The present review tries to coordinate anatomical barriers and the biochemical and immunological events controlling and even preventing the entry of substances from the external environment into the extra- and intra-cellular space of the body. A selection of diseases with disturbance of the "barrier function" is included.

Background: C-type lectin (CTL) plays an important act in parasite adhesion, host's cell invasion and immune escape. Our previous studies showed that recombinant Trichinella spiralis C-type lectin (rTsCTL) mediated larval invasion of enteral mucosal epithelium. The aim of this study was to investigate protective immunity produced by vaccination with rTsCTL and its effect on gut epithelial barrier function in a mouse model.

To preserve barrier function, cell-cell junctions must dynamically remodel during cell shape changes. We have previously described a rapid tight junction repair pathway characterized by local, transient activation of RhoA, termed "Rho flares", which repair leaks in tight junctions via promoting local actomyosin-mediated junction remodeling. In this pathway, junction elongation is a mechanical trigger that initiates RhoA activation through an influx of intracellular calcium and recruitment of p115RhoGEF.

Exertional heat stroke (EHS) is a life-threatening condition characterized by hyperthermia and multi-organ dysfunction, often associated with intestinal barrier disruption. This study evaluated the protective effects of Huoxiang Zhengqi Dropping Pills (HXZQD) against EHS in a rat model. HXZQD was administered via oral gavage at low, medium, and high doses, followed by EHS induction through exercise under high-temperature and high-humidity conditions.

Background: Oxyberberine (OBB) is a naturally occurring isoquinoline alkaloid that is believed to possess various health-promoting properties, including anti-fungus, hepatoprotection, anti-inflammation, and anti-intestinal mucositis effects. Despite several studies reporting the health benefits of OBB in treating ulcerative colitis (UC), its specific mechanism of action has yet to be fully elucidated.
Purpose: This investigation is designed to explore the potential protective efficacy of OBB and the latent mechanism using an model of UC-like inflammatory intestinal cells.

Background: In the Kazakh community of Xinjiang, China, fermented camel milk has been traditionally used to manage diabetes. This study evaluates the effects of composite probiotics derived from fermented camel milk (CPCM) on metabolic disturbances in a rat model of Type 2 diabetes (T2DM).
Methods: T2DM was induced in Wistar rats using streptozotocin.
