Summary
Melatonin shows potential anti-inflammatory effects in inflammatory bowel disease (IBD) models by modulating immune cells and pathways. Its dual role in autophagy may explain varied outcomes in human studies, necessitating further research.
Area of Science:
- Gastroenterology
- Immunology
- Endocrinology
Background:
- The intestinal epithelium is crucial for nutrient absorption and immune system regulation.
- Inflammatory bowel disease (IBD) pathogenesis is increasingly understood, with biologics offering new treatments.
- Current IBD therapies have limitations, with many patients not responding or losing response over time.
Purpose of the Study:
- To review new data on melatonin's role in IBD.
- To discuss the molecular mechanisms underlying melatonin's effects in IBD.
- To explore the connection between melatonin, autophagy, and IBD.
Main Methods:
- Review of experimental and human studies on melatonin and IBD.
- Analysis of melatonin's immunoregulatory and anti-inflammatory mechanisms.
- Investigation of melatonin's impact on autophagy pathways in IBD.
Main Results:
- Melatonin demonstrates anti-inflammatory effects in experimental colitis models.
- Mechanisms include immune cell modulation, reduced pro-inflammatory mediators, and antioxidant activity.
- Melatonin's effects on autophagy may be dual, potentially explaining varied clinical outcomes.
Conclusions:
- Melatonin exhibits promising therapeutic potential for IBD through various molecular pathways.
- The complex relationship between melatonin and autophagy warrants further investigation for targeted IBD therapies.
- More human studies are needed to clarify melatonin's efficacy and safety in IBD patients.

01:27Autophagy
5.1K
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

01:36Delivery Pathways to the Lysosome
7.6K
Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.

69
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...

01:22Cellular Injury V: Apoptosis and Autophagy
121
Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...

01:18Autophagic Cell Death
3.3K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

01:19Management of Insomnia
788
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
