Analysis of the vessel data revealed several proteins related to the acute-phase response to infection (Hp, Hpx, Serpina3n, Fga/b, Igfbp7, Cfh, and C4b), antigen presentation (Tap1, Tap2, Tapbp, H2-D1, and H2-Q10), and interferon response (Igtp, Gbp2, Irgm1, and Iigp1) (Fig. 2E). Here, HPX is linked to infection.
