ITIH2 and infection: Additionally, many genes associated with metal homeostasis (e.g., ceruloplasmin, serotransferrin-2, hemopexin), and the acute phase response (e.g., fetuin-A, inter-alpha-trypsin inhibitor heavy chain H2, serum albumin 1, apolipoprotein B-100) were significantly upregulated in this group prior to infection with Asal.
