Abstract

mTOR is an evolutionarily conserved serine/threonine kinase that plays a central role in integrating environmental cues in the form of growth factors, amino acids, and energy. In the study of the immune system, mTOR is emerging as a critical regulator of immune function because of its role in sensing and integrating cues from the immune microenvironment. With the greater appreciation of cellular metabolism as an important regulator of immune cell function, mTOR is proving to be a vital link between immune function and metabolism. In this review, we discuss the ability of mTOR to direct the adaptive immune response. Specifically, we focus on the role of mTOR in promoting differentiation, activation, and function in T cells, B cells, and antigen-presenting cells.

  • The activation of inflammatory and growth factor regulators in the subiculum indicates convergence of mTOR/INS dysregulation with neuroimmune and receptor tyrosine kinase signaling in DS-AD.

    “Upstream regulator analysis based on the proteome identified strong activation of inflammatory and growth factor regulators, including TGFB1, TNF, EGFR, and ERBB2, particularly in the subiculum, indicating convergence of mTOR/INS dysregulation with neuroimmune and receptor tyrosine kinase signaling in DS‐AD, 65 which warrants further investigation.”

    From Disruption of hippocampal upstream regulators of mTOR and insulin pathways in Down syndrome with Alzheimer's disease neuropathology: Preliminary observations (2026) · cites this paper as [65]

    The ‘Upstream Regulation of mTOR Activity’ section says that cytokine and growth-factor receptors can activate mTOR, supporting a general connection between immune and growth-factor signaling. It does not report a subiculum proteomic analysis, activation of TGFB1, TNF, EGFR, or ERBB2, or convergence of these pathways in DS-AD. No page number is available in our copy. (LLM, conf=0.86)

    The review’s “Upstream Regulation of mTOR Activity” section discusses growth-factor and immune signaling that regulates mTOR, but does not report a proteome-based upstream regulator analysis. Searches for the named regulators, subiculum, and DS-AD found no passage addressing their claimed activation. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • IGF-1, released by microglia and able to lessen some behavioral and neuropathological features of Rett and 22q13 deletion syndrome, turns on mTOR.

    “IGF-1, which ameliorates some behavioural and neuropathologies of Rett and 22q13 deletion syndrome, and is secreted by microglia, activates mTOR230.”
  • The lack of mitochondrial biogenesis in senescent T cells may be a consequence of the failure of these cells to activate mTOR, as demonstrated by their inability to phosphorylate mTORC1 or mTORC2.

    “The lack of mitochondrial biogenesis may well be a consequence of the failure of senescent T cells to activate mTOR (mammaliam target of rapamycin), a central integrator of immune signalling and cell metabolism [62], as demonstrated by their inability to phosphorylate the mTOCR1 [25] or the mTORC2 complex [63].”

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.
