TLR4 and infection: Additionally, we observed a modest, yet non-significant increased activation of the Toll pathway as measured by expression of Drosomycin at 18 hours post infection (p = 0.15, Fig. 5b) and a slight decrease in Jak-Stat activation as measured by transcriptional expression of Eiger at 18 hours post infection (p = 0.09, Fig. 5c).
