The cell-cell junctions of mammalian testes: I. The adhering junctions of the seminiferous epithelium represent special differentiation structures [PDF]

, 2014
The seminiferous tubules and the excurrent ducts of the mammalian testis are physiologically separated from the mesenchymal tissues and the blood and lymph system by a special structural barrier to paracellular translocations of molecules and particles ...

Targeting the GPX4–FUNDC1 Interaction with Magnesium Lithospermate B Attenuates Sepsis‐Associated Lung Injury

Advanced Science, EarlyView.
The diagram depicts the endothelial‐protective mechanism of magnesium lithospermate B (MLB) in sepsis‐associated lung injury. MLB binds GPX4 at Gly79, disrupts its interaction with FUNDC1, prevents mitophagy‐mediated GPX4 degradation, restores mitophagic flux, reduces ROS, and limits ferroptosis.

Loss of αT-catenin alters the hybrid adhering junctions in the heart and leads to dilated cardiomyopathy and ventricular arrhythmia following acute ischemia. [PDF]

, 2012
It is generally accepted that the intercalated disc (ICD) required for mechano-electrical coupling in the heart consists of three distinct junctional complexes: adherens junctions, desmosomes and gap junctions. However, recent morphological and molecular

Endothelial Cell‐Based Vascular Bandages for Blood–Brain Barrier Repair and Targeted siRNA Delivery

Advanced Science, EarlyView.
mECs restore blood–brain barrier function after cerebral ischemia–reperfusion by simultaneously targeting, supporting, and regulating the damaged vasculature. mECs home to injured cerebral vessels through interactions with highly expressed VLA‐4, reinforce endothelial integrity by forming new junctions, and, upon OGD‐SN treatment, acquire enhanced ...

Formin' adherens junctions

The Journal of Cell Biology, 2003
Epithelial cells zipper together thanks to linear actin cables—cables that assemble at newly formed adherens junctions to stabilize them, thereby counteracting retractive forces at sites of cell–cell contact. Now, Agnieszka Kobielak, Amalia Pasolli, and Elaine Fuchs (Rockefeller University, New York, NY) have found that formin-1 drives the actin ...

Cellular Identity Crisis: RD3 Loss Fuels Plasticity and Immune Silence in Progressive Neuroblastoma

Advanced Science, EarlyView.
Researchers discovered that therapy‐induced loss of RD3 protein in neuroblastoma triggers a dangerous shift: cancer cells become more stem‐like, invasive, and resistant to treatment while evading immune detection. RD3 loss suppresses antigen presentation and boosts immune checkpoints, creating an immune‐silent environment.

The epithelial integrity is preserved during particle exchange across the epithelium by macrophages and dendritic cells

European Respiratory Review, 2008
The epithelium of the human airway wall serves as structural and functional barrier against inhaled and deposited particulate antigen. Recently we have shown that human blood monocyte-derived dendritic cells (MDDC) and human blood monocytes derived ...

Murine MPDZ-linked hydrocephalus is caused by hyperpermeability of the choroid plexus. [PDF]

, 2019
Though congenital hydrocephalus is heritable, it has been linked only to eight genes, one of which is MPDZ Humans and mice that carry a truncated version of MPDZ incur severe hydrocephalus resulting in acute morbidity and lethality.

Dietary Baicalin Supplementation Can Enhance the Growth Performance of Weaned Piglets and Maintain the Intestinal Barrier Integrity

Animal Research and One Health, EarlyView.
This research innovatively illustrates baicalin’s multifaceted mechanisms in enhancing piglets’ intestinal health: modulating bile acid metabolism via probiotics, reinforcing tight junction proteins (ZO‐1/claudin), suppressing TLR4/NF‐κB‐mediated inflammation, whereas promoting growth and reducing diarrhea.

Microtubule-dependent balanced cell contraction and luminal-matrix modification accelerate epithelial tube fusion

Nature Communications, 2016
During tracheal tube fusion in Drosophila, a pair of tip cells form an adherens junction and then fuse their plasma membranes. Here the authors show that a balanced pulling force mediated by myosin and microtubules, as well as localized deposition of ...
