Functional enrichment showed that at the early stage of infection (6 h), there is an over-representation of genes coding for proteins involved in phagocytosis, such as integrins and cell receptors (CD18, MR, TLR2, and TLR4), proteins related to lysosomes (LAMP, LIMP, DMXL, WDR7, and NCOA7), and components of the NF-kB signaling pathway (LYN, VAV, BCAP, NFKB, NFAT, API, and CARMA1) (Figure 6A,B) (Table S2). This evidence concerns the gene VAV1 and infection.
