Figure 1From: The gastrointestinal nematode Trichostrongylus colubriformis down-regulates immune gene expression in migratory cells in afferent lymphAnalysis of transcript levels of Th2 effector cytokines. The level of IL-4 (open triangle), IL-5 (black square), IL-13 (black triangle) and IFNγ (black circle) transcripts in sample pools were measured by qRT-PCR. Expression levels were normalised to PI level. PI = week 0, I1 = week 1, I2 = week 4, I3 = week 7, C1 = week 10, C2 = week 11, C3 = week 12.Back to article page
