From the fluid mosaic model to tight junctions, cell membranes are the ultimate gatekeepers of life. They manage what comes in and out, maintain balance, and even signal to other cells. Understanding ...

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 ...

In pink, wild type cells expressing gamma actin. In black, knock-out cells that do not express gamma actin. The yellowish lines reveal the tortuous nature of the junctions. Our skin and mucous ...

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 ...
