Scientists at Karolinska Institutet in Sweden have presented a new principle for fighting bacterial infections, in other words, a new type of antibiotic, in the FASEB Journal. The new antibiotic mechanism is based on selectively blocking the thioredoxin system in the cells, which is crucial to the growth of certain bacteria. Scientists hope to be able to treat such conditions as stomach ulcers, TB and MRSA.
“Much work remains to be done, but we believe that it will be possible to use this mechanism when, for example, broad-spectrum antibiotics have proved to be inadequate”, says Professor Arne Holmgren, leader of the study now being published.
