Our skin and mucous membranes are protected by epithelial cells. This barrier tissue performs its function thanks to ...

Tight junctions (blue dots) between cells are connected areas of the plasma membrane that stitch cells together. Adherens junctions (red dots) join the actin filaments of neighboring cells together.

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 membranes are protected by epithelial cells.

Our skin and mucous membranes protect us like vigilant sentinels against the onslaught of harmful pathogens. This extraordinary defense owes its strength to epithelial cells—specialized tissues woven ...

Protein complexes within each cell further connect the transmembrane adhesive proteins to the cytoskeleton. In particular, adaptor complexes bind adherens junctions to cytoskeletal actin ...

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments ...

What am I looking at? This is a video of two so-called HeLa cells that are labeled with a marker for an actin cross-linking protein. The thin tendrils extending from the cell and waving around are ...
