Summary
The circadian clock regulates daily rhythms in immunity and digestion. Its disruption is linked to inflammatory bowel diseases (IBD), suggesting clock regulators are key to IBD inflammation.
Area of Science:
- Gastroenterology
- Immunology
- Chronobiology
Background:
- Inflammatory bowel diseases (IBD) are characterized by chronic immune activation and inflammation in the digestive tract.
- Immune system function and gastrointestinal processes display significant diurnal variations.
- These daily rhythms are orchestrated by the body's internal circadian clock.
Purpose of the Study:
- To investigate the potential role of the circadian clock in the pathogenesis of inflammatory bowel diseases.
- To explore the connection between circadian rhythm disruption and IBD-related inflammation.
Main Methods:
- This study reviews existing literature on circadian biology and inflammatory bowel diseases.
- It analyzes the molecular mechanisms linking circadian regulators to immune responses in the gut.
Main Results:
- Disruption of the circadian clock is increasingly associated with inflammatory conditions.
- Evidence suggests that circadian regulators influence immune cell activity and gut barrier function, both critical in IBD.
Conclusions:
- Circadian clock regulators are implicated as pivotal factors in the inflammatory processes underlying IBD.
- Targeting circadian pathways may offer novel therapeutic strategies for managing inflammatory bowel diseases.

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

4.0K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

01:17Chronic Bowel Disorders: Introduction
386
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

01:17Irritable Bowel Syndrome I: Introduction
246
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
