Ion transport across epithelial tissues plays a fundamental role in physiological processes, including nutrient absorption, waste excretion, and cellular homeostasis. To understand the underlying mechanisms governing ion movement, researchers employ specialized techniques such as the Ussing chamber, which facilitates the study of both active and passive transport. This article delves into the principles of ion…
The Ussing chamber is a classic experimental apparatus used to study the transport properties and barrier functions of epithelial tissues—surfaces that line organs such as the intestines, lungs, and kidneys. By mounting a section of live tissue between two chambers, researchers can precisely control the environment on both the “mucosal” (luminal) side and the “serosal”…
Discover how carvacrol combats DSS-induced colitis by downregulating NF-κB/MAPK signaling, boosting TGR5 expression, and reinforcing gut barrier integrity for potential therapeutic benefits – L-Cysteine protects intestinal integrity, attenuates intestinal inflammation and oxidant stress, and modulates NF-κB and Nrf2 pathways in weaned piglets after LPS challenge.

Hydrogen Sulfide Triggering Secretion This study explores how hydrogen sulfide (H₂S) triggers secretion in the intestines, focusing on the mechanisms and pathways involved. H₂S, a gasotransmitter, is known for its role in regulating various physiological processes and its potential therapeutic uses. Researchers investigated the effects of an H₂S donor compound, NaHS, on guinea-pig and human…
In the study “Neural influences on human intestinal epithelium in vitro,” researchers actively investigated how multiple neural factors importantly affect ion transport across human intestinal epithelial tissues. To achieve this goal, they actively used the EasyMount Ussing Chamber system from Physiologic Instruments, which effectively enabled them to mount isolated intestinal tissue samples between two chambers,…
Researchers in the study titled “Effects of Food Components That Activate TRPA1 Receptors on Mucosal Ion Transport in the Mouse Intestine” used the EasyMount Ussing Chamber system from Physiologic Instruments. They sought to examine multiple dietary components and their effects on ion transport across the intestinal mucosa. The team used this apparatus to mount isolated…
In the study “Modulation of the Respiratory Epithelium Physiology by Flavonoids—Insights from 16HBEσ Cell Model,” researchers actively examined how specific flavonoids—kaempferol, luteolin, as well as naringenin—effect the physiology of human bronchial epithelial cells. Researchers sought to understand how these compounds importantly influence multiple aspects of cell behavior. They concentrated on cell metabolic activity, proliferation, epithelial…
