Codonopsis pilosula polysaccharide attenuates the inflammatory response in macrophages induced by Brucella abortus outer membrane protein 19 via regulating ATP2A1 to modulate cell adhesion and calcium signaling
To investigate the effects of Codonopsis pilosula polysaccharides (CPPS) on the inflammatory response specifically induced by Brucella outer membrane protein 19 (OMP19).
Key Findings:
CPPS significantly alleviated tissue damage and downregulated HMGB1, E-cadherin, and paxillin, indicating reduced inflammation.
Inhibited SYK/FAK/AKT phosphorylation, PKC activation, and WNT-1 signaling pathway transduction, demonstrating a multifaceted anti-inflammatory mechanism.
Downregulated pro-inflammatory cytokines (TNF-α, IL-6) while increasing IL-10 levels, suggesting a shift towards an anti-inflammatory profile.
Reduced intracellular calcium ion (Ca2+) concentration, which may contribute to the modulation of inflammatory responses.
ATP2A1 was identified as a key gene involved in the anti-inflammatory effects of CPPS, highlighting its potential as a therapeutic target.
Interpretation:
CPPS attenuates macrophage inflammation induced by OMP19 through the regulation of ATP2A1, which affects cell adhesion and calcium signaling pathways, thereby reducing inflammatory responses.
Limitations:
The study primarily focuses on specific signaling pathways and may not encompass all mechanisms involved in brucellosis, indicating a need for broader investigations.
Further research is needed to fully elucidate the therapeutic potential of CPPS in brucellosis and explore other possible mechanisms.
Conclusion:
CPPS show potential in reducing macrophage inflammation in the context of Brucella infection, suggesting their role as a promising therapeutic agent.
