secreted

These are tiny bubbles of lipids that are secreted by cells of the body and that can ultimately enter the bloodstream.

When this mutual recognition was established, the plant will modify the panel of root secreted molecules and by this will affect which soil bacteria can grow in the vicinity of their roots.

The approach involves genetically modifying a particular organ within an animal so that its cells affix a marker, the molecule biotin, to proteins due to be secreted.

Bacteria adapt to their environments by utilizing specialized proteins, which can be secreted into the surrounding medium or bound to their cell membranes.

The researchers traced the effect to an enzyme secreted by the bacterium that makes the gut acidic, apparently deforming proteins that viruses need to invade insect cells.
