Repurposing disused antibiotics with immune modulators as antimicrobial strategy for respiratory tract infections
Respiratory tract infections are common and are increasingly caused by bacteria that are no longer sensitive to commonly used antibiotics.
Objective
This project aimed to expand the therapeutic arsenal against respiratory tract infections by testing agents that stimulate the immune system.
Results
The AMC had 2 specific tasks. First, a culture system of human respiratory epithelial cells was set up; in this culture system, 2 immune modulators (metformin and rapamycin) were found to have an inhibitory effect on the production of inflammatory proteins. Secondly, 3 immunomodulators were tested in a mouse model of pneumonia, 2 of which (rapamycin and pioglitazone) were found to have a beneficial effect on the immune response. Although further research is needed before any clinical application can be considered, these results suggest that modulating the immune response may be helpful in treating patients with pneumonia.
