In plain English

AI plain-English summary

The bacterium *Staphylococcus aureus* is building a sugar-coated armour on its cell wall, and this network of 14 PhD students aims to strip it bare. This matters because *S. aureus* is a leading cause of hospital-acquired infections, and many strains now shrug off multiple antibiotics. The researchers are focusing on wall teichoic acids (WTAs)—complex sugar polymers that stud the bacterial surface. These molecules are both essential for the bacterium’s survival and highly conserved across strains, making them promising targets. Yet their exact structure and how the human immune system recognises them remain poorly understood. If the project succeeds, it could lead to entirely new classes of immune-based therapies—vaccines or antibodies that latch onto WTAs instead of the usual, mutation-prone protein targets. This would give doctors a fresh weapon against drug-resistant infections, reducing the need for last-resort antibiotics in hospitals and nursing homes. The project is fundamentally curiosity-driven, rooted in chemical biology. It will first map the biosynthesis and precise shape of WTAs, then probe how human immune cells respond to them. Past fundamental work on bacterial surface molecules has already yielded blockbuster vaccines (e.g., against *Haemophilus influenzae*), so a deeper understanding here could similarly open unexpected therapeutic doors.

View original technical description
The AUREUS doctoral network meets the increasing need of a highly qualified work force to counteract multidrug-resistant S. aureus infections by performing cutting-edge, inter-disciplinary research in the multifaceted field of chemical biology. The proposed research program aims at training Doctoral Candidates (DCs) to acquire complementary skills to exploit and develop different and innovative strategies to i) unveil the biosynthesis and structure of unique S. aureus cell wall glycopolymers, the so-called WTA (wall teichoic acids), ii) gain greater insights into the molecular basis of the human immune responses to S. aureus WTA, iii) harness the acquired knowledge to rationally design and develop effective immune-based therapies against S. aureus and related bacterial species. To this end, the AUREUS intersectoral program is based on a unique international team combining expertise in different fields including chemistry, (micro-)biology and immunology. In detail, 9 world academic leaders in the glycoscience and/or S. aureus research world and 4 companies (SMEs) with world-class expertise in glycoscience, cutting-edge diagnostics and therapeutic research programs will be involved in the AUREUS project. Each DC will have their own individual project, based on fundamental science and with practical applications, either in biotechnology or in biomedicine, as will be explored through secondments with our industrial partners. The AUREUS network will provide 14 young scientists with broad, top-class scientific and professional competences and skills, thereby expanding the pipeline of future leaders for both industry and academia.
