NFKB1 and infection: Moreover, specific transcriptomic changes in cerebral cortex post infection (Figs. 3C, 3D, S3A, and S3B) showed that the down-regulated genes were mainly related to synapse, locomotory behavior and learning terms (Fig. S3C), while up-regulated ones participated in muscle contraction, transcription, angiogenesis and nuclear factor-kappa B (NF-κB) signaling pathways (Fig. 3E).
