WebFeb 2, 2024 · T cell exhaustion is defined as progressive loss of effector function (loss of IL-2, TNF-α, and IFN-γ production) and sustained expression of inhibitory receptors such as PD-1, T cell immunoglobulin domain, and mucin domain-containing protein 3 (Tim-3), CTLA-4, lymphocyte-activation gene 3 (LAG-3), and CD160 with a transcriptional program … WebMar 25, 2024 · TOX is a member of a family of transcriptional factors that contain the highly conserved high mobility group box (HMG-box) region. Its expression is upregulated in dysfunctional T cells, driven by chronic T cell receptor stimulation and activation of transcription factors known as nuclear factor of activated T cells (NFATs).
