The Colon

The colon serves as the habitat for trillions of microbes, which it must maintain, regulate, and sequester. This is managed by what is termed the mucosal barrier. The mucosal barrier separates the gut flora from the host tissues; regulates the absorption of water, electrolytes, minerals, and vitamins; and facilitates host–flora interactions. Colonic homeostasis depends on a complex interaction between the microflora and the mucosal epithelium, immune system, vasculature, stroma, and nervous…

Colon Cancer is Associated with Microbial Dysbiosis in Humans and Animals

Through new mechanisms in CRC pathophysiology including bacterial approach, the perspectives of screening, diagnostic and prognostic tests are discussed and microbiota may be considered as a platform of host and environment interactions with which to study CRCs.

Microbiota and pathogen 'pas de deux': setting up and breaking down barriers to intestinal infection.

This review focuses on the role of the intestinal microbiota in promoting resistance to infection by bacterial pathogens as well as how pathogens overcome this barrier and examines how microbiota-derived signaling molecules interfere with bacterial virulence.

Goblet cell LRRC26 regulates BK channel activation and protects against colitis in mice

It is shown in mouse colon that the Ca2+- and voltage-dependent BK-type K+ channel, specifically in association with the LRRC26 regulatory subunit, plays a critical role in normal GC function, protecting mice against chemically induced colitis.

In Vitro Luminal Measurements of Colon Electrical Impedance in Rabbits

Electrical Bio Impedance techniques can be a useful tool for the study of the colon, with measurements taken from the luminal side, and the results suggest that there are differences between the proximal and the distal portions of the Colon.

Microbiota, Epithelium, Inflammation, and TGF-β Signaling: An Intricate Interaction in Oncogenesis

The triangle relationship of microbiota dysbiosis, epithelial barrier dysfunction and dysregulated immune responses is discussed to elucidate the mechanisms by which microbiota induces carcinogenesis, especially highlighting the reciprocal crosstalk between transforming growth factor-β signaling and every side of the tumorigenic triangle.

MRI of the Colon in the Pharmaceutical Field: The Future before us

This article provides a comprehensive; contemporary review of the literature on luminal MRI of the colonic environment of the last 15 years with specific focus on colon physiological dimensions; motility; chyme and fluids; transit and luminal flow.

Intestinal Permeability and Drug Absorption: Predictive Experimental, Computational and In Vivo Approaches

Recent advancements in the overall investigation and in vivo prediction of drug absorption are discussed and the understanding of the complex and highly dynamic physiology of the region from the mid-jejunum to the sigmoid colon could be significantly improved.



Microbial modulation of innate defense: goblet cells and the intestinal mucus layer.

The present review summarizes the results of developmental, gnotobiotic, and in vitro studies that showed alterations in mucin gene expression, mucus composition, or mucus secretion in response to intestinal microbes or host-derived inflammatory mediators.

Recent advances in relation to irritable bowel syndrome, inflammatory bowel disease, and colon cancer are focused upon and the possibility that the therapeutic solution may reside within the microbiota will be addressed.

Intestinal epithelial cells in inflammatory bowel diseases.

The possible role of the epithelial barrier is reviewed and the role of IECs is described, which provides a physical barrier capable of controlling antigen traffic through the intestinal mucosa, in the pathogenesis of inflammatory bowel diseases.

Epithelial crosstalk at the microbiota–mucosal interface

These immune mechanisms depend heavily on IEC recognition of microbes and are consistent with several studies in knockout mice that demonstrate TLR signaling in the epithelium has a profoundly beneficial role in maintaining homeostasis.

The model of colonic secretion and absorption is updated, new issues of transporter activation are discussed, and some important new receptor pathways are identified that are important modulators of the secretory and absorptive functions of the colon.

Principles and clinical implications of the brain–gut–enteric microbiota axis

Enterochromaffin cells are important bidirectional transducers that regulate communication between the gut lumen and the nervous system, and may have an important role in pain and immune-response modulation, control of background emotions and other homeostatic functions.

Innate immune signaling in defense against intestinal microbes

How signaling pathways, effector molecules, and cell populations that are activated by microbial molecule recognition are involved in the maintenance of homeostatic levels of host defense and in the early response to acute enteric infection are discussed.

Immune adaptations that maintain homeostasis with the intestinal microbiota

The unique adaptations of the intestinal immune system that maintain homeostatic interactions with a diverse resident microbiota are discussed.
