Cells in humans and all vertebrates are tightly packed together to form organs and glands — tissues essential for living, breathing and moving. “In humans, three families of membrane proteins in ...
Structure of SARS-CoV-2 envelope protein-epithelial cell junction protein complex explains virulence
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 ...
Our bodies and organs are shielded from the external environment by tissue barriers like the skin. These barriers must be tightly sealed to prevent unwanted substances from entering. This sealing is ...
Whether there are endogenous adult heart progenitors that can replenish damaged muscle cells remained controversial. Now researchers at Karolinska Institute in Sweden show that the outermost layer of ...
Cell-to-cell junctions were visualized by ZO1-GFP, and the dynamics of cell junctions were captured by movies. When the cells indicated by * were spontaneously stretched, a continuous belt of cell ...
As a human embryo grows, a set of molecules directs cells as they multiply and take on specific identities and spatial positions within the embryo. In one crucial step known as gastrulation, these ...
Cells in humans and all vertebrates are tightly packed together to form organs and glands — tissues essential for living, breathing and moving. The narrow spaces between cells represent natural weak ...
