The interstitial cells of Cajal of the equine gastrointestinal tract: what we know so far.

The research article is an in-depth review on the interstitial cells of Cajal in the equine gastrointestinal tract, focusing on their function, involvement in intestinal motility disorders, and their role in diseases like large intestinal obstructive colic and grass sickness.

Understanding Interstitial Cells of Cajal

• The article starts by examining the interstitial cells of Cajal (ICCs), which are key in controlling bowel function.
• These cells play a crucial role as pacemakers and mediators of certain types of neurotransmission in the gastrointestinal tract. In simple terms, they help control the rhythm and speed of digestion.

Relation to Gastrointestinal Disorders

• The research highlights that these interstitial cells of Cajal can contribute to gastrointestinal motility disorders, conditions where the muscles of the digestive system don’t work as they should, leading to problems in digestion.
• They may be directly or indirectly involved in the development of gastrointestinal diseases which disrupt intestinal motility.

Implications in Equine Diseases

• The review also brings attention to the involvement of ICCs in certain equine diseases, namely large intestinal obstructive colic and grass sickness (also known as equine dysautonomia).
• Large intestinal obstructive colic is a severe form of abdominal pain, and grass sickness is a disease that affects the nervous system of horses, causing damage in the gut’s nerves.

The Role of ICCs in Equine Gastrointestinal Tract

• The concluding part of the article investigates the function of ICCs in the equine gastrointestinal tract, specifically how they manipulate the intestines’ motility patterns.
• The study also summarizes the current understanding of these cells’ importance in the equine gastrointestinal tract from a scientific perspective.
