Tight junctions at the blood brain barrier: physiological architecture and disease-associated dysregulation. [PDF]

open access: yes, 2012
International audienceABSTRACT: The Blood--brain barrier (BBB), present at the level of the endothelium of cerebral blood vessels, selectively restricts the blood-to-brain paracellular diffusion of compounds; it is mandatory for cerebral homeostasis and ...

Bacterial Extracellular Vesicles in the Pathogenesis and Treatment of Liver Diseases

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
Liver diseases are a major global health challenge, with current treatments inadequate. This review highlights the role of bacterial extracellular vesicles in liver inflammation, fibrosis, and metabolism. We also explore these from commensals and probiotics, their protective effects, and discuss research challenges and future therapeutic potential ...

Inflammatory and Immunological Basis of Periodontal Diseases

open access: yesJournal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

Porphyromonas gingivalis GroEL accelerates abdominal aortic aneurysm formation by matrix metalloproteinase‐2 SUMOylation in vascular smooth muscle cells: A novel finding for the activation of MMP‐2

open access: yesMolecular Oral Microbiology, EarlyView.
Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.

Optimising exercise intensity for gut health: Effect on microbiota composition, barrier integrity and inflammation in male Wistar rats

open access: yesExperimental Physiology, EarlyView.
Abstract Exercise influences gut microbiota composition and intestinal permeability, but the optimal intensity for maintaining gut health remains unclear. This study investigates the effects of different exercise intensities on abundance of some gut microbiota, epithelial barrier integrity and inflammatory markers.

Wnt/beta-catenin signaling controls development of the blood–brain barrier [PDF]

open access: yes, 2009
The blood–brain barrier (BBB) is confined to the endothelium of brain capillaries and is indispensable for fluid homeostasis and neuronal function. In this study, we show that endothelial Wnt/beta-catenin (beta-cat) signaling regulates induction and ...

Immunomodulatory effects of cathelicidin in the gut–brain axis: A novel link between mucosal immunity and neuroinflammation

open access: yesExperimental Physiology, EarlyView.
Abstract Cathelicidins are evolutionarily conserved host defence peptides known for their dual antimicrobial and immunomodulatory functions. Among them, LL‐37 in humans and CRAMP in rodents have emerged as crucial regulators of both mucosal immunity and CNS inflammation.

Tight junction proteins in glial tumors development and progression

open access: yesFrontiers in Cellular Neuroscience
Tight junctions form a paracellular barrier in epithelial and endothelial cells, and they regulate the diffusion of fluids, molecules, and the penetration of cells across tissue compartments.

Milk Fat Globule Membrane Supplementation Attenuates Cognitive Impairment in APP/PS1 Mice via Suppressing Neuroinflammation in a Gut Microbiota‐Mediated Serum Resolvin D1/Anandamide Manner

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
MFGM modulated gut microbiota accompanied by the increased serum RVD1 and AEA levels, which subsequently regulated the miRNA profile. This modulation alleviated neuroinflammation via suppressing the NLRP3 inflammasome signaling and microglial activation, thereby attenuating AD‐related cognitive impairment both in vivo and in vitro.

Progesterone is neuroprotective by inhibiting cerebral edema after ischemia

open access: yesNeural Regeneration Research, 2015
Ischemic edema can alter the structure and permeability of the blood-brain barrier. Recent studies have reported that progesterone reduces cerebral edema after cerebral ischemia.
