The macromolecule of peptidoglycan (or its small components) can induce an inflammatory response in different hosts. We believe that in order to understand how this macromolecule is sensed by the infected host we will need to learn how this molecule is synthesised, organised, modified and degraded during the bacterial cell cycle. There are four essential questions that represent the different research lines being followed in our laboratory: 1. Does the composition of the peptidoglycan interfere with its recognition by the host? 2. Does the metabolism of the peptidoglycan, as the bacteria divides into two daughter cells, interfere with its recognition by the host? 3. Are polysaccharides, linked to the bacterial surface, capable of interfering with peptidoglycan recognition? 4. Are there other bacterial strategies to hide the inflammatory peptidoglycan macromolecule? We often use Staphylococcus aureus and Streptococcus pneumoniae, Gram-positive bacterial pathogens, as model organisms to study how the metabolism of the bacteria cell surface, mainly cell wall synthesis and turnover, can modulate a response of the innate immune system of the infected host.
