Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Inflammatory Bowel Disease II: Ulcerative Colitis

Inflammatory Bowel Disease II: Ulcerative Colitis

Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...

Epithelial Tissues and Their Functions

Epithelial Tissues and Their Functions

Epithelial tissues are large sheets of cells covering all of the surfaces of the body. These surfaces can be internal or external, for example, skin, airways, the digestive tract, the urinary system, and the reproductive system. Hollow organs and body cavities that do not connect to the body's exterior, including blood vessels and serous membranes, are lined by epithelial tissue known as the endothelium.
Epithelial tissues provide the body's first line of protection from physical, chemical, and...

Inflammatory Bowel Disease III: Crohn's Disease

Inflammatory 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...

Other Disorders of Digestive System

Other Disorders of Digestive System

The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

Amebiasis

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

Summary

This summary is machine-generated.

Eosinophilic gastrointestinal diseases (EGIDs) involve increased eosinophils in the gut. Research suggests these cells interact with the intestinal lining, potentially driving EGID inflammation and symptoms.

Area of Science:

Gastroenterology
Immunology
Cell Biology

Background:

Eosinophilic gastrointestinal diseases (EGIDs) present with diverse gastrointestinal symptoms.
Increased eosinophil counts in intestinal tissues are a hallmark of EGIDs.
The exact function of eosinophils in gastrointestinal dysfunction is not fully understood.

Purpose of the Study:

To review the evidence for interactions between the intestinal epithelium and eosinophils.
To explore the potential role of these interactions in the pathophysiology of EGIDs.
To discuss how epithelial-eosinophil crosstalk may contribute to gastrointestinal inflammatory diseases.

Main Methods:

Literature review of existing studies on eosinophils and the gastrointestinal epithelium.
Analysis of evidence from both gastrointestinal and other organ systems.
Synthesis of current understanding regarding epithelial-eosinophil interactions in inflammation.

Main Results:

Limited but suggestive evidence indicates interaction between intestinal epithelium and eosinophils.
Eosinophils are anatomically positioned close to the intestinal epithelium.
This proximity suggests a role in the development and progression of EGIDs.

Conclusions:

Epithelial-eosinophil interactions are likely involved in EGID pathogenesis.
Further research is needed to elucidate the precise mechanisms.
Understanding this crosstalk may lead to novel therapeutic strategies for EGIDs.
