Mucosal Tolerance a Barrier? Perspectives on Mucosal Vaccines: Is

Mucosal Immunity and Vaccines

These mucosal surfaces, while located inside the body, are actually a physical barrier between the outside and the sterile interior cavity of the body known as the “systemic” environment. Critical nutrients, oxygen and other molecules are constantly taken up across these mucosal barriers; however, another important function of the mucous is to keep invading pathogens out [15]. Daily these mucou...

Biliary Mucosal Barrier and Microbiome

BACKGROUND The biliary system is in continuous contact with the complex microbiota of the intestine. Microbial products have recently been proposed as potential triggers for biliary diseases. METHODS The aim of this review is to provide a summary of the current knowledge regarding the role of the biliary and intestinal microbiome in biliary inflammatory diseases. RESULTS Previously, it was ...

The mucosal barrier at a glance.

Mucosal barriers separate self from non-self and are essential for life. These barriers, which are the first line of defense against external pathogens, are formed by epithelial cells and the substances they secrete. Rather than an absolute barrier, epithelia at mucosal surfaces must allow selective paracellular flux that discriminates between solutes and water while preventing the passage of b...

GASTRIC MUCOSAL PROTECTION Peripheral mechanisms of gastric mucosal protection: mediators, receptors Gastric mucosal barrier to acid

Gastric mucosal integrity can be influenced both by peripheral and central mechanisms. In the last decades the peripheral mechanisms of gastric mucosal defense have been intensively studied, and many details have been clarified. Some of these results have served as a basis for the development of new strategies, therapeutic targets in the treatment of gastric mucosal lesions. On the other hand, ...
