IKBKB and Salmonella Infections: Similarly, Salmonella infection (MOI = 1) caused lower levels of p-p65 protein in Slc30a1 cKO BMDMs at 60 min compared to infected Slc30a1fl/fl cells (Figure 5H—source data 1), as well as reduced mRNA levels of several genes upstream of the NF-κB pathway, including p65, MyD88, Ikkα, and Ikkβ (Figure 5I).
