In light of the growing resistance to antibiotics, treating infections is becoming increasingly difficult. Effective treatment should aim to eliminate harmful pathogens while preserving the beneficial human microbiota. Advances in molecular biology make it possible to design targeted tools that act not only on specific bacterial species, but even on individual strains.
One promising approach focuses on proteins that interact with DNA, known as transcription factors. By altering gene expression, these proteins can control key bacterial processes, including those linked to virulence. Targeting these regulatory mechanisms offers a way to disarm pathogens rather than simply kill them.
Another highly interesting aspect is the thermal stability of antibacterial agents. The use of enzymes originating from hot spring environments (~100°C), in fusion with antimicrobial peptides, enables efficient pathogen elimination while preserving the activity of the formulation even at elevated temperatures.
An equally important perspective concerns not only the treatment of infections, but also prevention, for example, protecting food products against bacterial contamination.
