Resumen
El entorno intestinal varía significativamente de arriba a abajo y dentro de sus capas de tejido. Estos nichos intestinales distintos albergan compartimentos especializados del sistema inmunológico adaptados a sus funciones específicas.
Área de la Ciencia:
- Gastroenterología
- Inmunología
- Microbiología
Sus antecedentes:
- El entorno intestinal exhibe una variación significativa a lo largo de su eje proximal a distal.
- Las funciones específicas del tejido y los contenidos luminales crean microambientes distintos dentro del intestino.
Objetivo del estudio:
- Para resaltar los compartimentos inmunes especializados presentes en diferentes nichos intestinales.
- Para subrayar la relación entre el medio intestinal y la especialización inmune.
Principales métodos:
- Revisión de la literatura existente sobre inmunología y microbiología intestinales.
- Análisis de las variaciones espaciales y funcionales dentro del tracto intestinal.
Principales resultados:
- El medio intestinal es heterogéneo, difiere en su composición y función a lo largo de su longitud y profundidad.
- Distintas poblaciones y estructuras de células inmunes están asociadas con regiones intestinales específicas (nichos).
Conclusiones:
- El intestino alberga compartimentos inmunes altamente especializados adaptados a las condiciones locales únicas.
- Comprender estos sistemas inmunológicos específicos de nicho es crucial para comprender la salud y la enfermedad intestinales.

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

6.4K
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...

A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

The gastrointestinal tract, responsible for the digestion and absorption of nutrients, is safeguarded by the intestinal barrier, which consists of secretory, physical, and immune components. At the forefront is the secretory barrier, composed of essential elements such as mucus, gut microbiota, and defense proteins. They collaborate to break down food particles, facilitate nutrient absorption, and maintain optimal gut health. These secretory components ensure the smooth functioning of the...
