Hypothesis
This study investigates the pathogenic mechanisms of Aeromonas veronii in macrophages.
Conclusion
Aeromonas veronii induces higher levels of inflammation and apoptosis in human macrophages compared to E. coli.
Supporting Evidence
- Aeromonas veronii significantly upregulated pro-inflammatory cytokines IL-8, IL-1β, IL-18, and TNFα.
- Aeromonas veronii induced higher levels of apoptosis in THP-1 macrophages compared to E. coli.
- Aeromonas veronii downregulated histone encoding genes, which may impair macrophage function.
Takeaway
Aeromonas veronii makes our immune cells very active and can even make them die, which might help it cause sickness.
Methodology
THP-1 derived macrophages were treated with A. veronii or E. coli, followed by RNA sequencing and protein level measurements of cytokines.
