Summary
Triggering receptor expressed on myeloid cells-1 (TREM-1) exacerbates intestinal barrier dysfunction in severe acute pancreatitis (SAP). Blocking TREM-1 may reduce pancreatitis-associated intestinal damage and improve outcomes.
Area of Science:
- Immunology
- Gastroenterology
- Pathophysiology
Background:
- Severe acute pancreatitis (SAP) can lead to intestinal barrier dysfunction (IBD), increasing disease severity and mortality.
- The protein triggering receptor expressed on myeloid cells-1 (TREM-1) is implicated in innate immunity and inflammation.
Purpose of the Study:
- To investigate the role of TREM-1 in the pathophysiology of intestinal barrier dysfunction in SAP.
- To evaluate the effect of TREM-1 pathway modulation on pancreatitis-associated IBD in a rat model.
Main Methods:
- Experimentally induced SAP in a rat model.
- Quantification of serum TREM-1 and membrane-bound TREM-1 in intestinal and pancreatic tissues.
- Administration of LP17 to block the TREM-1 pathway.
Main Results:
- TREM-1 levels were assessed in serum and tissues of SAP rats.
- LP17 treatment demonstrated potential to suppress pancreatitis-associated IBD.
- TREM-1 pathway blockade may ameliorate intestinal mucosa barrier damage.
Conclusions:
- TREM-1 plays a significant role in the development of intestinal barrier dysfunction during SAP.
- Modulating the TREM-1 pathway, for instance with LP17, offers a potential therapeutic strategy for SAP-associated IBD.

01:21Chronic Pancreatitis II: Pathophysiology
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
01:21Acute Pancreatitis II: Pathophysiology
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
01:24Chronic Pancreatitis I: Introduction
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

01:25Chronic Pancreatitis I: Introduction
Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
01:27Acute Pancreatitis I: Introduction
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
