ACOD1 and infection: Considering the previous study have shown that an infection response gene-1 (irg-1) was robustly induced upon P. aeruginosa infection which process is controlled by ZIP-2 and CEBP-2 (27, 32), the reporter strain irg-1p::GFP was introduced to further investigate the relationship between ZIP-11 and CEBP-2 in vivo.
