TMEM16A Ca2+-activated Cl- channel inhibition ameliorates acute pancreatitis via the IP3R/Ca2+/NFκB/IL-6 signaling pathway

This study identifies a novel mechanism underlying the pathogenesis of AP by which IL-6 promotes TMEM16A expression via IL-6R/STAT3 signaling activation, and TMEM16A overexpression increases IL-6 secretion via IP3R/Ca2+/NFκB signaling activation in pancreatic acinar cells. TMEM16A inhibition may be a new potential strategy for treating AP.Graphical abstractA positive activation loop between TMEM16A and the IP3R/ Ca2+/NFκB/IL-6 pathway is important for Ca2+ elevation, NFκB activation and IL-6 release, and thus cooperatively promotes the pathogenesis of AP.

Conclusion: DW-MRI is a reliable noninvasive technique to differentiate sterile and infected pancreatic collections. ADC values from the periphery of the collection can predict infected pancreatic collections at an early stage. DW-MRI should not be considered as a substitute for aspiration cytology in patients with septic symptoms and absent diffusion restriction on MRI.

The interest in pancreatic stellate cells (PSCs) has been steadily growing over the past two decades due mainly to the central role these cells have in the desmoplastic reaction associated with diseases of the pancreas, such as pancreatitis or pancreatic cancer. In recent years, the scientific community has devoted substantial efforts to understanding the signaling pathways that govern PSC activation and interactions with neoplastic cells. This mini review aims to summarize some very recent findings on signaling in PSCs and highlight their impact to the field.

Chronic pancreatitis, a known risk factor for the development of pancreatic ductal adenocarcinoma (PDA), is a serious, widespread medical condition characterized by inflammation, fibrosis, and acinar to ductal metaplasia (ADM). ADM is a cell type transdifferentiation event where pancreatic acinar cells become ductal-like under conditions of injury or oncogenic mutation. Here, we show that chronic pancreatitis and ADM in genetically wild type mice results in the formation of a significant population of chemosensory tuft cells. Transcriptomic analyses of pancreatitis tuft cells identify expression of inflammatory mediators, ...

Pancreatic damage, in the form of pancreatitis, intestinal bacteria and glucose imbalance could be interrelated. The aim of this study was to investigate the breath hydrogen (H 2 ) and methane (CH 4 ), which can indicate small intestinal bacterial overgrowth (SIBO) status, and assess the link between SIBO and glucose tolerance in patients with acute pancreatitis (AP). This prospective study enrolled 75 patients who were admitted for AP. A glucose breath test (GBT) which detects breath hydrogen H 2 and CH 4 for SIBO with an oral glucose tolerance test (OGTT) for 120 min was simultaneously performed to determine SIBO a...

ConclusionOur data provided strong evidence for the participation of MIF in the pathogenesis of AP and subsequent inflammatory response. The genetic ablation of MIF or its inhibition with pharmacological agents significantly ameliorated the severity of AP.

AbstractObjectivesAcute pancreatitis (AP) is an inimical disorder associated with overall mortality rates between 10 ‐15%. It is a disorder of the exocrine pancreas which is characterized by local and systemic inflammatory responses primarily driven by oxidative stress and death of pancreatic acinar cells. The severity of AP ranges from mild pancreatic edema with complete recuperative possibilities to serious sy stemic inflammatory response resulting in peripancreatic/pancreatic necrosis, multiple organ failure, and death.Key findingsWe have retrieved the potential alternative approaches that are developed lately for eff...

We report a case of acute pancreatitis that occurred just after an elective screening colonoscopy; this is a rare event with very few reported cases. A healthy, asymptomatic male underwent screening colonoscopy at our center and developed abdominal pain and emesis after the procedure. An abdominal X-ray ruled out perforation but laboratory tests revealed elevated levels of amylase and lipase. The patient had no etiological risk factors for pancreatitis. The presumed mechanism of pancreatitis in this case is mechanical and pressure trauma from excessive insufflation, external abdominal pressure, and repeated withdrawal of t...

Blunt abdominal trauma is the major cause of abdominal injury in children. Pancreatic trauma, although infrequent, can be associated with major mortality and morbidity including hemorrhage, abscesses, fistulae, pancreatic leaks and pancreatitis [1].
