Previously we have shown that transcription factor Foxp1 plays an essential role
in maintaining naive T cell quiescence; in the absence of Foxp1, mature naive
CD8(+) T cells proliferate in direct response to homeostatic cytokine IL-7. In
this study, we report that the deletion of Foxp1 in naive CD8(+) T cells leads to
enhanced activation of the PI3K/Akt/mammalian target of rapamycin signaling
pathway and its downstream cell growth and metabolism targets in response to
IL-7. We found that Foxp1 directly regulates PI3K interacting protein 1, a
negative regulator of PI3K. Additionally, we found that deletion of Foxp1 in
naive CD8(+) T cells results in increased expression levels of E2fs, the critical
components for cell cycle progression and proliferation, in a manner that is not
associated with increased phosphorylation of retinoblastoma protein. Taken
together, our studies suggest that Foxp1 enforces naive CD8(+) T cell quiescence
by simultaneously repressing key pathways in both cellular metabolism and cell
cycle progression.
