Research summary

Our laboratory investigates the molecular mechanisms underlying the development of bacterial infections. We work at subcellular level studying the structural and biological role of the so-called bacterial lipid rafts and the role that these subcellular platforms play in the regulation of signaling in pathogens like Staphylococcus aureus. We also work at multicellular level, exploring how microbial communities evolve during an infection process. Our goal is to develop new strategies and antimicrobial therapies to eliminate infection diseases.

A number of bacterial cell processes are confined in platforms termed functional membrane microdomains, some of whose organizational and functional features resemble those of lipid rafts of eukaryotic cells. How bacteria organize these intricate platforms and their biological significance remains an important question. My laboratory is a key laboratory in the field of functional membrane microdomain bacterial compartmentalization and its role during infections, using MRSA (Methicillin-resistance Staphylococcus aureus) as model organisms. Our research is supported by competitive funding, such as ERC-StG-2013 or H2020 RIA Biotech-03-2016. We aim to identify the structure and molecular mechanisms that leads to bacterial membrane compartmentalization and their role during staphylococcal infections that are resistance to antibiotic treatments. To do this, we work in the interface of molecular and cellular biology with other scientific disciplines, such as structural, infection, synthetic and systems biology. This interactive and multidisciplinary environment provides to my laboratory a means to open new areas to study new mechanisms of bacterial infections and to discover new antimicrobial strategies to fight antibiotic resistance and multi-drug resistance pathogens, with special emphasis on those associated with hospital infections.
