Enfermedad celíaca: una reacción similar al injerto contra el huésped localizada en la pared del intestino delgado?
Lancet (London, England)
|April 11, 1981
Resumen
La enfermedad celíaca implica que el gluten forme una célula linfoide extraña en el intestino, lo que desencadena una reacción similar al injerto contra el huésped (GvH). Esta reacción puede explicar los síntomas graves y la potencial transformación linfomatosa en la enfermedad celíaca no tratada.
Área de la Ciencia:
- Inmunología Inmunología.
- Gastroenterología y Gastroenterología.
- Patología Patología Patología.
Sus antecedentes:
- La enfermedad celíaca es un trastorno autoinmune desencadenado por la ingestión de gluten.
- La interacción del gluten con las células inmunes intestinales es fundamental para su patogénesis.
- Los modelos existentes no explican completamente todas las manifestaciones clínicas de la enfermedad celíaca.
Objetivo del estudio:
- Proponer un nuevo mecanismo para la patogénesis de la enfermedad celíaca.
- Para explicar las reacciones inmunes sistémicas y locales observadas en la enfermedad celíaca.
- Para vincular la enfermedad celíaca a los modelos de enfermedad de injerto contra huésped (GvH).
Principales métodos:
- Desarrollo de modelos conceptuales basados en la literatura existente.
- Comparación de la patología de la enfermedad celíaca con la enfermedad GvH experimental.
- Análisis de las interacciones de las células inmunes en la pared intestinal.
Principales resultados:
- El gluten forma una célula linfoide extraña con los macrófagos / linfocitos intestinales.
- Esta célula inicia una reacción autónoma similar al injerto contra el huésped (GvH).
- La reacción está localizada en el intestino, lo que explica la caquexia y la atrofia linfoide como características crónicas de GvH.
- La enfermedad no tratada puede conducir a un linfoma similar al GvH experimental.
Conclusiones:
- La patogénesis de la enfermedad celíaca puede entenderse como una reacción crónica similar a la GvH.
- Este modelo proporciona una explicación unificada para diversos hallazgos clínicos y patológicos.
- Investigaciones adicionales sobre los mecanismos similares a la GvH podrían informar el tratamiento de la enfermedad celíaca.

01:23Renewal of Intestinal Stem Cells
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the goblet,...
01:17Chronic Bowel Disorders: Introduction
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...

01:30Inflammatory Bowel Disease II: Crohn's Disease
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.

01:26Inflammatory Bowel Disease I: Introduction
Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows “skip lesions” in which...
01:20Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
01:25Inflammatory Bowel Disease III: Crohn's Disease
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...
