American biochemist received this year's Inhoffen Medal
How do bacteria cope when exposed to toxic mercury, how are they able to outlast antibiotics, and how can they be killed using so-called "suicide inhibitors"? These are but a few of the many research topics US biochemist Christopher Walsh has devoted his career as a…
Blockade of pathogen's metabolism
In the search for new antibiotics, researchers are taking an unusual approach: They are developing peptides, short chains of protein building blocks that effectively inhibit a key enzyme of bacterial metabolism. Now, scientists at the Helmholtz Institute for…
New hope in fight against multi-resistant germs
An increasing number of bacteria is evolving antibiotic resistance. Much-feared representatives of this steadily growing group include Staphylococci strains. At this point, multi-resistant forms of the bacterium Staphylococcus aureus - the "hospital germ" known commonly…
Helmholtz International Fellow Award for Lorne Babiuk
On Wednesday, the vaccine researcher Prof. Lorne A. Babiuk was appointed "Helmholtz International Fellow" by the Helmholtz Association of German Research Centres in Berlin. He had been nominated by the Helmholtz Centre for Infection Research (HZI) in Braunschweig. The…
Immune system molecule with hidden talents
Dendritic cells, or DCs for short, perform a vital role for the immune system: They engulf pathogens, break them down into their component parts, and then display the pieces on their surface. This in turn signals other immune cells capable of recognizing these pieces to…
Sensor of bacteria and viruses on high alert at the site of action
"Danger!" signals TLR9, the molecular sensor, whenever it recognizes bacterial or viral genetic information, specifically DNA. Instantly, the immune system initiates the process of fighting off the infection. This initial protective mechanism is very fast because it…
Bacterial toxin sets the course for infection
Every year gastro-intestinal diseases have lethal consequences for more than five million individuals. Researchers from Braunschweig have now discovered what makes a specific strain of Yersinia pseudotuberculosis –one of the main instigators for these infections–so…
Valerie Mizrahi appointed Helmholtz International Fellow
Along with Aids and malaria, tuberculosis is one of the “big three” infections” of today. This means that it is one of the infectious diseases killing most people worldwide. Every 20 seconds a person dies from tuberculosis, which is caused by the pathogen Mycobacterium…
Focus on the innate immune response
The innate immune response to bacterial, viral and parasitic infections is the main topic of this year's “North-Regio-Day on Infection” meeting, short NoRDI IV. The symposium, entitled “Innate Immunity of Infections”, takes place on 24 October at the Helmholtz Centre…
Joint forces against Hepatitis viruses
To address pressing questions about infectious diseases jointly is the main goal of a new collaborative effort between the University of Alberta (UofA), Canada, and the Helmholtz Association. On 23 September, their research partnership was sealed at the Braunschweig…
