Phosphatidylinositol-3-OH kinase and nutrient-sensing mTOR pathways control T lymphocyte trafficking
Open accessAbstract
Phosphatidylinositol-3-OH kinase (PI(3)K) and the nutrient sensor mTOR are evolutionarily conserved regulators of cell metabolism. Here we show that PI(3)K and mTOR determined the repertoire of adhesion and chemokine receptors expressed by T lymphocytes. The key lymph node–homing receptors CD62L (L-selectin) and CCR7 were highly expressed on naive T lymphocytes but were downregulated after immune activation. CD62L downregulation occurred through ectodomain proteolysis and suppression of gene transcription. The p110δ subunit of PI(3)K controlled CD62L proteolysis through mitogen-activated protein kinases, whereas control of CD62L transcription by p110δ was mediated by mTOR through regulation of the transcription factor KLF2. PI(3)K-mTOR nutrient-sensing pathways also determined expression of the chemokine receptor CCR7 and regulated lymphocyte trafficking in vivo. Hence, lymphocytes use PI(3)K and mTOR to match metabolism and trafficking.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
