The significant GO terms and enriched pathways identified in single infection vs. pre-infected samples consisted of various immune-relevant terms such as “defense response”, “steroid biosynthesis”, “PPAR signaling pathway”, “Cytokine-cytokine receptor interaction”, “extracellular matrix”, “metallopeptidase activity”, “Intestinal immune network of IgA production” and “adaptive immune response” (Figure 6A). Here, PPARA is linked to infection.
