- Microbiología Microbiología.
Sus antecedentes:
- La inmunidad mucosal y la patogénesis de la enfermedad inflamatoria intestinal (EII) son áreas de investigación activa.
- La homeostasis intestinal se basa en complejas redes celulares que regulan la tolerancia inmune y la inflamación.
- Las interacciones huésped-microbios son cruciales para la salud intestinal.
Objetivo del estudio:
- Revisar los avances recientes en la comprensión de la inmunidad de la mucosa y la patogénesis de la EII.
- Para resaltar el papel de los programas celulares en la homeostasis intestinal.
- Para enfatizar el impacto de las predisposiciones genéticas y los factores ambientales en la salud intestinal.
Principales métodos:
- Revisión de la literatura científica más reciente.
- Análisis de los programas celulares involucrados en la homeostasis intestinal.
- Examen de estudios genéticos y modelos de ratón de EII.
Principales resultados:
- La homeostasis intestinal incluye diversas redes intracelulares e intercelulares.

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

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...
01:20Inflammatory Bowel Disease IV: Clinical Manifestations
Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The disease course is marked...
