The pathways including WNT/β-catenin signaling, Th1 and Th2 activation, RAR activation, NGF-stimulated transcription, IL-15 production, and IL-4, 7, 12, and 13 signaling are the top pathways that the nematode infection elicits, which could lead to eventual protection or immune evasion. This evidence concerns the gene NGF and Nematoda infectious disease.
