With the progression of the infection a more equilibrated immunological balance is observed, with 6 genes showing significant transcription up-regulation: IFN-γ, IL-5, TNF-α, TGF-βR1, IL-21 and IL-23 and 4 extra genes showing significant down-regulation: DEFB1, CD163, IL-13 and IL-18. This evidence concerns the gene IL13 and infection.
