- Dexamethasone decreases glycolysis and inflammatory cytokine production in human lung and blood macrophages.
- Treated macrophages show increased survival and reduced bacterial load via enhanced autophagy and phagosomal acidification.
- Macrophage responses to glucocorticoids differ based on tissue origin, influencing treatment strategies.
- Findings support steroid use alongside antimicrobials to balance inflammation control with effective infection defense in tuberculosis.
Our study shows that dexamethasone, which is known to dampen inflammation, can also help macrophages fight tuberculosis more effectively. This challenges the assumption that steroids always suppress immunity and opens the door to smarter, targeted adjunctive therapies that balance inflammation control with antimicrobial defense.— Dr. Donal Cox, senior research fellow, Clinical Medicine, Trinity College Dublin
