An innovative therapeutic approach mobilizes viruses to intercept disease-causing gut bacteria

In a study published today in the scientific journal Cell, Weizmann Institute of Science scientists demonstrated an innovative therapeutic approach that performs "targeted defeat" of unwanted intestinal bacteria using a creative and precise weapon - viruses that attack bacteria

The smoking gun of the link between smoking cessation and obesity: gut bacteria

Nicotine and other compounds found in cigarettes penetrate the intestine through the bloodstream and change the composition of the intestinal bacteria and their products

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
