On the other hand, FOXO signaling (TNFSF10, PRKAB1, GADD45B, STK4, STAT3), Salmonella infection (ARPC2, ARPC5L, CCL3L3, CCL4) and lysosome (LAPTM4B, HGSNAT, CD164, ATP6V0A2) pathways were up-regulated, albeit weakly, in the HLA-DR- Teff subset (Fig 6B). Here, STK4 is linked to Salmonella Infections.
