Fig 9. Model of PI3K/Akt/mTORC1 regulation of flagellin-induced TNF-α and IL-6 expression.

Fig 9

Based on our studies and other reports, we propose a model in which flagellin binds toTLR5 and transmits its signal to PI3K via MyD88. Activated PI3K stimulatesAkt/mTOR, and mTOR signaling activates NF-κB and STAT3. These factors translocate to the nucleus and enhance TNF-α and IL-6 expression, promoting cell proliferation and survival.
