Summary
Coeliac disease in children shows increased endocrine cells, particularly secretin cells. Further research is needed to understand if these cells overproduce or store secretin hormone.
Area of Science:
- Gastroenterology
- Endocrinology
- Cell Biology
Background:
- Coeliac disease is an autoimmune disorder affecting the small intestine.
- Endocrine cells in the jejunum play a role in nutrient sensing and hormone release.
- Altered endocrine cell populations have been observed in various gastrointestinal conditions.
Purpose of the Study:
- To investigate the morphology and distribution of jejunal endocrine cells in children with coeliac disease.
- To specifically examine the secretin (S) cells in coeliac patients.
- To explore potential alterations in secretin cell function in coeliac disease.
Main Methods:
- Immunofluorescence staining for secretin (anti-secretin).
- Cytochemical analysis of jejunal biopsies.
- Ultrastructural examination of jejunal tissue.
- Comparison between 16 children with coeliac disease and 17 controls.
Main Results:
- Generalized hyperplasia of endocrine cells was observed in 11 out of 16 coeliac children.
- A specific increase in secretin (S) cells was noted in these patients.
- Control group with suspected malabsorption but normal jejunal morphology showed no such changes.
Conclusions:
- Children with coeliac disease exhibit an increased number of jejunal endocrine cells, particularly secretin cells.
- The observed hyperplasia suggests a potential role for secretin in the pathophysiology of coeliac disease.
- Further studies involving adult coeliacs and serum secretin assays are warranted to elucidate the functional status of these S cells (abnormal storage vs. excess production).

01:05Insulin Secretory Vesicles
Insulin secretory vesicles release insulin to stimulate blood glucose uptake and regulate carbohydrate metabolism. When the blood glucose levels increase, glucose enters the pancreatic β-islet cells through glucose transporters. Once inside, glucose is metabolized through glycolysis, the citric acid cycle, and the electron transport chain, producing ATP. This increase in ATP concentration closes ATP-sensitive potassium channels, leading to depolarization of the membrane and the opening of...
01:23Renewal of Intestinal Stem Cells
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the goblet,...
00:55Microvilli
Microvilli are tiny finger-like projections found on the surface of certain cells. Their purpose is to increase the surface area of the cell's apical surface, resulting in more effective absorption or secretion of substances.
These microvilli are predominantly present in cells lining the small intestine, kidney tubules, and certain cells in the respiratory and reproductive systems. By significantly expanding the surface area of the cell membrane, microvilli enhance the cell's capacity to...

01:16Cells and Secretions of the Pancreas
The pancreas, a vital organ within the abdominal cavity, plays dual roles in the digestive and endocrine systems, collaborating with exocrine and endocrine cells to maintain optimal digestion and blood sugar levels.
Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
Concurrently, the dispersed clusters of endocrine cells throughout the...

01:25Hormones Secreted by the Stomach
Enteroendocrine cells, accounting for only 1% of stomach epithelial cells, play a significant role in digestion and are classified by their digestive hormone secretions.
Each of these hormones secreted by different enteroendocrine cells plays a unique role in digestion. Here are a few examples:

01:27Histology of the Small Intestine
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
