These brief peptide sequences in the antigen are often presented over the cell surface area of APCs by using MHCII substances, which are necessary for activation of Compact disc4+ T cells (102). (exposed-skin-care.net)
At its simplest, the problem was inserting a transistor constructed on a flat plane (think of the surface of a computer chip) into a three-dimensional object: a cell perhaps 10 microns in size. (harvardmagazine.com)

Researchers working with flies describe that the concentration of some small intracellular organelles determines the branching capacity of tracheal cells. (sciencedaily.com)
In the article, they demonstrate that cells that hold more than two centrosomes form more branches (a single cell is like a small tree with many branches). (sciencedaily.com)
The sea creatures coordinate their behaviour thanks to peptidergic cells, special types of cells that release small peptides which can direct the animal's movement or feeding. (sciforums.com)
Hyman professor of chemistry Charles Lieber and his colleagues used nanowires to create a transistor so small that it can be used to enter and probe cells without disrupting the intracellular machinery. (harvardmagazine.com)

Vale, R. D. The molecular motor toolbox for intracellular transport. (nature.com)
What makes them so interesting for our studies on intracellular transport is that they are very dynamic organelles. (ruhr-uni-bochum.de)
Intracellular transport. (setur.fo)
The result came a bit as a surprise, as we fully expected a problem with transport of these organelles would be present in all the disease models and missing in all the controls. (mytum.de)
others measured surrogates for organelle transport deficits instead of observing transport directly. (mytum.de)
This suggests that, at least for ALS, axonal organelle transport may be an unsuitable therapeutic target. (mytum.de)
