In addition, the highly induced CPs (P < .0001) at 2 h post-infection were Neuroinflammation Signaling, TLRs, PPRs, IL-6, and NF-kB Signaling (Figure 2(c)); while at 24 h, the highly induced CPs (P < .0001) were TLRs, Neuroinflammation Signaling, PPRs, IL6, and TREM1 Signaling (Figure 2(d)). Here, TREM1 is linked to infection.
