WebIn a mouse model of hepatocellular carcinoma (HCC), TOX was upregulated in exhausted CD8 + T cells, impairing their anti-tumor function. The underlying mechanism involves a TOX-induced decrease in PD-1 degradation and promotion of PD-1 … WebTOX and TOX2 are highly induced in PD-1 high TIM3 high exhausted TILs . The proteins TOX and TOX2 induce epigenetic changes and activate the transcription of genes that encode transcription factors (including Tcf7, Nr4a2 and Tox itself) and co-inhibitory receptors (including Pdcd1, Lag3, Cd244 and Havcr2) that are hallmarks of CD8 + T cell ...

TOX is induced by calcineurin and NFAT2, and operates in a feed-forward loop in which it becomes calcineurin-independent and sustained in T ex cells.
WebFeb 24, 2024 · T cell exhaustion is induced after repeated and prolonged antigenic stimulation during chronic infection. Contrary to acute infection, chronic infection provides a unique environment within which effector T cells differentiate into exhausted T cells rather than memory T cells. WebMay 19, 2024 · CD8 + T cell exhaustion is a major barrier to current anti-cancer immunotherapies. Despite this, the developmental biology of exhausted CD8 + T cells (Tex) remains poorly defined, restraining improvement of strategies aimed at “re-invigorating” Tex cells. Here, we defined a four-cell-stage developmental framework for Tex cells.
