This research reveals how single and co-infections with distinct T. cruzi strains shape cytokine responses, suggesting implications for Chagas disease therapy.
Key Points
Co-infection with phylogenetically distinct T. cruzi strains creates a unique immune profile in macrophages.
The Y strain induces a strong pro-inflammatory response with elevated IL-1β, IL-18, and NO production.
G strain promotes regulatory signals, increasing IL-10 while decreasing inflammatory cytokines over time.
Macrophage responses are modulated by the parasite population's composition, highlighting the importance of genetic diversity.
