Photography from the intestinal cavity to their surface using a scanning electron microscope. You can see groups of bubbles protruding from the surface of the goblet cells, on their way to be released into the intestinal cavity. In a mouse without inflammasome, the bubbles are prominent but not secreted

The experimental system: two nostrils from which exit ultrasonic beams of excited helium atoms (in blue) and of argon atoms or hydrogen molecules (in red). The blue beam passes through a magnetic device (in yellow) which causes it to bend, and merges with the red beam - then the argon atoms or hydrogen molecules undergo ionization, and enter the detector. The picture above shows a cross-section of the magnetic device
