy Specimen

    Various clinicopathologic factors, including the tumor size, tumor location, clinical stage, histologic subtype, and tumor differentiation, did not influence the patient-derived organoid establishment.

    Immune Vulnerabilities of Mutant KRAS in Pancreatic Cancer

    T cells engineered with mutant (m)KRAS-specific T cell receptors have already shown early clinical promise, and next-generation mKRAS vaccines are being studied. As this emerging field rapidly develops, scientists suggest that a significant component in ‘drugging KRAS’ may be immunological.

    Abstract

    Reversing Pancreatic β-Cell Dedifferentiation in the Treatment of Type 2 Diabetes

    The authors focus on the causes and implications of β-cell failure, as well as its potential reversibility as a type 2 diabetes treatment.
