To elucidate how infection-induced changes in metabolic and immunological pathways influence host susceptibility and pathology in mice infected with Echinostoma caproni.
Key Findings:
Strong upregulation of proteins involved in mitochondrial oxidative phosphorylation, purine metabolism, and the renin–angiotensin system.
Downregulation of proteins linked to fatty acid β-oxidation, nucleotide binding, vesicular trafficking, and tight junction maintenance.
Overexpression of antimicrobial peptides and reduced eosinophil- and neutrophil-derived effectors, indicating a skewed Th1-biased immune response.
Interpretation:
The primary E. caproni infection induces significant metabolic and immunological reprogramming, leading to mitochondrial dysfunction, oxidative stress, and epithelial barrier disruption, which collectively contribute to a pro-inflammatory environment that favors chronic infection.
Limitations:
Study focused solely on male ICR mice, limiting generalizability to other genders or species.
Proteomic analysis may not capture all relevant biological changes associated with infection, potentially overlooking critical factors.
Conclusion:
The findings provide insights into the molecular basis of host susceptibility to intestinal helminths, potentially guiding future therapeutic or preventive strategies.
