Three members of the tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein were affected by the Tulahuen strain infection: downregulated the eta (Ywhah, −1.8-fold) and zeta (Ywhaz, −1.8-fold), and upregulated the theta (Ywhaq, 1.8-fold) (Figure 3C). The gene discussed is GABRQ; the disease is infection.
