Gap junctions are specialised intercellular channels that facilitate direct communication between adjacent cells by allowing the regulated exchange of ions, second messengers and small metabolites.

Developmental biologists have discovered that during egg development in fruit flies, intercellular gaps open between epithelial cells in a controlled way at the points where three cells meet. This ...

Filamentous cyanobacteria represent a distinctive group of oxygenic photoautotrophs that exhibit a remarkable form of prokaryotic multicellularity. These organisms form elongated trichomes in which ...

Within multicellular organisms, cells build connections with each other forming cell layers that cover the surfaces of tissues and organs and separate structures in the body. For example, the skin ...

The formation of a cancer is proven to be a multi-stage, multi-mechanism process by animal and human studies. As a definite carcinogen, the role of Helicobacter pylori (H pylori) in the formation of ...

Northwestern Medicine investigators have discovered a novel mechanism linking an intercellular adhesion molecule with genetic inflammatory skin diseases, according to findings published in the Journal ...

This is a nice example of a rather unexpected discovery: by studying the development of the blood vessels of the brain, researchers have just shed light on a question that was pending for 10 years!

Scientists at Feinberg are reshaping scientific understanding of the cell's tiniest components—structures once thought to be static, now revealed to be dynamic engines of cellular life. As they probe ...

With the increasing exploration of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the causative pathogen of coronavirus disease 2019 (COVID-19) pandemic – it has become clear that ...
