A new terahertz technique reveals nanometer-scale PN junction depths in silicon chips, enabling faster, non-contact ...

Water makes up around 60% of the human body. More than half of this water sloshes around inside the cells that make up organs ...

Background: Epithelial barrier function is impaired in Crohn’s disease. Aim: To define the underlying cellular mechanisms with special attention to tight junctions. Methods: Biopsy specimens from the ...

Two major reasons why chemotherapy and immunotherapy have limited efficacy in treating gliomas are the blood-brain barrier and the dense, solid structure of the glioma. Pulsed electric fields have ...

The key structure of the physical barrier consists of intestinal epithelial cells, which are tightly connected by specialised structures such as tight junctions, desmosomes, and adherens junctions.

Tight junctions must be able to adapt to cell shape change and still be able to seal the gaps," explains Prof. Honigmann, chair of Biophysics and research group leader at the BIOTEC.

"This suggests that tight junctions block cells from responding to signals in gastrulation models, and more fundamentally, that the structure of cells is very important to how they receive ...

“Tight junctions between adjacent cells seem to make them impervious to signals from BMP4,” Vasic says. “But the edge cells don’t have a buddy to form tight junctions with on their outer side, ...
