Discovery of a New Action of Macrolide Drugs: Suppresses Proinflammatory Components Released by Streptococcus pneumoniae
May 23, 2023
A research group led by Associate Professor DOMON Hisanori and Professor TERAO Yutaka of the Division of Microbiology and Infectious Diseases, Graduate School of Medical and Dental Sciences, Niigata University discovered that azithromycin and erythromycin, macrolides drugs1, prevent exacerbation of inflammation by suppressing the production of inflammation inducers released by Streptococcus pneumoniae. The research was published in the online version of the US scientific journal Microbiology Spectrum on May 16, 2023.
Research results
- Streptococcus pneumoniae releases proinflammatory components such as peptidoglycan and lipoproteins, causing inflammation in the body.
- This research discovered that macrolides suppress the production of these proinflammatory components .
- The research may lead to the development of a treatment for pneumonia that targets bacterial proinflammatory components.
[Glossary]
1. An antibacterial agent that suppresses protein synthesis in bacteria.
