Hallmarks of T-cell Exit from Quiescence The appropriate activation of the adaptive immune system relies upon the reprogramming of naïve T cells into specialized effector T cells that can combat pathogens and tumors. Naïve T cells are actively maintained in a state of hyporesponsiveness termed quiescence, which is characterized by small ce.
5/1/2018 · The hallmarks of T-cell exit from quiescence . A, Naïve T cells are actively maintained in a quiescent state defined by residing in stage G 0 of the cell cycle. During the ?25–30 hours window following TCR and costimulatory receptor activation, T cells undergo quiescence exit, which is defined by six key hallmarks shown in white text within the large cell in the center.

During the 25–30 hours window following TCR and costimulatory receptor activation, T cells undergo quiescence exit, which is de?ned by six key, Engagement of antigen and costimulatory receptors drives T cells to exit quiescence to promote subsequent clonal expansion and functional differentiation. The exit from quiescence, which precedes…

12/12/2013 · Naive T cells respond to antigen stimulation by exiting from quiescence and initiating clonal expansion and functional differentiation, but the control mechanism is elusive. Here we describe that Raptor-mTORC1-dependent metabolic reprogramming is a.
The identification of genes involved in cell cycle exit and quiescence provides new hints for further studies on the molecular mechanisms regulating the non-dividing state of a cell, the mechanisms closely related to cancer development and to many biological processes. … Hierarchical clustering analysis of selected memory T cell genes.
6/11/2019 · However, quiescence can become deregulated in pathological settings. In this review, we discuss the recent advances uncovering intracellular signaling pathways, transcriptional changes, and extracellular cues within the stem cell niche that control induction and exit from quiescence .
11/9/2020 · In T lymphocytes, quiescence and the timely exit from arrest upon binding of a cognate antigen to the T cell receptor are essential for mounting an appropriate immune response (Hwang et al.
2020). Quiescence is also important in oocytes for the maintenance of reproductive capacity.
Tight control over SC quiescence entry and exit is actively maintained through intrinsic mechanisms, systemic factors, and interactions with the microenvironment. Cells in this state are characterized by lower metabolic activity, generating ATP via the glycolytic pathway rather than oxidative phosphorylation (Arai and Suda, 2008
