Resumen
Los investigadores descubrieron diversos microbios en el tejido adiposo mesentérico (MAT), desafiando las suposiciones anteriores. Estas bacterias intestinales contribuyen a la "grasa rampante" característica de la enfermedad de Crohn.
Área de la Ciencia:
- Microbiología
- Gastroenterología
- Inmunología
Sus antecedentes:
- La microbiota intestinal juega un papel crucial en la salud gastrointestinal.
- El tejido adiposo mesentérico (MAT) rodea el tracto gastrointestinal y su papel en el alojamiento de microbios no se comprende bien.
Objetivo del estudio:
- Investigar la diversidad microbiana dentro del tejido adiposo mesentérico (MAT).
- Para entender la contribución de estos microbios a la patogénesis de la enfermedad de Crohn, específicamente "la grasa que se arrastra".
Principales métodos:
- Análisis microbiano de muestras de tejido adiposo mesentérico.
- Identificación de las especies bacterianas y sus adaptaciones metabólicas.
Principales resultados:
- Se identificó una diversidad no apreciada previamente de microbios viables en el MAT.
- La evidencia sugiere que estos microbios están mal localizados desde la microbiota intestinal.
- Estas bacterias están metabólicamente adaptadas al entorno MAT.
Conclusiones:
- El MAT alberga una comunidad microbiana diversa.
- Las bacterias intestinales mal localizadas y adaptadas en el MAT contribuyen a la "grasa rampante" observada en la enfermedad de Crohn.

01:23Anatomy of the Intestines
85.9K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

01:29Bacterial Flora of the Large Intestine
1.0K
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

01:50What is Monogastric Digestion?
74.4K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

01:24Lipid Absorption
2.1K
Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.

01:02Hypodermis
7.0K
The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...
