Tuberculosis: Researchers uncover how bacteria burst our cells

Scientists unveil the complex molecular structure that causes lethal infections by Mycobacterium tuberculosis (Mtb). Their findings might have implications for potential therapies against antibiotic-resistant tuberculosis.
In a paper published this week in Nature Microbiology, an international team of scientists describe the overall architecture of an assembly of proteins known as Type VII (T7SS) secretion systems found in a group of bacteria which cause diseases such as tuberculosis.
T7SS-systems play a key role in tuberculosis infections and might present important targets for much needed new drugs: blocking these systems could prevent the bacteria from bursting the host cells and could thus alleviate the infection.
Now further biochemical and genetic experiments will be carried out to support the structural data and to provide in vivo insights into the components required for assembly of the T7 secretion system.
