Bacterial biofilms represent a challenge to the healthcare system because of their resilience against antimicrobials and immune attack. Biofilms consist of bacterial aggregates embedded in an extracellular polymeric substance (EPS) composed of polysaccharides, nucleic acids and proteins. We hypothesised that carbohydrates could contribute to immune recognition of Pseudomonas aeruginosa biofilms by engaging C-type lectins.

Multiple virulence factors produced by are controlled by quorum sensing (QS) 2-alkyl-4(1)-quinolone (AQ) signal molecules. Here, we investigated the impact of AQs on PAO1 infection of differentiated human bronchial epithelial cells (HBECs).

Differently activated macrophage populations with distinct inflammatory and microbicidal potentials have been described. Our previous work unveiled a positive and a negative correlation between levels of gamma interferon (IFN-γ) and interleukin-17A (IL-17A), respectively, and lung function in cystic fibrosis, particularly in patients chronically infected with This study sought to define key parameters in human antibacterial immunity under Th1- and Th17-dominated inflammatory conditions; the final aim was to identify unique characteristics that could be fine-tuned therapeutically to minimize tissue damage while maximizing bacterial clearance.

In Africa, children are highly valued for social, cultural and economic reasons. Infertile and childless women in Africa are therefore confronted with a series of societal discrimination and stigmatization which may lead to psychological disorders such as anxiety and depression.
