ALB and infection: Only at 6 h post-infection, the expression level of albumin increased significantly in WT mice (unpaired t-test; WT 0 vs. 6 h: p < 0.05), while expression level of albumin increased significantly 24 h post-infection in KO mice (unpaired t-test; KO 0 vs. 24 h: p < 0.05); at 48 h post-infection, both mice returned to basal level before infection.
