Cells of organs and tissues commonly communicate directly with one another via permeable membrane junctions. Cell-to-cell channels, spanning the width of both membranes of a junction, are thought to ...

Tight junctions are one mode of cell–cell adhesion in epithelial and endothelial cellular sheets. They act as a primary barrier to the diffusion of solutes through the intercellular space, create a ...

This is a preview. Log in through your library . Abstract Recently, we found that ZO-1, a tight junction-associated protein, was concentrated in the so called isolated adherens junction fraction from ...

Underneath their smooth surface mitochondria harbor an elaborately folded inner membrane. It holds a multitude of bottleneck like invaginations, which expand into elongated cavities. Now researchers ...

Oliver Daumke's lab figures out how the inner membranes of mitochondria "get their groove" and assume the complex shapes they need to carry out crucial cellular functions. About two billion years ago, ...

The ebb and flow of intracellular calcium concentrations is a universal mode of communication in mammalian cells. Researchers have now identified the matchmaker that brings two critical calcium ...

The mucosal route plays an important role in nanoscale delivery. The nanoscale systems have to penetrate or diffuse through the mucosal membrane to reach the epithelium as depicted in Figure 3A & B.

In their May 2015 Scientific American article “Cellular Small Talk,”Dale W. Laird, Paul D. Lampe and Ross G. Johnson report on recent discoveries showing that the disruption of cellular structures ...
